As urban spaces expand, changes in land use significantly affect the structure and function of ecosystems, particularly with challenges such as green space reduction uneven distribution. This study focused on central area Chengdu, China, simulating forecasting various development scenarios for 2035, including cultivated protection (CP), economic (ED), ecological priority (EP), natural (ND). The construction networks followed a systematic process, incorporating key methods source identification, landscape resistance surface construction, corridor extraction. connectivity these was assessed using syntax. results indicated that: (1) Construction expanded across all scenarios, ED scenario having largest area, while EP resulted significant increase space. (2) Ecological corridors were established under every scenario, featuring most extensive well-connected network, linking patches surrounding areas. (3) scenario’s network displayed integration, choice, connectivity, depth values that indicate complete stable structure. provides comprehensive analysis different strategies, offering valuable insights optimizing planning management.

Constructing a Composite Ecological Security Pattern Through Blind Zone Reduction and Ecological Risk Networks: A Case Study of the Middle Yangtze River Urban Agglomeration, China

Sustainability, Journal Year: 2025, Volume and Issue: 17(11), P. 5099 - 5099

The Middle Yangtze River Urban Agglomeration, a critical ecological barrier in China, faces escalating pressures from rapid urbanization and climate change, leading to fragmented landscapes degraded ecosystem services. To address the synergistic challenges of protection risk management, this paper takes urban agglomeration middle reaches as study area, obtains source patches through morphological spatial pattern analysis. Based on distribution risky areas, blind zones are cut down by optimizing buffer merging patches. Finally, composite network is constructed circuit theory superimposed dual method. results showed that (1) there 16 area. Six complementary sources four new were obtained zone reduction strategy. percentage reduced 58.4% 39.5%. (2) integrated nodes with 11,366 connecting edges identified. distributed around central Jiuling-Mafushan Mountains, mainly western southern areas Dongting Lake Plain. (3) Primary integration for stability, 75% node failure threshold triggering systemic collapse. proposed strategy “mountain protection–plain control–railway monitoring” consistent China’s territorial planning. By incorporating into conservation framework, provides feasible insights balancing development sustainability ecologically fragile areas.
