摘要
基于ArcGIS对属性CHANGETYPE进行赋值,提取环翠区地表覆盖变化信息,并对结果进行统计分析。结果表明技术方法简便有效,能够较好地反映当年地类实际变化情况,为年度地理省情监测及统计分析常态化、规范化提供经验。
In this paper, we studied the monitoring method of surface coverage in Huancui Area in 2017. We expanded tag, assigned the property of CHANGETYE based on ArcGIS, extracted surface coverage change information of Huancui Area, and analyzed the statistical results. The result shows that the technical method studied in this paper is simple and effective, which can better reflect the actual changes of land types in the current year, and provide experience for the normalization and standardization of annual geographical conditions monitoring and statistical analysis.
