突变理论在山地生态环境脆弱性分析评价中的应用初探

An initial discussion of application of catastrophe theory in analyzing and assessingfrangibility of mountain eco-environment

突变理论创立于二十世纪七十年代,广泛应用于“软”、“硬”科学领域.根据山地环境中出现的突变现象及山地生态环境的特点,初次将突变理论应用于山地生态环境脆弱性分析与评价中,建立了山地生态环境灾害致因突变模型.在分析山地环境的自然、社会与经济状况,并建立山地生态环境稳定性评价体系的基础上,运用突变理论中的归一公式,求取山地生态环境的稳定度,从而判断该生态环境的脆弱度,并对此方法做出了评价.

The catastrophe theory, which was created in 1970s, has been used in 'soft' and 'hard' science. According to the catastrophe phenomena in the mountain environment and the character of the mountain eco-environment, in this paper, the catastrophe theory is used in analyzing and assessing the frangibility of the mountain eco-environment. The cusp model of mountain eco-environment catastrophe is made. Based on analyzing the nature, the sociality and the economy, and establishing the system of the evaluation, through assessing the stability of the eco-environment, the frangibility is estimated, and the method is appraised. Then the application of the catastrophe theory in researching in the frangibility of the mountain eco-environment is discussed.
