摘要

This paper takes the Tongyu County as an example,based on the evaluation indicator system of eco-environmental stress,using the method of the entropy-GM(1,1),the eco-environmental stress is evaluated and forecasted.Results show that the shortage of water resources,the desertification,the salinization,the grassland degeneration and the population increase are major stress factors of eco-environment worsening in the Tongyu County;eco-environmental stress coefficient from 1994 to 2013 in the region was increasing year by year,and the stress degree jumped from level-III to level-IV.The forecast results show that if the measures don't be taken to protect eco-environment,the stress coefficient still grows,and the stress degree aggravates.In view of the above situation,we take the measures to lighten eco-environment stress,and promote the coordinated development of resources,environment and social economy,which is linking rivers and lakes,water resources optimization,preventing and controlling the desertification and the salinization,improving the degenerated grassland.
