Paper Abstract

In this article, the analytic hierarchy process was used to make evaluation on ecological security in Xinjiang, China , we have calculated the degree of environmental subsystem, social subsystem, economic subsystem and total system of ecological security system in Xinjiang from 1988 to 2010. We have analyzed warning and controlling ecological security of Xinjiang in short-medium range(2004-2010). By using sensitivity factors that influence ecological security system of Xinjiang, which includes environmental subsystem, social subsystem, economic subsystem and total system. The main conclusions as follows: From 2004 to 2010,the ecological security situations of environmental subsystem are rising and economic subsystems are obviously ascendant in Xinjiang; According to the contributions of these three subsystem, the list is successively: Environmental subsystem >Social subsystem >Economic subsystem; proved that the ecological environment structure of Xinjiang is very fragile and unstable from holistic standard of ecological security and quantity.
