基于高分遥感的董家口经济区土地利用变化分析

Land Use Change in Dongjiakou Economic Zone based on High-resolution Remote Sensing

基于2014年和2018年的高分遥感影像数据,提取了青岛市董家口经济区的土地利用类型信息,并运用土地利用转移矩阵对2014—2018年董家口经济区土地利用变化进行定量分析。结果表明:2014—2018年董家口经济区土地利用类型的数量变化以建设用地的增加及耕地和水域湿地的减少为主;在空间分布上,建设用地的增加主要集中在董家口港口区和整个经济区的道路建设上,这与董家口经济区的发展规划相吻合。总体来说,董家口经济区规划理念立足于可持续发展,生态环境保持良好。

Based on remote sensing data in 2014 and 2018,the land use types of Dongjiakou Economic Zone,Qingdao City,was extracted,and the quantitative analysis was made by using the transition matrix of land use for nearly four years.The results showed that:the change of land use types from 2014 to 2018 was dominated by an increase in construction land and a decrease in cultivated land and water wetlands.In terms of spatial distribution,the increase in construction land was mainly concentrated on Dongjiakou Port Area and the road construction in the entire economic zone,which is in line with the development plan of the Dongjiakou Economic Zone.In general,Dongjiakou Economic Zone planning concept is based on sustainability and the ecological environment remains good.
