| The danger of environmental retrogression is kept on guard highly in China. The study of ecological security is becoming the major foreland and task in ecology and resource and environment science.The paper has discussed the concept of ecological security and has an analysis of the appraisal of ecological security in domestic and abroad firstly. Then it analyses the feature of natural reserve ecological security . This paper does an analysis of the relations between natural reserve ecological security and the sustainable development, and bases on the ecosystem of natural reserve and their neighboring communities and accordance with the basic requirement of standard ecological security evaluation, source and optional principle of standard value, so uses the 24 evaluation indexes of natural reserve ecological security. Based on the "Pressure-State-Response" frame model, through pressure and quality , protect and renovate of resource-environment to build the ecological security evaluative indexes system of Minjiang Yuan Natural Reserve and its adjacent areas. And calculates the result of the proportion of every index with AHP method, and this article has adopted "safe index method" to standardize the indices' values, synthesized the single index, and evaluated the general security value. Use the evaluation result to evaluate the ecological security. The result of the research demonstrates that the Minjiang Yuan Natural Reserve and its adjacent areas' insecurity index number is 0.2701, which is placed in a kind of slightly insecurity" condition. But its general condition is good. Finally, according to the ecosystem conditions, the paper puts forward some countermeasures and discusses the warning mechanism of ecological security on natural reserve. Lastly, the sustainable development of natural reserve and their adjacent communities will come true. At the last part, the article makes some discussions about the breakthrough and the progress, and puts some suggestions for the further study. |
