基于遥感数据的雄安新区土地利用变化

摘要
基于Landsat TM/OLI影像数据,采用最大似然法对1996—2016年雄安新区的土地利用信息进行提取.从土地利用类型、土地利用变化空间形式、土地利用程度、土地利用变化方向4个方面,分析了雄安新区土地利用变化特征和驱动力.采用基于时间段的土地利用动态度的计算方法并提出时空演变指数,具有一定的科学性.结果表明:近20 a间,雄安新区最主要的土地利用类型是耕地;土地利用发生了显著的变化,主要表现为耕地面积持续减少和居民地面积持续增多;土地利用程度逐年增加,土地利用处于发展期;居民地增加的面积主要是从耕地转化而来;人口增加、经济增长是土地利用变化的主要原因.
Based on Landsat TM/OLI image data, this paper uses maximum likelihood method to extract land use information of Xiong′an New Area from 1996 to 2016. This paper analyzes the characteristics and driving forces of land use change in Xiong′an New Area from four aspects: the type of land use, the spatial form of land use change, the degree of land use and the direction of land use change. The paper adopts the calculation method of dynamic degree of land use based on time period and proposes the index of spatial and temporal evolution, which is scientific. The results show that over the past 20 years or so, the main type of land use in the Xiong′an New Area has been cultivated land; significant changes have taken place in land use, which is mainly manifested in the continuous reduction of the area of cultivated land and the continuous increase of the area of residential land; the degree of land use increases year by year, and land use is in the development period; the increasing area of the residential land is mainly converted from cultivated land; the increase in population and economic growth are the main reasons for the change of land use.
