| 摘 要： | 针对民勤绿洲水资源、环境和土地利用现状,利用定量分析方法对民勤绿洲生态环境脆弱性进行总体评价.在分析影响民勤绿洲生态环境因素的基础上,将模糊理论、层次分析法和物元可拓集合有机结合起来,建立了民勤绿洲生态环境脆弱性评价的模糊物元模型.该模型充分考虑水资源、环境、土地资源和人工干预等指标.计算结果表明:民勤绿洲生态环境脆弱性状况总体评价为Ⅲ级,即非常脆弱.该方法简捷、易于计算编程,为西北旱区生态环境脆弱性评价提供了一种新的思路.

| Abstract: | According to the use of the status quo of water resources,environment and land use,the vulnerability of ecological environment in Minqin oasis is assessed with quantitative analysis.Based on the analysis of impact factors of the ecological environmental of Minqin,a fuzzy matter-element model is established for the Minqin oasis eco-environmental vulnerability evaluation on the basis of the theory of fuzzy,AHP and matter-element,in which some indices are taken into consideration,such as water resources,enviro... |
