【 摘 要 】

The water quality plays an important role for residents living in Xiangjiang valley, Hunan province, southern China. In this study, the contingent valuation method (CVM) was used to estimate the value for improving water quality of Xiangjiang for residents who live in in Chang-Zhu-Tan city cluster including Changsha, Zhuzhou and Xiangtan of Xiangjiang valley.

According to ranges of willingness to pay (WTP) for residents from CNY 2.0 to 50.0 Yuan (from US$ 0.3 to 7.46), the average WTP was calculated CNY 17.18 Yuan (US$ 2.56) per month per household, and the total economic value was CNY 0.848 billion Yuan (US$ 0.127 billion) for Chang-Zhu-Tan city cluster. Residents were willing to contribute a portion of their incomes to improve the quality of drinking water. Among all factors, there were significant relationships between income and sex and WTP (p
