黄土高原矿区生态系统服务价值的时空变化
Spatiotemporal changes of the ecosystem service value for mining area in Loess Plateau:A case of Pingshuo mining area
摘要
Abstract
Spatiotemporal changes in ecosystem service value are crucial for protecting the ecological environ-ment and enhancing the ecosystem functionality within mining areas.Based on remote sensing and land-use data,ecosystem service value(ESV)was quantitatively analyzed in the Pingshuo mining area of the Loess Plateau of China from 1990 to 2020 using the 3S(GIS,RS,GPS)technique,a standard equivalent method,and ecological contribution rate.The results showed the following facts:(1)Shifts in land-use type from 1990 to 2020,notably the most substantial decrease occurring in farmland(1122.72 hm2)and a corresponding increase in built-up land(2044.23 hm2)to its highest.(2)A decline in total ESV from 19562.43×104 Yuan in 1990 to 11265.40×104 Yuan in 2010,primarily attributed to reduced ESV in built-up land and grassland.However,a subsequent increase to 15755.47×103 Yuan in 2020 was observed,which was attributed to the implementation of ecological programs.(3)Varied decreases in individual ESV components,with water retention,purified environment,and biodiversity values decreased by 115.84%,69.92%,and 18.29%,respectively,over 1990-2020,excluding soil retention,which remained constant.(4)ESV spatial distribution in the Pingshuo mining area,exhibiting higher values in the north/south and lower in the middle.(5)Ecological contribution rates of grassland,built-up land,and forestland in 1990-2020,standing at-41.52%,-34.49%,and-10.09%,respectively.These factors emerged as the main contributors and sensitive elements in the Pingshuo mining area.关键词
