Identification,construction and optimization of Ma'anshan city urban green space ecological network
摘要
Abstract
[Objective]This study aimed to address the ecological network planning needs of rapidly urbanizing regions.[Method]A methodological framework integrating"ecological source identification,ecological corridor extraction,ecological node optimization,ecological network construction,and ecological network refinement"was developed through combining morphological spatial pattern analysis(MSPA),the minimum cumulative resistance(MCR)model,landscape connectivity indices,the gravity model,circuit theory,and network structural metrics.[Result]The results of the empirical study in Ma'anshan city,Anhui Province demonstrated that the green space eco-logical network of Ma'anshan city comprised 18 core ecological source sites,65 ecological corridors and 21 ecologi-cal nodes.After optimization by incorporating stepping-stone patches,the network closure index(α index),network connectivity index(β index),and network connectivity index(γ index)increased from 1.55,3.61,and 1.35(pre-optimization)to 2.45,5.47,and 1.95(post-optimization),respectively,indicating significantly enhanced connec-tivity;targeted optimization strategies were proposed based on the structural characteristics of Ma'anshan's ecologi-cal network.[Conclusion]This study provides theoretical and practical insights for optimizing green-space ecologi-cal networks and advancing ecological conservation in Ma'anshan and other rapidly urbanizing areas.关键词
