黄土高原生态系统服务价值演变及驱动力分析
Analysis of the Evolution and Driving Forces of Ecosystem Service Value in the Loess Plateau
摘要
Abstract
The Grain for Green Project has led to remarkable changes in land use and ecological environment on the Loess Plateau.Based on the land use data,vegetation factors and social and economic data of 2000,2010 and 2020,revising the improved table of equivalent factors of ecosystem service value,using spatial autocorrelation analysis and geographical detector,the ecosystem service value of different grid units was calculated as well as the spatial and temporal variation characteristics of ecosystem service value and the driving mechanism of spatial dif-ferentiation were discussed.The results show that comparing with 2000,the area of forest land and construction land is increased,the area of grassland is decreased slightly,and the area of cultivated land is decreased significantly in 2020.The ecosystem service value in 2000,2010 and 2020 is 756.554,1 147.326 and 1 433.551 billion yuan respectively.The ecosystem service value of grassland and forest land accounts for a relatively large proportion.Among the types of ecosystem service value,the regulation service value is the highest,followed by the sup-port service.The spatial aggregation characteristics of ecosystem service value are mainly high-high aggregation and low-low aggregation.Nor-malized vegetation index(NDVI),precipitation,net primary productivity(NPP),ecological land area proportion and land use degree have significant effects on the spatial differentiation of ecosystem service value.关键词
