摘要
国土调查是自然资源部门掌握所辖范围内地类变化情况的重要手段。随着科技的进步,国家对土地管理的要求更加严格,掌握基础地类变化不仅是掌握一个数字的变化,还包括地类变化地块的空间位置,从而实现地块变化数量和位置的统一管理。介绍了利用ArcGIS软件计算第三次全国国土调查地类与第二次全国国土调查地类对比分析后流量的方法,更好地掌握了变化地类的前世与今生,使得自然资源部门对土地的管理更加方便和快捷。
National land survey is an important means for natural resource departments to grasp the land type changes.With the development of national science and technology,the land management requirements are stricter.Mastering the real change of basic land type is not only to master the change of a number,but also to master the spatial position of land type change plots,which can realize the unified management of the number and location of land change.In this paper,we introduced how to use ArcGIS software to calculate the changes of land type after comparative analysis between the third national land survey and the second national land survey,which could better grasp the past and present of change land types,and be convenient for the natural resource department to manage the land efficiently.
