| Ecological Qilian Shan national reserve and its geographical location determines its important position in the national layout of ecological construction in. Present situation and influence factors of Qilian Shan protection zone of ecological security, contribute to the country and reserve managers find state level ecological protection zone of the place, and find the effect on the ecological security of the more important factors, so that the country and protected areas in order to solve the problems of limited resources, promote ecological security level protection.This study reviews the ecological security and ecological security evaluation of the research literature, discusses the basic theory of ecological security assessment, analysis of the ecological predicament facing Qilian Shan reserve, which created Qilian Shan reserve behavior safety evaluation index system, calculate the value of each index, and advice from experts point of view, using the analytic hierarchy process to calculate the weight of each index in the index system of values, the relevant international standards, national standards and related research on the various indicators and set up a safe or unsafe value standard value for reference on the basis of this, using data dimensionless method to calculate the various indicators of unsafe value, finally according. to the composite index method to calculate the comprehensive index of ecological security of Qilian Shan.Through calculating the ecological security index Qilian Shan reserve is0.5146, on the basis of relevant research results of the ecological security state is divided into five grades (slightly less safe, unsafe, not very safe, very unsafe and extremely unsafe), on the basis of the standard can be known at present Qilian Shan reserve of ecological status in third grade and the ecological status "unsafe" state. On the basis of the results of the study at last put forward the ecological security level promotion strategy. |
