摘要
白城市是吉林省西部典型生态脆弱区,土地利用变化对区域生态环境产生重要影响。利用1985与2000年的Landsat TM和2015年Landsat OLI遥感影像为数据源,分析土地利用变化特征;采用Costanza估算生态服务价值法,基于谢高地的生态服务价值当量因子表,定量白城市土地利用变化生态服务价值系数表,测算白城市土地生态服务功能价值。提出因地制宜优化农业结构、提高城市土地利用率、控制城市规模、保护生态用地优化生态环境等决策,旨在促进该市经济社会持续发展。
Baicheng City is an ecologically fragile area in the agro-pastoral ecotone.Changes in land use there have an important impact on the regional ecological environment.Using Costanza to estimate the ecological service value method,the Baicheng urban land ecosystem service value is measured in this typical ecologically fragile area of western Jilin.To promote the sustainable economic and social development of the city,this study uses Landsat TM in 1985,Landsat TM in 2000,and Landsat OLI in 2015 as data sources to analyze the characteristics of land use change,with Costanza used to estimate the ecological service value method,based on XIE Gao-Di's ecological service value equivalent factor table,quantitative white.The value index of urban land use change ecological services is used to calculate the functional value of land ecological services in Baicheng City.As a result,the author proposes decision making to optimize the agricultural structure,improve the urban land use rate,control the city scale,and protect the ecological land to optimize the ecological environment.
