Research On The Ecological Security Assessment Of Karst Degraded Landscape Based On 3S Technology

The ecological security is the newest explanation of the relationship between the human-race and the nature in all ages. The research of ecological security is the hottest topic of geographic science, environmental science, and ecological science. And the ecological security assessment is the core and foundation of the research of ecological security. As for the kast fragile eco-environmental system, there has been no either theory or case study of it in the filed of ecological security up to now. With the help of the key laboratory of environmental information system and the protection of eco-environmental system in Guizhou province, and the support of the project of the quality improving of CBERS satellite remote sensing images and their typical application in the filed of eco-environmental science, this paper chose Guiyang city as a case, and started in to research on the ecological security assessment of kast degraded landscape based on "3S" technology.Through a large number of reading, exploring, and practice, this paper has finished:â‘ research on the relationship between ecological security and other relative concepts such as ecosystem services, ecological risk, ecosystem health, ecological carrying capacity, and sustainable development, et al.â‘¡research on the elements of ecological security assessment system, the ways and means of ecological security assessment, and the working procedure of ecological security assessment, et al.â‘¢research on the classification of kast degraded landscape, the evaluation index of ecological security assessment of kast degraded landscape, and the technological framework of ecological security assessment of kast degraded landscape based on...
