夹金山脉大熊猫栖息地生境质量与人类活动强度耦合协调研究
Coupling and Coordination of Habitat Quality and Human Activity Intensity in Jiajin Mountains Giant Panda Sanctuary
摘要
Abstract
As the intensity of human activities increases daily,it causes a decline in habitat quality in nature reserves and the gradual loss of wildlife habitats.The giant panda habitat in the Jiajin Mountain Range is rich in biodiversity,and cont ains rare and endangered species.Contradictions between humans and land are prominent,and biodiversity is a serious thr eat.Studying the response of habitat quality to the intensity of human activities and exploring the coordinated coupling sta te between them is of great significance for understanding the survival status and threats to species,and for judging the e ffectiveness of management.This study is based on Landsat images from 2001,2009,2016,and 2021 combined with mult i-source remote sensing data.It utilizes the Human Footprint Index to measure the intensity of human activities,and the I nVEST model to assess habitat quality.Using the Geographically Weighted Regression model and the Coupling Coordinati on Model,this study measured the response of habitat quality of the Giant Panda Habitat in the Jiajin Mountains to huma n activity intensity and the coupling coordination relationship between them.The findings indicate the following.1)From 2001 to 2021,the Human Footprint index exhibited a polarization trend.The range of high Human Footprint index values expanded from 0.11%to 0.29%,whereas the distribution range of low Human Footprint index values decreased from 69.4 3%to 60.12%.2)During the same period,the average rate of habitat quality from 2001 to 2021 was 0.03%and the ove rall habitat quality fluctuated slightly,with higher and high-quality habitats accounting for over 62%of the area.Spatially,this presented a pattern of being low in the middle,high around the edges,and low at the periphery of the ring-like distr ibution.3)From 2001 to 2021,regions that were positively and negatively affected by human activity intensity remained r elatively fixed.Notably,the proportion of areas showing positive correlations(58%)surpassed that of the areas showing n egative correlations(42%).However,the negative effects were more pronounced.4)Between 2001 and 2021,the relations hip between human activity intensity and habitat quality was characterized as"high coupling and primary coordination",wi th a spatial pattern of being low in the middle and high around the edges.This study can inform the scientific manageme nt and control of human activity ranges,facilitate the coordination of human activity spaces and ecological spaces,and ser ve as a reference for the ecological environment assessment and management of nature reserves.关键词
