Valuation of Urban Water Eco-System Service Functions

Abstract

Water eco-system service functions refer to the natural environment conditions and utilities formed by the water eco-system and ecological process to maintain human survival. They are the eco-environmental conditions for human survival and development and the basic resources of human social and economic development. During the rapid development of the urbanization process, the urban water eco-system has been increasingly influenced by human activities. Humans have severely destroyed the original urban water system while exploiting and utilizing water resources on a large scale, and consequently resulted in a series of water environment problems. In order to build a harmonious urban eco-system and reasonably utilize and protect water resources, it is of great importance to analyse and improve the urban water eco-system service functions and conduct the valuation, so as to arouse the public’s awareness of recognizing and protecting the urban water resources.
