Construction and Optimization of Ecological Security Patterns in Key Ecological Function Areas:a Case Study of Taihu County
摘要
Abstract
The construction of county-level ecological security patterns plays a crucial role in key ecological function areas,serving as a cornerstone for advancing national ecological civilization and ensuring regional ecological security.Traditional construction approaches often overlook the precise identification of"critical nodes"with significant ecological attributes and exhibit ambiguity in the setting of ecological flow parameters,which hinders the accurate depiction of the ecological value characteristics of counties.Taking Taihu county as a case study,a combination of Morphological Spatial Pattern Analysis(MSPA),Minimum Cumulative Resistance(MCR),and Circuit Theory spatial econometric models are used to identify ecological sources,extract ecological corridors,and determine critical ecological nodes,thereby achieving a visual simulation of the ecological security pattern.The results indicate:26 ecological sources are concentrated in the northwest and southeast of the study area,with 75 ecological corridors and 53 ecological nodes constructed.Based on ecological elements and the territorial spatial planning of Taihu county,an ecological security pattern of"three centers,two zones,three axes,two corridors,and multiple nodes"is established.Two optimization pathways are proposed:"prioritizing natural protection to reduce human interference"and"balancing natural protection with ecological restoration."The integrated spatial econometric model combines the strengths of various models,fully considering biodiversity flow and precisely identifying critical ecological nodes,providing valuable insights for enhancing the ecological resilience of similar key ecological function areas.关键词
