Abstract: This study uses Beijing’s 2015,2017,and 2019 three phases of the geographic national survey and monitoring data to analyze the spatial change characteristics of the land surface cover within the red line of Beijing’s ecological protection,and on the basis of the global and local Moran’s I spatial autocorrelation analysis,spatially identify areas with significant ecological restoration and significant ecological damage within the red line of ecological protection.Studies results have shown that the ecological land within the ecological protection red line from 2015 to 2019 is in an outflow state as a whole,and various change patches have obvious spatial autocorrelation effects.15 areas are densely human activities,including Wuling Mountain and surrounding mountains,Songshan and Yudu Mountain Reserve,Nanhaizi Park,Miyun Reservoir,HuaishaHuaijiu River,and Pinggu Section (southwest section) of the Yanghe River are areas with significant ecological damage.It is recommended that the above areas be increased supervision;areas with significant ecological restoration are in the Miyun section of the Jingmi Water Diversion Canal,the other 8 areas all coexist with manmade destruction and repair activities.The research provides a decision-making basis for strictly observing the red line of ecological protection,accelerating the construction of beautiful Beijing and the construction of ecological civilization.The research method is also applicable to the monitoring of changes in surface cover within the red line of ecological protection in other regions of the country.
