Urban Ecological Benefit Evaluation by Diversion Dam Based on Comprehensive Ecological Assessment Index System

Abstract:

The comprehensive ecological index system for cities of Jilin Province was formed by mean square difference method to analyze the annual level of social development, ecological and environmental development, economic development and comprehensive ecological environment for 4 eco-polluted cities (Jiutai, Dehui, Dunhua, Yanji) during 2002-2012. Then the effect on improving urban ecological environment by building diversion dam was evaluated quantitatively for each city. The comprehensive ecological index values of cities had all represented a smooth upward tendency except a marked growth in 2007. The diversion dam could significantly promote the comprehensive urban ecological environment level for cities of Jiutai, Dunhua and Yanji, but not for the city of Dehui.
