洱海流域上游农户环保支付意愿及影响因素研究

Willingness to Pay and Its Influencing Factors of the Farmers in Upper Reaches of Erhai Basin for Ecological Environmental Protection

洱海是云南滇西母亲湖,是周围百姓赖以生存的生命之源。洱海流域源头农村居民的生产、生活行为对洱海生态环境的保护起到至关重要的作用。基于实地调研数据,运用条件价值法探讨了洱海流域源头3个镇农户对洱海环境保护的支付意愿,并通过EViews软件建立回归模型分析了影响当地农户环境保护支付意愿的主要因素。结果表明,洱海流域源头农户对环境保护的支付意愿介于106.69~131.72元/（年·户）,而是否愿意为改善环境减少农药化肥使用和对于当地环境污染状况及危害的认知程度是影响其环境保护支付意愿的主要因素,为科学制定合理、有效、可操作的洱海流域环境保护经济政策提供了决策支持。

Erhai is the mother lake of Dianxi in Yunnan province and the source of life for local people. Production and life behavior of farmers in upper reaches of Erhai Basin play a crucial role in protecting the environment of Erhai. Based on the field survey data, using Contingent Valuation Method （CVM）, the authors discussed farmers＇ willingness to pay for the environment protection of Erhai, living in the three towns in Erhai Basin headstreams, and established a regression model by EViews sofLware to analyze the main factors influencing local farmers＇ willingness to pay for protecting environment. The results showed that the local farmers were willing to pay 106.69 - 131.72 yuan per household every year to protect the environment in Erhai Basin headstreams, the main factors influencing the willingness to pay for environment protection were improving environment with decreasing chemical fertilizer and pesticide use and the awareness of local environment pollution and its damage, which provided support for making reasonable, effective and exercisable economic policies on the environment protection of Erhai Basin.
