| 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, environment, land resources and manpower interference and so on.The results show that the ecological environment vulnerability is in Ⅲ level in Minqin oasis, which is very fragile.Simple and easy to calculate, the method provides a new way of thinking for the vulnerability assessment of the ecological environment in arid regions of Northwest China. |
