基于生态系统服务价值最大化的皖江城市带土地利用结构优化

Maximizing the Value of Ecosystem Services Based on the Wanjiang River Urban Belt Land Use Structure Optimization Analysis

为了掌握皖江城市带生态系统服务价值最大化的土地结构优化方案,利用Arcgis土地利用、GM(1,1)模型、Lingo软件对皖江城市带2000—2020年土地利用结构进行分析研究.结果表明:(1)2000—2020年皖江城市带土地利用类型以耕地和林地为主,占比约85.00%.(2)研究区生态系统服务价值呈现先上升后下降趋势,20年间约增长了22.18亿元,变化率为10.30%.(3)基于土地利用结构优化方案,皖江城市带生态系统服务价值提高了3.20%.通过优化皖江城市带生态系统服务价值,可为研究区的生态发展规划提供一定的数据支持.

In order to grasp the land structure optimization scheme for maximizing the value of ecosystem services in the Wanjiang River urban belt, Arcgis land use, GM(1,1) model and Lingo software were used to analyze and study the land use structure of the Wanjiang River urban belt from 2000 to 2020. The results showed that:(1) The land use types in the urban zone of Wanjiang River from 2000 to 2020 were mainly arable land and forest land, accounting for about 85% of the total.(2) The value of ecosystem services in the study area showed a trend of increasing and then decreasing, with an increase of about 22.18 billion in 20 years and a change rate of 10.3%.(3) Based on the land use structure optimization scheme, the value of ecosystem services in the urban belt of Wanjiang River increased by 3.20%. By optimizing the value of ecosystem services in the Wanjiang Economic Zone, some data support was delivered for the ecological development planning of the study area.
