基于VSD模型的黄山市生态系统脆弱性评价及时空演变分析
Ecological system vulnerability assessment and temporal-spatial evolution analysis of Huangshan city based on VSD model
摘要
Abstract
Scientific assessment of ecosystem vulnerability is essential for regional ecological conservation and high-quality devel-opment.Taking Huangshan City's three districts and four counties as a case study,this research developed an evaluation framework based on the VSD model through three dimensions-exposure,sensitivity,and adaptability.It comprehensively assessed regional ecologi-cal vulnerability from 2014 to 2023 and analyzed its spatiotemporal evolution and influencing factors using ArcGIS and the obstacle de-gree model.The results showed that:(1)During 2014-2023,Huangshan's ecosystem vulnerability exhibited a"first increase then de-crease"trend,remaining moderately vulnerable overall;factors affecting the vulnerability index(in descending order of influence)were exposure,sensitivity and adaptability.(2)Temporally,slightly vulnerable areas increased by 40.3％,while moderately/severely vulner-able areas decreased(severe vulnerability eliminated in 2023);however,Tunxi District remained extremely vulnerable due to rapid ur-banization,a key ecological governance area.(3)Spatially,the vulnerability presented a"west-low,east-high"pattern.(4)During 2014-2023,exposure's obstacle degree rose,sensitivity's fluctuated,and adaptability's fell.Based on these findings,measures such as enhancing ecological monitoring and assessment,implementing differentiated protection strategies,and improving ecological compensa-tion mechanisms were proposed.关键词
