摘要
以黄平县为研究区域,基于多轮土地调查矢量成果数据,运用对比统计分析与空间叠加分析的方法,获取2018年和2020年两个时期土地利用分布情况,以及2018年至2020年黄平县土地利用变化情况。结果表明,2018年到2020年黄平县土地利用发生一系列变化:耕地面积明显减少,林地增加幅度大,林地与耕地间流转较为明显;草地锐减,主要流向林地。通过矢量数据对比统计分析,为县域土地利用变化监测提供有效参考和依据。
Taking Huangping county as the research area,based on vector data from multiple rounds of land survey,comparative statis-tical analysis and spatial overlay analysis were used to obtain the land use distribution in 2018 and 2020,as well as the land use chan-ges in Huangping county from 2018 to 2020.The results show that from 2018 to 2020,there were a series of changes in land use in Huangping county,with a significant decrease in cultivated land area and a significant increase in forest land.The circulation between forest land and cultivated land was more obvious;Grassland has sharply decreased,mainly flowing into forest land.Through the com-parative statistical analysis of vector data,it provides an effective reference and basis for the monitoring of land use change in the county.
