摘要
土地是自然界不可或缺的资源,土地利用反映了人地关系。随着人口数量的持续增加和社会工业化、城市化的持续推进,如何科学地开发利用宝贵的土地资源越来越受到人们的重视。本文通过2013年和2023年的Landsat影像数据,结合遥感与GIS,对10年间合肥市土地资源进行监测与分析,结果表明,经过10年的城市发展,合肥市耕地面积减少了65707.92 hm 2,建设用地增长了39181.05 hm 2,林地减少了1728.27 hm 2,水域增加了28255.14 hm 2。
Land is an indispensable resource in nature,and land use reflects the relationship between humans and land.Accompanying with continuous increase in population and continuous promotion of social industrialization and urbanization,how to scientifically develop and utilize valuable land resources has been increasingly valued by people.In this paper,by using Landsat image data from two periods in 2013 and 2023,and combining with remote sensing and GIS,land resources in Hefei city over the past decade have been monitored and analyzed.As showed by the comparison results,after ten years of urban development,the cultivated land area in Hefei city has decreased by 65707.92 hectares,construction land has increased by 39181.05 hectares,forest land has decreased by 1728.27 hectares,and water bodies have increased by 28255.14hm 2.
