摘要

生态环境脆弱性评价对认识、保护和改造生态环境

促进人与自然的和谐具有重要意义。分析了江西省生态环境脆弱性的表现特征

结合生态环境潜在脆弱性、胁迫脆弱性、现实脆弱性

提出了生态环境脆弱性动态评价的方法和步骤

并对江西省生态环境脆弱性进行了动态评价。研究表明

江西省生态环境脆弱性总体趋于缓和

2000年与1985年相比

变化主要集中在由较高脆弱性向较轻脆弱性转变

总面积为102820.49km

占全省总面积的61.61%。同时

根据生态环境脆弱性现状和发展趋势

讨论了生态脆弱性分区问题

并提出了相应的生态环境治理对策。

Abstract

Dynamic evaluation of ecological frangibility is not only important to understand

preserve

and improve ecological environment

but also essential to promote the harmony between man and nature. The characteristics of ecological environment frangibility in Jiangxi Province are analyzed. It is necessary to combine potential frangibility

intimidate frangibility

and realism frangibility together for the dynamic evaluation of ecological frangibility. The method and step of dynamic evaluation of ecological frangibility in Jiangxi Province are then presented. The analysis indicates that the eco-environmental frangibility in the province tends to relaxation. By comparing 1985 with 2000

the dynamic change of ecological frangibility is from high frangibility to low f rangibility and the total area is 102820.49 km2

which accounts to about 61.61% of the total area of Jiangxi Province. At the same time

the evolution process and developing trend of ecological frangibility are analyzed and the division of ecological frangibility and the management of the fragile ecological environment are discussed.
