Abstract:: The article established the ecological security assessment index system of water environment in Zaozhuang City, which was based on the "state-pressure-response" index system and the situation of water environment in Zaozhuang city.The assessment adopted the standardization for all the index data and used variant coefficient method to get the weight of every index.The final result was divided into five grades, which corresponded to serious alarm, secondary alarm, early alarm, almost safety and safety.The article made temporal analysis to indicate the development trend of the ecological security of water environment in Zaozhuang city by the data from 1999 to 2005.The results show: (1) At present, there are three main problems in water environment in Zaozhuang city, such as the badly polluted rivers, deficient local water resource, great pressure from economy development. (2) From 1999 to 2005, the assessment value declined year after year and the assessment value of state index kept falling.These indicated that the eco-system of water environment in Zaozhuang city was in early alarm grade and being damaged continuously. (3) The drop was mainly brought out by the pressure of water environment, which was especially caused by the country non-point source pollution in Zaozhuang city.
