Abstract: In the natural resources inspection work, in order to determine whether there is an illegal land use in the target area, ArcGIS software needs to be used to perform spatial calculations and summary statistics on the target area and land pattern data to provide data support for the implementation of the inspection work. At present, manual integration has problems such as the high production cost, the large workload, low accuracy, and inconsistent data naming and storage formats. For those reasons, this article realizes the automatic matching method of the ground pattern based on Python. This method can automatically complete the spatial calculation of the target area and the ground pattern, field calculation, Excel export and generation of pivot tables, etc. It greatly reduces the workload of the technical staff, effectively shortens the data preparation time of the inspection work, and has practical significance for improving the efficiency of the natural resource inspection work.
