“…ESV is the basis for city governments to make environmental protection, ecological red line delineation, and ecological compensation 13 . Currently, valuation methodologies used to compute ESV are primarily based on the unit area values factor method [14][15][16] , which monetizes the many services supplied by diverse ecological processes. Another method is based on the assessment of ecological service functions, such as water production, carbon sequestration and biodiversity 13,17,18 .…”

Ecosystems in winter cities are complex and fragile, experiencing significant changes due to climate variations and human construction activities. Assessing the ecological status and risk faced by these areas commonly involves using Ecosystem Service Value (ESV) and Ecological Risk Index (ERI). However, limited research has combined these two measures to reveal sptial-temporal trends in urban ecosystem conditions. This study utilizes land use data from 2000, 2010, and 2020 to construct ESV and ERI measurement models using the improved unit area value factor method and landscape pattern index method, respectively. By evaluating the regional and temporal differentiation features of ESV and ERI, in addition to their spatial association, the study identifies priority areas for urban ecological restoration and recommends rationalization solutions. The findings indicate: Between 2000 and 2020, Shenyang's total ESV decreased by 1.31%, from 273.97×108 CNY to 270.38×108 CNY. The ESV per unit area dropped from 21304.50 CNY/hm2 to 21025.33 CNY/hm2. The ecological risk to the study area has increased. The area of ERI high-value, higher-value, and medium-value zones remained relatively stable, while the area of low-value zones decreased by 12.78%, and the area of lower-value zones increased by 13.21%. There is a spatial correlation between ESV and ERI in winter cities. The H-H area is distributed in the northeastern hilly region, which exhibits strong ESV supply capacity while facing severe ecological risks, identifying it as a priority region to pursue ecological rehabilitation. These results offer theoretical justification for urban management and planning, guaranteeing the ecological security and sustainability of winter cities.

Wetlands are among the most important habitats of highly wetland-dependent waterbirds but are subject to ongoing habitat loss and degradation owing to intensified anthropogenic activities. The scarcity of human and natural resources makes effective habitat protection an important concern. Here, we aimed to investigate waterbird habitat protection methods for Anhui Province, China, a critical stopover and wintering area on the East Asian-Australasian Flyway that features rich wetland resources subject to significant habitat loss and degradation. We evaluated the status and importance of 306 wintering waterbird habitats and identified the key environmental influences and current protection gaps using the entropy weights method and generalized additive modeling. We found 73 important habitats for waterbirds in Anhui Province, which were classified into levels of importance (descending from I to V) according to the natural discontinuity method. Level I and Level II habitats were mainly located in the Yangtze River floodplain and Level IV habitats in the Huaihe River floodplain. The gap analysis showed that 42 important waterbird habitats had protection gaps, accounting for 57.53% of the total area. Waterbird habitat importance was significantly correlated with elevation, normalized vegetation index, lake area, and lake circumference but not with distance from roads or population density. The results of this study provide scientific information for waterbird habitat conservation planning, which is crucial for maintaining wetland ecosystem functions.
