摘　　要：本文以南京市为例,利用支付卡式的条件价值评估(CVM)技术,通过发放调查问卷及访谈的形式对公众改善长江水质的支付意愿进行了深入研究。结果表明:(1)南京市居民对长江水质恢复的户均年支付意愿为100.66元,76.5%的受访者的支付意愿大于零,8.4%的受访问者虽有支付意愿但限于低经济收入原因支付意愿为零,15.1%的受访者拒绝支付;(2)影响居民支付意愿的主要因素包括家庭收入、环境意识及文化程度;(3)南京市居民偏爱的支付方式依次为捐款、交税、存取基金方式及提高水价,水价上涨并不是面向公众筹集长江水质改善资金的唯一有效方式。根据调查结果,本文认为增加收入,提高水环境保护意识,引入“谁收益、谁支付”观点是提高居民支付意愿的有效途径。Evidenced in Nanging area, with the contingent valuation method which structured by payment card, this paper measures public＇s willingness to pay（WTP） for water quality improvement of Yangtze River, the results show as following： （1） The mean WTP is 100.66 Yuan per family per year, 76,5 percent of respondents＇ WTP is over 0 yuan, 8.4% percent f respondents is willing to pay but their WTP equals 0 because of low family income, and 15.1% percent of respondents is unwilling to pay for water quality improvement; （2） The respondents＇ WTP is relate to his Family income, environmental ecological consciousness of water quality improvement and education degreed; （3） Donation, tax, fund and higher water price are the possible payment choices.
