大都市区土地利用变化及其生态系统服务价值响应--以济南市为例

Land Use Change and Its Ecosystem Service Value Response in Metropolitan Areas--Take Jinan City as an Example

本文结合济南市2016年与2020年的土地利用状况,对济南市区土地利用变化及其生态系统服务价值影响进行分析,为生态可持续发展提供依据。结果表明,5年间,土地利用结构变化明显,建设用地面积不断增加,增长率为5.6%;农田绿地减少,农田减少5.35km^(2),绿地减少8.47km^(2)。未来,济南市要合理规划建设用地,切实保护基本农田和一般耕地。

Combining the land use status of Jinan City in 2016 and 2020,this paper analyzes the impact of land use change and its ecosystem service value in Jinan urban area to provide a basis for sustainable ecological development.The results show that in 5 years,the land use structure has changed significantly,and the area of construction land has continued to increase,with a growth rate of 5.6%;farmland green space has decreased,farmland has decreased by 5.35km^(2),and green space has decreased by 8.47km^(2).In the future,Jinan City should rationally plan construction land,and effectively protect basic farmland and general farmland.
