摘要
选取秦皇岛市2000年、2010年和2020年三期Landsat影像为数据源,运用土地利用转移矩阵和动态度等研究方法,统计分析秦皇岛市2000—2020年土地利用类型变化情况。结果表明:2000—2020年,建设用地变化最为明显,2020年建设用地面积为945.20 km^(2),与2000年相比,增加486.16 km^(2),主要是耕地和草地的转入;在动态度方面,建设用地变化幅度最大,面积增速最快;总体而言,秦皇岛市土地利用变化幅度呈递增趋势。
The Landsat images of Qinhuangdao City in 2000,2010 and 2020 were selected as the data source,and the changes in land use types in Qinhuangdao City from 2000 to 2020 were statistically analyzed by using research methods such as land use transfer matrix and dynamics.The results show that from 2000 to 2020,the change of construction land is the most obvious,and the construction land area in 2020 is 945.20 km^(2),an increase of 486.16 km^(2),mainly the transfer of cultivated land and grassland.In terms of dynamics,the construction land has the largest change and the fastest growth rate of the area.Overall,the land use change in Qinhuangdao shows an increasing trend.
