Analysis of spatial-temporal variation and driving factors of ecological quality in typical mining areas of Daye City
摘要
Abstract
Mastering the spatial IRSEtemporal variations of ecological quality in mining areas and the mechanism of driving factors is of great significance for the sustainable development of mines.Taking Daye City as an example,Two Landsat images from 2000 and 2019 were selected as the basic data sources.The improved remote sensing ecological index was used to evaluate the ecological quality and evolution characteristics of typical mining areas in Daye City.The geographic detector model was used to comprehensively analyze the interaction relationships between eight driving factors,including natural and human factors;On this basis,single factor analysis was conducted on mining activities,roads,and land use,respectively.The results show that:①In 2000 and 2019,the remote sensing ecological index(IRSE)of typical mining areas in Daye City is 0.59 and 0.63,respectively.The overall ecological quality changed from intermediate to good,and the spatial distribution of ecological quality show significant differences.The proportion of ecological quality grades of excellent and poor is increasing;②In general,land use,elevation,and residential areas are the dominant factors in the spatial heterogeneity of ecological quality distribution in the study area,and there is a dual factor or nonIRSElinear enhancement among the driving factors;From the local perspective,roads and mining activities have the significant negative impact on the surrounding ecological quality,and the degree of impact is increasing;③The geographical weighted regression analysis has a better fitting degree than ordinary univariate linear regression,and when the kernel density estimation(EKD)of mining land is greater than or equal to 0.2,the research scope includes the mining area and a certain buffer zone around it.At this time,the fitting degree and correlation coefficients of mining land EKD with IRSE and ΔIRSE reach their maximum values,indicating that mining land will have the significant impact on its own and surrounding ecological quality;④The impact of roads on the surrounding ecological quality exhibits similar gradient changes,with the comprehensive impact threshold of around 750 m;⑤From the perspective of land use change,the deterioration of ecological quality is mainly due to the expansion of urban and mining areas,the addition of new roads,and the transfer of cultivated land to impermeable layers.The improvement of ecological quality is mainly due to the conversion of farmland to forests and grasslands,and the abandonment of some cultivated land,which leads to its transfer to shrubs.关键词
