In this paper, the principles and standards of eco-environmental warning assessment were discussed, and the warning types of eco-environment were also stated, meanwhile, the indexes and models of eco-environmental warning appraisal were established. Finally the eco-environmental warning assessment results of 39 countries (or cities, district, special district) in Wujiang River watersheds were showed in this paper. By means of the Delphi, build judgment matrix.，work out the largest eigenvalves and eigenvectors by product method, determinate the weight and calculate out the quality scores of each evaluation index and ecological environment system. The results showed: the change speed and change trend among different counties at different stages showed relatively large difference. The eco-environmental quality of Anshun, Pingba, Longli, Guiding and Shibing county was much better and more stable than other counties. It will be based for the development and harness of Wujiang valley.
