基于SRP模型的哈尔滨市生态脆弱性评价
Ecological vulnerability evaluation of Harbin City based on SRP model
摘要
Abstract
This paper aims to establish a reasonable ecological vulnerability assessment system.Based on the"Sensitivity Resilience Stress"model(SRP model),the study consists of selecting 15 indi-cators to construct an evaluation system,determining the weight of each indicator by using spatial princi-pal component analysis,analyzing the changing and clustering characteristics of the ecological vulnerabili-ty in Harbin City from a spatiotemporal scale,and exploring its driving factors through geodetector.The results showed that from the year 2000 to 2020,the overall level of ecological vulnerability in Harbin was relatively low,mainly mild and micro degrees.The hot spots of high and low ecological vulnerability are distributed in the northern,central and southeastern regions.The ecological vulnerability of the central and eastern regions,which account for 53.63%of the total area,decreases and the stability of the eco-logical environment increases.Net primary productivity and biological abundance index are the two driv-ing factors of ecological vulnerability.The overall ecological vulnerability of Harbin has improved over the past 20 years,with only six western districts experiencing deterioration.This result can provide reference for ecological protection and restoration work.关键词
