| Abstract: | According to the current situation of ecological environment of the oasis of Jiuquan, the oasis early warning appraisal index system of ecological environment of Jiuquan have been set up. The analytic approach of the level is used to carry on statistical analysis of every factor in this index system. The concrete weight of every ecological factor have been defined, the importance sequencing of every influence factor has been drawn. According to the result of arranging in an order, the early warning appraisal to the ecological environment of the oasis of Jiuquan was done, and the prevention and cure measure of the main ecological problem has been proposed. |
