    Abstract In order to find a reasonable way to return the straw and reduce waste of resources, sustainability assessment of four types of maize straw circulation modes, straw direct returning to the farmland (control), “straw-biogas-straw” (S-B-S), “straw-dairy-straw” (S-D-S) and “straw-dairy-biogas-straw” (S-D-B- S ), are analyzed and compared. Based on the Emergetic Ecological Footprint (EEF) method, which is an integration of Ecological Footprint (EF) analysis and emergy accounting, the Footprint Investment per unit of Footprint Delivered (FIFD) was used as an indicator of the sustainability of an ecological system. The results showed that the FIFDs for these straw circulation modes were 0.81, 1.96 and 0.43, respectively, and a sustainability sequence of S-D-B-S>S-B-S>S-D-S, in which S-D-B-S has the highest sustainability and S-D-S is unsustainable. Therefore, the agriculture-biogas mode is better than the agriculture-livestock mode, and longer circulation chains correspond with stronger sustainability. Based on the results, we suggest that integrated-biogas subsystem should be developed and all wastes in agrosystem should be used more efficiently in order to increase the sustainability. Highlights Resource-circular agriculture is better for agricultural sustainable development. Agriculture residues should be multi-level and fully utilized. The “straw-dairy-biogas-straw” circulation mode has the highest sustainability. More policies should be established to lengthen the circulation chain.

    초록

    Abstract Hou et al. (2016) recently developed a water quality index (WQI) for assessing water quality of five typical reservoirs. Despite all the merits of the practical WQI, it suffers from lack of uncertainty consideration; a fact that motivated the present discussion focusing on mitigation of uncertainty in water quality assessment. In this regard, superiority of employing fuzzy WQI (FWQI) rather than crisp WQI is emphasized. Due to robustness of FWQI in handling uncertainties surrounding data acquisition, employment of fuzzy concept can improve water quality assessment and monitoring to generate results which are more consistent with real world conditions.

    Abstract Ecosystem water use efficiency is an important indicator of carbon and water cycle coupling. This study presents a new measure of water use efficiency, soil water use efficiency (SWUE), based on gross primary production and surface soil moisture derived from remote sensing products (ECV-SM). Variation in SWUE among biomes, climate conditions, and latitudes from 2000 to 2014 was comprehensively assessed. Average global SWUE over this 15-year period was approximately 3.47 gC/kgH 2 O. SWUE was relatively high for ecosystems near the equator and decreased gradually with increasing latitude. At the biome level, high SWUE was measured in evergreen broadleaf forests, and lower values were found in shrublands. Compared with two other commonly used indicators of water use efficiency, EWUE (ratio of gross primary production to evapotranspiration) and RUE (ratio of gross primary production to precipitation), average SWUE from 2000 to 2014 was significantly higher and had the largest range of values. In addition, spatial distributions of these three indicators varied greatly. The new indicator SWUE will help promote understanding of soil water use in various ecosystems.

    Abstract The environmental risk of trace metals (TMs) in a former lead (Pb)-silver (Ag) mining district in the Vosges Mountains (France) was assessed based on two biological indices: (i) the excess of transfer TM from the soil to biota (SET index) and (ii) the toxicological risk associated with these excess transfers (ERITME index). This study constitutes the first application of the SET and ERITME indices on a past contaminated site with the inclusion of Ag and of two exposure durations. Among the eight stations studied for TM transfers in a soil-plant-snail ( Cantareus aspersus ) system, an excess of transfer (Ag, arsenic (As) and Pb mainly) was highlighted in four of the stations. High concentrations of Pb, up to 2810±978μgg −1 , were measured in snails exposed to the contaminated environment with Pb soil concentrations up to 14,978±2270μgg −1 . An excess TM transfer has been evidenced in several stations, principally in two archaeological mining sites. Very high SET indices have been calculated for these two stations, and abnormal transfer was shown for a communal garden. The associated toxicological risk (ERITME index) is high and reflects the importance of investigating past contaminated sites, as is done for recent industrial sites. The use of these two indices highlights that the time elapsed since the deposition of TMs does not lead to TM immobilization, partly due to the acidic soil pH in all stations, which ranged from 3.7 to 5.7. The accumulation of TMs in snails was mainly modulated by the sources of exposure, i.e., soil, humus and vegetation, depending on the TM. The major influence of exposure sources on TM accumulation compared to the influence of soil characteristics may be due to the speciation of the TMs deposited several centuries ago and the importance of indirect transfers from vegetation and humus. Currently, signs of past mining activities in the valley have almost completely disappeared, but we show that their waste still presents a risk for environmental and human health. Highlights Past mining sites still represent a high risk for environmental health. SET and ERITME indices are adapted for risk assessment of past contaminated sites. On past mining wastes, silver appears as a significant contributor to the risk. Soil, humus and vegetation may all contribute to the transfer of trace metals. Graphical abstract [DISPLAY OMISSION]

    Abstract As cities represent the microcosms of global environmental change, it is very important for the global sustainable development by decoupling environmental pressure from economic growth on city level. In this paper, the municipality of Chongqing in China is employed as a case to show whether the decoupling of environmental pressures from economic growth has occurred in cities undergoing rapid economic growth; what is the level of decoupling; and what causes the observed degree of decoupling. Results show the following. (1) During the period of 1999–2010, decoupling from economic growth has been absolute for the emissions of SO 2 , soot, and waste water, while it has been relative for total energy consumption, emissions of CO 2 and solid waste. (2) Compared with the period 2000–2005, decoupling level improved for all the six environmental pressures in the period 2005–2010. (3) Compared with China and other three municipalities of China, the overall decoupling level of Chongqing is above China’s average while below those of Beijing and Shanghai. (4) During the period 1999–2000, technological change was the dominate factor for decoupling Chongqing’s environmental pressure from economic growth, as it contributed 131.4%, 134.6%, 99.9%, 97.7%, 104.5% and 54.9% to the decoupling of total energy consumption, emissions of CO 2 , SO 2 , soot, waste water and solid waste, respectively; while economic structural change had very tiny effect to the decoupling of emissions of soot and SO 2 , and it even had negative effect to that of total energy consumption, and emissions of CO 2 and waste water. Based on the above observations, we explain the difference in decoupling levels for different environmental pressures and suggest approaches for policy-makers on further promoting decoupling environmental pressure from economic growth. Highlights We explore the decoupling level of Chongqing during the period of 1999–2010. Decoupling is absolute for the emissions of SO 2 , soot and waste water in Chongqing. Technological change is the dominated driving force for decoupling in Chongqing. We explain the difference of decoupling level for different environmental pressures.

  6. [해외논문]   Are simple environmental indicators of food web dynamics reliable: Exploring the kittiwake–temperature relationship   SCIE SCOPUS

    Abstract This study examined the inter-relationships between kittiwake breeding success and sandeel abundance, Calanus copepods, chlorophyll and temperature. The validity of past proxies of sandeel prey ( Calanus and temperature) suggested in the literature was also examined. Winter temperature was not found to be a reliable indicator of the abundance of sandeel or lower trophic levels, although the present study did support past evidence for a dependence of kittiwake breeding success on local sandeel abundance as, with the exception of two years, there was a linear relationship with log age-0 sandeel abundance. The abundance of sandeel was positively linked to the dates of predicted peak egg abundance in C. finmarchicus and C. helgolandicus . This supported earlier evidence that the match with prey timing is important to sandeel recruitment. Neither Calanus species was associated with temperature in the February to March period nor in the April–May period, which may explain the lack of a temperature effect that propagates through the trophic levels. Consequently, although kittiwake breeding success appears to show some sensitivity and specificity to changes in their prey, this responsiveness was not found to extend to the lowest trophic level ( Calanus abundance) or to temperature. As such kittiwake breeding success was not a reliable indicator of climate-driven changes in the local food web.

    Abstract In recent years, China has experienced rapid economic development and thousands of people escaped from poverty. However, this high-speed development has also led to increased pressure on the environment. Although the Chinese government has focused on solving environmental problems for the past few decades, it appears to have had little effect. Environmental performance evaluation (EPE) is a quantifiable environmental management tool that can evaluate environmental protection effects and provide guidance to improve government efficiency. We use EPE to evaluate China’s environmental performance at the provincial level between 2006 and 2011. In this study, the theme framework and driver force-pressure-state-impact-response (DPSIR) framework models are used to build the composite index (CI) for environmental performance. This index includes 39 indicators in four categories that were selected based on data that can be acquired from China’s Statistical Bureau. The results indicate that the environmental performance index (EPI) of 30 provincial administrative regions (PARs) from 2006 to 2011 ranges from 44.12 (Shanxi, 2006) to 80.87 (Beijing, 2010), from poor to good, respectively. To help develop more effective policies to improve China’s regional environmental performance, cluster analysis (CLA) is applied to divide the 30 PARs into 3 sub-regions. Recommendations for improving the environmental performance of different sub-regions are made to help guide the Chinese government to adjust environmental governance approaches to local conditions.

    Abstract The utility and concordance of application of taxonomic-based (diversity, richness and composition) and functional-based (biological traits analysis and functional diversity indices) metrics to distinguish anthropogenic disturbance or stress gradients (e.g., nutrient enrichment) on intertidal rocky shores were explored using macroinvertebrate communities. Metrics from both approaches showed similar trends in the variation of communities along the gradients, in which higher ecological health was found in less disturbed sites (farthest from the disturbance source), with the converse at more stressful sites (close to the disturbance source). The functional-based approach, using biological traits analysis and functional diversity indices, showed potential to be included in monitoring programmes at rocky shores alongside taxonomic-based metrics. Highlights Macroinvertebrate metrics were compared within disturbance gradients. Taxonomic- and functional-based metrics showed similar trends along the gradients. The metrics showed higher ecological condition for less disturbed sites. Functional-based metrics showed potential to be included in monitoring programmes. Graphical abstract [DISPLAY OMISSION]

    Abstract A large amount of studies focuses on aquatic diatoms’ ecology and their use in the assessment of water quality. Little is known about terrestrial diatoms’ ecological behaviour and sensitivity to environmental factors. We hypothesise that terrestrial diatom communities can serve as a proxy of anthropic disturbance levels in terrestrial sites. To test our hypothesis, we apply an aquatic index to soil communities that is to deliver new information on the physiographic controls on soil diatoms. Diatom and soil samples were collected in the Attert River basin in Luxembourg during three seasons, in sites characterised by different combinations of geological, soil (schist, marl and sandstone) and land use (forest, grassland and agriculture) features. We found an effect of seasonality on soil diatom communities, reflected by different species dominance and abundances in samples during the three seasons. Soil pH and land use (which translates in a different amount of total carbon and nitrogen in soil) were identified as the variables having the largest impact in structuring the communities and as among the features with the highest importance in defining the ecological status of the sites (i.e. disturbed farmlands having higher pH and lower carbon and nitrogen content). However, the lack of information about the sensitivity of some of the most abundant terrestrial species in our study area caused some discrepancies between the expected (i.e. forested areas with low anthropic disturbance) and the obtained results, with several forested sites classified as having high anthropic disturbance. These results suggest that soil communities are likely to contain information about soil ecological status and highlight the importance of a better characterisation of terrestrial diatom species for developing a quality index based on soil communities. Highlights Sampling sites present different combinations of geology, soil type and land use. Soil pH and land use are main environmental controls on soil diatom communities. Index applied on soil diatoms to infer anthropic disturbance in each site. Sites with different land use show different disturbance levels. Understanding soil diatom ecology is key for the development of a soil quality index. Graphical abstract [DISPLAY OMISSION]

    Abstract Determining the equilibrium state of terrestrial carbon is a prerequisite for scientific analysis on the carbon cycle. However, the mechanism through which the carbon cycle reaches the equilibrium state remains unclear. Moreover, the carbon cycle in most of the short–term field experiments rarely reaches the equilibrium state. In this study, a detachable carbon cycle (DCC) model was proposed to simulate the equilibrium state of each carbon pool. The model was established based on a pool–and–flux scheme and contained 14 carbon pools, or carbon flow processes, each process could be detached from the main model and evaluated as an independent component. The environmental scalar algorithms of the Integrated Terrestrial Ecosystem Carbon budget model (InTEC) and Community Atmosphere Biosphere Land Exchange (CABLE) were incorporated in the DCC model. Four situations were compared using the two environmental scalar algorithms and model structure (9 vs. 14 carbon pools). Furthermore, the size and turnover time of each carbon pool were analyzed at the equilibrium state. A sensitivity analysis was then conducted to investigate the responses of carbon density and equilibrium time to 12 key parameters of the model. Results indicated that the combination of the CABLE environmental scalar algorithm and 14 pools exhibited improved performance on carbon storage simulation than that of the other combinations, and the effect of the environmental scalar algorithm was considerably larger than that of the carbon pool number. Sensitivity analysis indicated that the carbon density of grassland and cropland was more vulnerable and sensitive to key parameters of the model than that of the other biomes. This study elucidates influencing factors and underlying control mechanisms in the carbon accumulation, and provides a framework for quantitative analysis of each component of the carbon cycle. Highlights Each of the carbon pool or carbon flow process was detached from the main model as independent component for study. NPP and ξ are the most important parameters in the DCC model. The carbon density of GRA and CRO is more sensitive to key parameters of the model than that of the other biomes.
