The Giant Panda National Park (GPNP) and its surrounding areas constitute a comprehensive ecosystem aimed at protecting the natural habitat of giant pandas, maintaining biodiversity, ensuring ecological balance. Investigating spatial correlation between landscape pattern indices sensitivity (ES) in this area is crucial step construction civilization contributes significantly to conservation, restoration, environmental management. This study utilized Geographic Information Systems (GIS) Fragstats software select nine evaluation factors four comprehensively evaluate ES patterns GPNP areas. discovered that substantially higher than neighboring areas, with northern Qionglai Mountain western Minshan showing highest concentrations exceptionally high sensitivity. Highly sensitive account for 35.22% region, concentrated within national park, except Qinling area, as well southern distribution moderately more uniform, while low insensitive are found primarily eastern along park’s environs. Patch density (PD) lower PD central parts. division index (DIVISION) decreases from west east, disturbance (LDI) park small LDI entire region. Moran’s analysis shows positively correlated (PD, SPLIT, DIVISION, LDI), strongest DIVISION Spatially, internal have but sensitivity, region exhibits severe fragmentation. Major clusters values around Qionglai-Daxiangling indicating these complex structures, numerous edges, significant impacts on biodiversity processes.

Conducting ecological sensitivity assessment is a crucial approach for pinpointing regional environmental issues, which can offer scientific basis to aid in the prevention of degradation and ensuring security. With protection high-quality development Yellow River Basin (YRB) at level national strategy China, there critical need comprehensive YRB's sensitivity. To this end, study aimed construct new evaluation index system from three perspectives: natural ecosystem, natural-social social ecosystem. The was quantified using entire-array-polygon indicator method, spatiotemporal changes YRB its sub-basins were analyzed 2000 2020. optimal parameters-based geographical detector model employed delve into mechanisms driving spatial variation We found that (1) 2020, exhibited bimodal trend. Spatially, it tended be low western eastern parts while relatively high southern central regions. (2) displayed notable clustering effects terms source area showed both "high-high" "low-low" groupings, upstream predominance clusters, midstream downstream demonstrated by concentrated clusters. However, effect gradually weakened over time. (3) primarily driven factors like shifts climate change soil erosion. There also marked differences heterogeneity across different sub-basins.

Rapid urbanization has put the marine environment under great threat, and cities in Bay Bottom area are more likely to cause a large number of ecological problems urban development construction due their special land-sea interaction environment. Ecological network is an effective solution coordinate regional protection sustainable development. This study focused on Chengyang District, one highly urbanized areas at bottom Jiaozhou Qingdao, China, was using Morphological Spatial Pattern Analysis (MSPA) initially identify source extracting important conjunction with landscape connectivity assessment, determining resistance values based importance ecosystem services, optimizing by minimum cumulative model (MCR) structure analysis. The results indicated that: (1) habitat District severely fragmented, significant features terms area, type corridor distribution, low percentage identification characteristic types such as reservoirs, wetlands, aquaculture ponds, while corridors concentrated rivers bays, there fragmentation inland city. (2) Preliminarily, 15 sites were identified, mainly distributed vicinity Wetland, Jihongtan Reservoir Laoshan Mountain, among which, Wetland most District. Thirty-two nodes 24 constructed. (3) By increasing sources optimized forms spatial pattern "four cores, three belts, four districts", proposes formulates targeted management strategies promote bay. In addition, this provides new reference for global bay improving area.

China’s urban development has reached a stage where green sustainable must be considered. Constructing an ecological security pattern (ESP) can effectively contribute to maintaining and safety in city. Harbin, significant city northeastern China, serves as the study area with focus on its central district. To construct optimize Harbin’s ESP, this utilized sensitivity assessment, MSPA (morphological spatial analysis), gravity model, landscape connectivity MCR (minimum cumulative resistance) model identify source areas, corridors, nodes. Research reveals that there are 23 areas within area, primarily situated along Songhua River mountain woodlands of A-cheng District. This identified 48 predominantly Daowai District, eastern part Xiangfang Among these, 8 deemed 10 important connecting corridors. We propose structure optimization, referred “two axes, two belts, four areas”, present corresponding management recommendations. The analytical framework provides valuable method for constructing patterns selecting at regional scale Harbin City, particularly complex plain areas.
