基于地理探测器的神府矿区生境质量时空特征及驱动机制分析
Spatial-temporal characteristics and driving mechanisms analysis of habitat quality in Shenfu mining area based on geodetector
摘要
Abstract
The ecological environment in the western mining areas of China is fragile,with coal resources being abundant.Large-scale development activities have caused a series of ecological and environmental problems.Quantitatively evaluating the spatiotemporal evolution of the habi-tat quality will be of practical significance for the protection of ecological environment and healthy sustainable development in our country's mining areas.Taking the typical mining area of Shenfu in the western region as an example,this article uses the InVEST model and couples it with the geographic detector to analyze the changes in habitat quality in the mining area from both the o-verall perspective and different mining intensities,with the reasons for the spatial heterogeneity of habitat quality explored.The results show that:①The overall habitat quality in the Shenfu mining area is good,with the habitat quality type of good accounting for about 50％of the total area.②From 2005-2018,the average habitat quality of the study area has increased from 0.496 8 to 0.510 6 and then decreases to 0.470 7,showing a trend of initial increase and subsequent de-crease.③Different levels of mining intensity have different effects on habitat quality.The rate of change in habitat quality in low and medium mining intensity areas are as high as 265.12％and 173.21％,respectively,far higher than that in high and extremely high mining intensity areas and non-mining areas.④The main reason for the change of habitat quality in the study area is the synergy of natural factors and human factors,among which the greatest determining force is the synergy of population and NDVI,which is 0.163 7.关键词
