黄土山丘区土地利用变化对生态系统服务价值的影响——以长河流域为例
Effects of Land Use Change on Ecosystem Service Value in the Loess Hilly Area——A Case Study of the Changhe River Basin
摘要
Abstract
We analyzed the characteristics of land use change by using mathematical model on the basis of the remote sensing data of the Changhe River Basin from 2005 to 2015,then,according to ecosystem services value evaluation model,we quantitatively analyzed the impact of land use type on ecosystem services value in theChanghe River Basin.The results showed that:(1) from 2005 to 2015,the area of cultivated land decreased gradually,while construction land increased gradually,woodland,grassland,water area increased first and then decreased;cultivated land was mainly turned into grassland and construction land,construction land expansion was mainly from cultivated land and grassland.(2) The total value of ecological services of land use change in the Changhe River Basin decreased from 2005 to 2015,and its ecological service value decreased from 3.509× 107yuan in 2005 to 3.485× 107yuan in 2015,or reduced 2.4× 105yuan;the ecosystem service value of water conservation,entertainment culture and raw materials increased,the other six functions of ecosystem service value reduced;the value coefficient of the Changhe River Basin is not elastic,which is suitable for the actual situation of the Changhe River Basin,the estimation value of the ecological service value is credible.(3) The ecosystem service values brought about by the change of land use type in the Changhe River Basin between 2005 and 2015 decreased,which decreased by 6.28× 104 yuan from 2005 to 2010,and the net decrease was 1.938× 105 from 2010 to 2015.关键词
