| 摘 要： | 本文以黄土高原泾河流域为例，通过对位于流域上游固原市的两个村落利益相关者问卷调查，研究其对生态服务产品消费状况和受偿意愿。借助SPSS软件，分析影响农户生态系统服务消费和生态受偿意愿的因素。结果表明，农户及其饲养家畜对有限的生态系统服务的消费并没有满足其营养需求，消费量受家庭人口、粮食作物面积、退耕地面积和养殖规模影响；受偿意愿与退耕地面积、养羊数量、收入水平密切相关。退耕还林还草工程的实施通过改变农户种养格局和收入间接影响了家庭消费和生态受偿意愿。基于条件价值法的理论，对该区农户因保护水源地而损失的经济利益和放弃利用的水资源价值做出初步估算。

| Abstract: | Economic development and eco-environmental restoration are the major objectives of China's western development program.This paper selected an important watershed-Jinghe watershed of western China as the study site.Knowledge of the households' consumption of ecosystem services and Willingness to Accept(WTA) has been obtained via questionnaire survey in two villages in Guyuan city,the upper stream of the watershed.Statistical methods,with the assistance of SPSS, were used to analyze the factors influencing households' consumption of ecosystem services and WTA.The results indicate that local households own a very limited disposable income leading to an unreasonable food consumption pattern and an unhealthy ratio of nutrients intake.It is concluded that households' consumption on eco-products is relevant to the size of households,and land area of food crops and arable land area converted into forest and grassland,and livestock numbers.Households' WTA is relevant to converted land area,income level of household and number of sheep reared.The implementation of land conversion policy can indirectly influence households' consumption on natural resources and WTA by changing plantation patterns,livestock numbers and income level.Settled at the water source area of Jinghe watershed,local people give up the priority to utilize the water resource,instead,they protect the water resources for the down stream users and economic development,but they had not received corresponding compensation from relatively developed regions down streams.Based on the theory of Contingent Valuation Method(CVM),this paper evaluated the households' economic loss from water resource protection.In order to balance the benefits of regions along the watershed,recommendations on building effective compensation mechanism were brought forward. |
