Abstract With the aggravation of environmental conflicts, exploring green development path is an inevitable choice to alleviate land tension, guarantee harmony human–land relations, and promote coordinated regional development. The Yellow River Basin (YRB) important national ecological barrier area, but impact its problems can no longer be ignored. Ecological security patterns (ESPs) provide remarkable means for identification, configuration, optimization spaces, which help people identify most central zone that needs protected. In this paper, we proposed strategies applicable YRB as a case area. Firstly, basic framework ESPs was constructed based on “three‐step” method, where sources were delineated by importance/sensitivity, resistance surfaces created entropy weight distribution ranges corridors, nodes, barriers confirmed circuit theory. Meanwhile, stepping stones introduced optimize ESPs, obtained through hotspot analysis buffer analysis. results displayed (1) covered area 166,699.32 km 2 , occupying 21% basin They widely distributed in upper middle junctions, southeast east basin, types make up them, cropland, woodland, grassland account 97.6%.

This study focuses on constructing a heritage corridor for traditional villages in the Taihu Lake region, aiming to promote cultural preservation and sustainable development of these through innovative pathway design. Based spatial distribution characteristics across five cities surrounding (Suzhou, Wuxi, Changzhou, Huzhou, Jiaxing) existing transportation network, this research integrates Circuit Effective Conductance (CEC) theory with ArcGIS analysis methods optimize pathways corridor. The results show that expected nearest neighbor distance 307 region is 5245.61 m, actual being 3385.60 z-score −11.85, index 0.645786, indicating exhibit clustered distribution. Combined kernel density results, “dual-core–four zones–multiple scatter points” structure revealed, Dongshan Island Wujiang District serving as primary secondary cores, respectively. By establishing “dual-ring corridor” stable village transmission has been formed, consisting 137 corridors. Meanwhile, CEC model demonstrates high adaptability generating circular corridors, particularly creating closed-loop structures around lake, thereby enhancing connectivity corridors facilitating effective flow resources. Through strategic design outer inner ring successfully links develops optimal travel routes. provides practical solutions protection, revitalization, integration tourism offers new perspective lakefront geographies China.
