基于GEE平台的县域生态服务价值时空演变研究
Spatio-temporal Evolution of Ecological Service Value at County Level Based on GEE Platform
摘要
Abstract
Base on GEE platform,we obtained the land-use data every five years from 2005 to 2020,and used the value equivalent factor method combined with vegetation index to calculate the ecosystem service value(ESV),revealing the spatio-temporal variation characteristics of ESV in Conghua District in the past 15 years.The main results are as follows:①during the study period,forest showed a trend of fluctuation and in-crease,cultivated land gradually shrank,and construction land gradually expanded,increasing by about 100%.②From 2005 to 2020,ESV in-creased first and then decreased in Conghua District,with a net increase of 304 million yuan.③ESV generally presented obvious spatial differen-tiation characteristics of high in the north and low in the south.关键词
