Human activities have a significant impact on global ecosystems. Assessing and quantifying ecological vulnerability is fundamental challenge in the study of ecosystem’s capacity to respond anthropogenic disturbances. However, little research has been conducted EVA’s existing fuzzy uncertainties. In this paper, an assessment (EVA) framework that integrated Exposure-Sensitivity-Adaptive Capacity (ESC) framework, method, multiple-criteria decision analysis (MCDA), took into account human impacts, was developed address uncertainties process. For first time, we provincial-scale case China illustrate our proposed methodology. Our findings imply China’s spatially heterogeneous due regional differences exposure, sensitivity, adaptive indices. The results cause can provide guidance for further decision-making facilitate protection quality over medium long term. EVA also be duplicated at multiple spatial temporal dimensions utilizing context-specific datasets assist environmental managers making informed decisions.

Ecological security is essential for the development of environmental health and human society. However, driving mechanisms spatial non-stationarity ecological risks are still unknown, particularly in arid areas. Thus, this study constructed an risk index (ERI) research framework areas based on land use socio-economic data from 1980 to 2020 investigate spatiotemporal evolution trend, mechanisms, predict under business-as-usual, economic development, protection scenarios using a patch-generating simulation (PLUS) model. The results show that: (1) cropland build-up were expanding, whereas forestland grassland water bodies shrinking. Compared with two stages 2000 2020, increased by 4.73% 51.52%, respectively, 12.64% 106.52%, indicating rapid drastic changes past 20 years. (2) With change landscape diversity, regional showed increasing future trend because cumulative effect pattern caused activities. (3) Moreover, dramatic risk, intense activity land, agricultural artificial oases, mountainous Corresponding analysis population, GDP, distance government, water, primary roads; have significant DEM has direct indirect paths. Ultimately, proposed can present their influencing which help develop sustainable policies.

Coastal wetlands are located at the intersection of land and sea provide extremely important ecological services. The coastal estuarine harbors representative parts wetlands. Changes that occur in harbor microcosms changes occurring more generally. Hainan Island, China, typical tropical islands sensitive to climate change. In context global level rise, studying characteristics spatial temporal distribution on as well their vulnerability, could scientific technological support address adverse effects Using nine target areas, this study systematically studies spatial–temporal evolution Island from 1990 2020. results suggest following: (1) total area has remained relatively stable, but artificial wetlands, especially aquaculture ponds, increased significantly. There is a clear variability mangrove with increase areas high degree protection, such Dongzhai Harbor (DZG). intensity human activity been significantly reduced, Bamen Bay (BMG). (2) overall risk low, average wetland index (WRI) all being below 0.15. higher lower area, DZG. Human activities main factor causing (3) Climate-change-induced rise intensification determinants future trends ecosystem stability. guidance conservation restoration

Increased groundwater exploitation can cause severe depletion and may trigger geological hazards such as wetland degradation. The Xiong’an New Area is an important deployment of the national strategy to promote coordinated development Beijing-Tianjin-Hebei region. protection wetlands will play ecological role in socio-economic Area. This paper proposes improved catastrophe theory (ICT) combined it with analytic hierarchy process (AHP) entropy weight method (EWM), labelled AHP-EWM-ICT method. was applied evaluate evolutionary trend degradation risk from 2000 2020. Results showed that, first, fluctuating upward, increase 80.17% 2020 compared 2000. level increased ‘Very low’ ‘Medium’ 2020, most years at during 21 years. Second, Rongcheng County, which has higher intensity extraction well per capita GDP Xiong County Anxin contributed stress degree values progressed northwest southeast. Third, due implementation recharge, Baiyangdian shown a first increasing then decreasing. Fourth, be more than other northern China. In addition implementing replenishment projects, government should also pay attention functional restoration reduction sources areas surrounding wetlands.

Assessing the landscape ecological risk (LER) will facilitate optimal planning of land-use patterns and mitigating regional risks, especially in megacities under rapid urbanization. And selecting appropriate spatial analysis scales is prerequisite for accurate assessment LER. In this study, we demonstrate spatio-temporal dynamics LER by determining Beijing, China from 2000 to 2020. The results indicate that a granularity 50 m magnitude 5 km are assessment. study area had predominantly medium with medium, high higher risks accounting approximately 70% revealed was at level. Fortunately, decreased 14.64% while low lower increased 16.62% over past two decades, which indicated on general downward trend. pattern varies east west, clustered northeast southeast city center, gradually dispersing elsewhere. contrast, were center western regions, expanding outward center. built-up land cropland central city, but relatively areas away it. urban fringe dominated woodland grassland exhibited differentiation spatially correlated expressways significant changes observed adjacent expressways. Specifically, expansion occurred along ring roads typical case primarily enclosed fifth road expanded towards near sixth Moreover, manifests obvious agglomeration influenced human disturbance, apparent high-high low-low agglomerations. It suggested implement optimization enhancing diversity connectivity effectively mitigate risks. These findings provide scientific reference researches aimed fostering high-quality sustainable development metropolitan areas.

Alpine grassland is one of the most fragile and sensitive ecosystems, it serves as a crucial ecological security barrier on Tibetan Plateau. Due to combined influence climate change human activities, degradation alpine in Gannan Prefecture has been increasing recent years, causing increases risk (ER) leading ecosystem facing unprecedented challenges. In this context, particularly construct potential damage index (PGDI) assessment framework that can be used effectively characterize ecosystem. This study comprehensively uses multi-source data PGDI based resilience index, landscape ER grass–livestock balance index. Thereafter, we proposed feasible for assessing comprehensive analyzed responsive relationship between services (ESs) grassland. There are four findings. The first from 2000–2020 had low distribution southeast high trend northwest, with medium (29.27%) lower (27.62%) dominating. high-risk area accounted 4.58% was mainly Lintan County, border Diebu Zhuoni Counties, eastern part Xiahe southwest Hezuo. Second, ESs showed pattern northwest southeast. only 9.30% studied were distributed west Maqu County central County. Third, Moran’s values 2000, 2005, 2010, 2015, 2020 −0.246, −0.429, −0.348, −0.320, −0.285, respectively, thereby indicating significant negative spatial autocorrelation all aspects. Fourth, caused by action multiple factors. differences driving factors affect ER. Landscape dominant factor affecting ER, q greater than 0.25, followed DEM NDVI. addition, interaction diversity NDVI greatest impact Overall, offers new methodological quantification grasslands.
