Abstract: According to the time series data from 1997 to 2008 and the basic principles and steps of the theory of AHP,the index system of integrated assessment of the eco-environment quality of Kashghar City is established,the weights of every ecological factor are defined,the importance of every factor of influence is sequenced,the comprehensive index of eco-environmental quality is calculated,and finally the eco-environmental quality of the city is evaluated.The results show that the index fluctuates.There is difference between the year before 2002 and after 2002, before 2002,the index is low and had been gradually decreased;after 2002 the index shows fluctuation,but is still higher than 2002,which shows that the environmental quality has been improved,but the overall trend is not so good.The evaluation shows that the environmental quality of Kashghar City is poor and the situation is not optimistic,therefore Kashghar City must take measures to strengthen the construction work on its ecological environment.
