Abstract: Based on the data processing methods and experiences of natural forest protection and restoration in Yunnan province, this paper systematically summarizes the key points of the data processing process for natural forest protection and restoration, starting from verifying the boundaries of case-filing units, preprocessing natural forest parcel data, implementing management and protection tasks, database inspection, and data summary and submission. It analyzes the major existing problems and proposes solutions. Through multiple trials in practical work addressing these issues, methods for solving problems are summarized and inducted. Some key technologies for data processing are explored using ArcGIS spatial analysis tools. Some repetitive data processing and inspection methods are solidified into ArcGIS models, which automatically inspect data and export inspection results, serving as a reference for subsequent natural forest protection and restoration data processing work.
