为研究G市近十年的土地利用情况,选取2013和2022年的地表覆盖数据作为数据源,借助ArcGIS 10.8软件进行镶嵌、裁剪和融合等处理,通过分析土地利用的变化幅度、动态度以及转移情况,了解其土地利用/覆被变化情况.结果显示,与2013年相比,2022年研究区的耕地、裸地、灌木地和人造地表面积均有所增加,而林地、草地和水体面积呈减少趋势.耕地、灌木地、裸地和人造地表的土地利用动态度指数分别为0.95%、1.46%、6.80%和1.63%,其中裸地的变幅最为明显;林地、草地和水体的土地利用动态度指数分别为-0.73%、-7.28%和-3.10%.总体而言,土地利用转移变化主要体现在林地、人造地表和水体方面,其中部分林地和水体主要向耕地等转变.本研究为土地可持续利用发展提供参考.
Research on urban land use/land cover change in G City from 2013 to 2022
To investigate the land use of G City in recent ten years,the land cover data of 2013 and 2022 were selected as the data source.With the help of ArcGIS 10.8 software,processes such as mosaic,clipping,and fusion were performed.By analyzing the change amplitude,dynamics,and transfer of land use,the land use/cover change situation was understood.The results showed that compared to 2013,the area of cultivated land,ubare land,shrub land and artificial surfaces in the research area increased in 2022,while the area of forest land,grassland and water bodies gradually decreased.The land use dynamic attitude of cultivated land,shrub land,ubare land and artificial surfaces was 0.95%,1.46%,6.80%and 1.63%,respectively,and the ubare land had the most obvious variation.The land use dynamic attitude of forest land,grassland land and water bodies was-0.73%,-7.28%and-3.10%,respectively.In general,land use transfer changes in the study area were mainly reflected in forest land,artificial surfaces and water bodies,in which part of forest land and water bodies were mainly transformed into cultivated land.This study provided a reference for sustainable land use development.
