Abstract: Delineating and strictly observing the ecological protection red line is a national strategic requirement. In order to ensure the precise landing of the ecological protection red line in Beijing, this paper innovatively grades and classifies the red line boundary checking content based on the results of the Beijing ecological protection red line from integrating multi-source data such as geographic national conditions monitoring data, high-resolution remote sensing image data, topographic map data, land use survey data, forestry subclass data, etc. We proposes a method for optimally checking the boundaries of nature reserves, river wetlands, and other units. The comprehensive application in the verification is studied, and the accuracy, current status, integrity, coordination and boundary consistency of the ecological protection red line in Beijing are analyzed and optimized by using the ArcGIS platform to make the red line reach to 1:10 000-scale mapping accuracy, realizing accurate red line landing map. The study provides a base map for the landing, nailed piles, and management of the Beijing ecological protection red line, and provides the data basis for the comprehensive implementation of land and space planning. The research method is also applicable to the ecological protection red line boundary checking studies in other regions of the country.
