| Abstract: | Bengbu,a city in the middle reaches the Huaihe River Basin,was selected as a case city.A quantitative analysis was conducted into the urban ecological security and temporal evolution(from 1985 to 2003) by means of Factor Analysis(FA).The result showed that the features of the temporal change of the city's water ecological security were apparent,with a trend of changing for the better.Such factors as the urban social economical development,the control of the pollution sources in both industry and agriculture,and the water pollution management and control have exerted a positive influence on the temporal change of the urban water ecological security.At the end,some useful countermeasures were provided to maintain and improve the urban water ecological security. |
