Rapid urbanization has affected ecosystem stability, and the construction of ecological security patterns (ESPs) can rationally allocate resources achieve protection. Priority evaluation critical areas maximize benefits protection, which is crucial for sustainable urban development. However, most prior studies have focused on assessing individual elements ESP, rarely considering both protection priority sources corridors. We constructed ESPs Wuhan Metropolitan Area (WMA) from 2000 to 2020 evaluated corridors The findings indicated that high-level exhibited higher overall landscape connectivity service values with lower patch fragmentation. average area proportions primary, secondary, tertiary in 2000, 2010, were 41.11%, 23.03%, 29.86%, respectively. High-level had shorter lengths offered comprehensive values. total length secondary exceeded primary by 1951.19 km, 650.39 2238.18 km 2020, Primary corridors, connected fragmented isolated sources, should their land percentage increased enhance connectivity. Secondary two independent distant providing basis intervening area, whose surrounding habitats be protected. This study identifies offers a theoretical practical reference balancing development

In addressing global climate change and promoting economic growth, achieving a comprehensive carbon balance at the county level is vital for sustainable development. However, most studies focus on between emissions sequestration (CESB), neglecting intricate ecological (EECB) this scale. This study introduces an analytical framework that couples development with protection by using coupling coordination degree analysis, zoning, Markov-PLUS model. Taking Jiangxi Province as case study, we evaluate spatio-temporal dynamics of from 2000–2020 predict future trends 2030 under four potential scenarios. Results reveal significant regional variations in CESB over two decades, which primarily exhibit net emission. Meanwhile, continuous decline EECB highlights need balanced By 2030, land use's capacity expected to increase different scenarios, leading 'middle-high, sides-low' spatial pattern CESB. These findings are crucial policymakers devising strategies

With global climate change and irrational human activities, regional water resource conflicts are becoming more pronounced. The availability of in watersheds can be indicated by the yield. Exploring factors that influence yield is crucial responding to protecting resource. Previous research on influencing has frequently adopted a macro-level perspective, which failed reflect mechanisms changes at local scale adequately. Therefore, this study proposes novel framework for integrally evaluating impacts activities services from both perspectives. Taking Ganzhou City, source Ganjiang River, as an example, results show following: (1) City had largest 1307.29 mm 2016, lowest was only 375.32 2011. spatial distribution pattern mainly affected surface environment, high-value regions area were predominantly located urban areas with flat terrain. (2) At scale, where contribute than 80% accounted 25% area. In comparison, impact 0.95%. contribution rate significantly greater change. (3) simulation four scenarios contributed (>98%) yield, higher (<2%). This puts forward pioneering views driving forces provides valuable theoretical basis protection ecological environment construction.
