基于SRP模型的塔里木胡杨林公园生态脆弱性研究
Ecological vulnerability assessment of Tarim Populus euphratica Forest Park based on SRP model
摘要
Abstract
An ecological vulnerability assessment provides the foundation for sustainable regional development and restoration.This study utilized remote sensing data and socioeconomic statistics to construct an ecological vulnerability evaluation index system for the Tarim Populus euphratica Forest Park(Xinjiang,China).Based on the sensitivity-resilience-pressure model,the system incorporated 18 indicators,including ecological function,and was analyzed using a combined hierarchical analysis-entropy weighting method.This approach revealed the spatiotemporal characteristics and driving factors of the park's ecological vulnerability from 2000 to 2020.The results are as follows:(1)The park's average ecological vulnerability index was 0.30 in 2020,indicating a mild vulnerability level,with a spatial distribution of higher vulnerability in the eastern,western,and central areas and lower vulnerability in the southeast.(2)The park's ecological vulnerability showed a fluctuating downward trend,moving from an index of 0.33 in 2000 to 0.47 in 2010,before improving to 0.29 in 2015 and then slightly degrading to 0.30 in 2020.Over this period,44.52%of the area saw a decrease in vulnerability,while 28.60%ex-perienced an increase.(3)A significant positive spatial correlation was consistently observed,with a Global Moran's I greater than 0(Z>2.58,P<0.01),indicating prominent low-low and high-high clustering.(4)Key sin-gle-factor drivers of vulnerability included the degree of water change,desertification,water conservation,and the vegetation index.The interactions among the factors demonstrated a non-linear and two-factor enhancement relationship.Remarkably,the synergistic effect between the degree of water change and water source conserva-tion was the most significant driver of the park's ecological vulnerability.These results offer a scientific refer-ence for the ecological restoration,environmental protection,and sustainable management of the Tarim P.euphra-tica Forest Park.关键词
