土地卫片执法数据能够真实反映给定区域的土地利用变化情况，可以为区域土地资源优化配置和土地管理提供基础依据。近些年来，随着我国卫片执法政策的陆续出台和落实，使得针对某一地区的长时间序列数据集更可获得。文章基于惠州市惠阳区2017—2021年的土地卫片执法数据，分析了该区域的土地利用变化。研究表明：惠阳区2017—2021年间土地利用面积大幅增加，尤其是交通运输用地、工矿仓储用地面积占比不断升高，每年仍有一定数量耕地被占用，淡水街道、秋长街道、新圩镇和镇隆镇等临深镇街的交通运输用地和工矿仓储用地具有明显区位意义，土地利用空间分布临深聚集效应显著。论文建议当地政府应加强土地利用类型优化布局、均衡发展和耕地保护工作。

the data of law enforcement of land satellite images can reflect the change of land use in a given region, and provide a basis for the optimal allocation of land resources and land management. In recent years, with the coming out and implementation of our country's satellite law enforcement policy, it makes the long-time sequence data set more available for a certain area. Based on the 2017-2021 data from Huiyang District, Huizhou, the paper analyzed land use change in the region. The study shows that in Huiyang District, land use in the 2021 has increased significantly from 2017 to 2017, with the proportion of land used for transportation, industrial and mining storage increasing. A certain amount of arable land is still occupied every year, the transportation land and industrial and mining storage land near Shenzhen Street, such as Danshui Street, Qiuchang Street, Xinwei, Meizhou Street and Zhenlong town, have obvious regional significance, and the spatial distribution of land use has obvious effect of gathering near depth. The paper suggests that the local government should strengthen the land use type optimization layout, the balanced development and the cultivated land protection work.
