基于MSPA模型和电路理论的南京都市圈生态安全格局构建
Construction of Ecological Security Pattern Based on MSPA and Circuit Theory in Nanjing Metropolitan Area
摘要
Abstract
This study investigates the Nanjing metropolitan area to identify ecological source areas by integra-ting ecosystem service importance evaluation,MSPA model,and landscape connectivity assessment.Based on the constructed resistance surface,ecological corridors,ecological pinch points,and ecological obstacle points were i-dentified and extracted using circuit theory.Ultimately,an ecological security pattern was constructed,and differ-entiated management strategies were proposed.The results show that there are 23 ecological sources in Nanjing met-ropolitan area,with a total area of 7 886.21 km2.The overall distribution is characterized by clustering in the southern part of the city and sparsity in the central and northern parts.A total of 53 ecological corridors were identi-fied,comprising 47 important and 6 general.The distribution is characterized by a spiderweb-like pattern,with higher concentrations in the south and lower concentrations in the north-central region,with an undulating north-south extension.A total of 247 ecological pinch points,covering an area of 332.65 km2,were identified in the mid-dle of the Nanjing Metropolitan Area.Additionally,211 ecological obstacle points,covering an area of 688.05 km2,were predominantly distributed in the central and southern regions of the Nanjing Metropolitan Area.An ecological security pattern and zoning control strategy for'One Belt and Three Zones'was established,comprising the Yangtze River Ecological Protection Belt,Ecological Buffer Zone,Ecological Restoration Zone,and Ecological Conservation Zone.This study provides a new case study for constructing a regional ecological security pattern and offers scientific recommendations for zoning control and ecological protection of the pattern within the Nanjing metropolitan area,which is of great significance for ensuring regional ecological security.关键词
