Has become a hot spot of land use / cover change and ecological security research and cutting-edge research areas. Two typical area of ??the Changbai Mountain area, study area, study area land use / cover change and ecological security situation analysis. Study area using the 1977 MSS data, 1993, 1996, 2007 TM, ETM data 1999 five of remote sensing data, the study area using 1976 MSS data, TM data in 1992, 2007, 2001, ETM on remote sensing data, as well as the corresponding region of the terrain data, the application expert knowledge system classification method of remote sensing image classification, the study area, the land use / cover change data, and, respectively, for the entire study area land use / cover Change situation, the pace of change and the main analysis methods of land use transition matrix, land use dynamics, such as the degree of land-use model, and the application of land use relative change along the model of the study area borders a 20 km buffer of the study area analysis of the relative change in position along the 10 km buffer Borders, drawn in the study area land use / cover change in the general trend, differences in status of border land use / cover change. The application of ecological risk index model to evaluate the security situation on the overall ecology of the study area, variance analysis and ecological security of the border situation. Changbai Mountain area of ??cross-border land use / cover change and ecological security research can provide the necessary basis for the ecological protection cooperation between the two countries in the future, and to provide support to the global ecological and environmental protection. Through research and analysis, we draw the following conclusions: 1. Overall, the two study regional land use / cover change presents woodland gradually reduce farmland and other land presents a significant increasing trend, which is the main human activities due to interference. The Korean side of change intensity greater than the side of the degree of change in China. Overall ecological security conditions of the study area in each time period is safe to safer state ecological risk index showed a gradually increasing trend; ecological security situation in the time period of the study area in the study area, two the Chinese side of the ecological security situation in North Korea on one side. Analysis through land use / cover change in the driving force, the natural and social factors affecting regional land use / cover change factors, social factors play a leading role. Development and utilization of resources at the same time continue to take appropriate measures to protect the ecological environment, the North Korean side of the economic backwardness lead to uncontrolled development and utilization of resources, and a negative impact on the ecological security of the entire region.
