中文摘要	以渭河陕西段河道为研究对象，依据陕西省统计年鉴和水资源公报等数据，应用生态学与经济学方法，参考2001年联合国开展研究的千年生态系统评估体系，对渭河陕西段河道生态系统的4类服务功能（供给功能、调节功能、文化功能和支持功能）及内含的11个亚类的服务功能价值（供水、提供水产品、水力发电、调节水分、输沙、净化水质、调节气候、净化空气、提供美学景观、休闲旅游、维持生物多样性）进行综合化、定量化评估。结果表明：渭河陕西段河道2012年生态服务总价值为3 563.61 10~8元，是陕西省同年GDP的0.25倍。其中供给功能的服务价值为2 735.62 10~8元,所占百分比最大，为76.76%，其次为调节功能服务价值、文化功能服务价值、最后为支持功能服务价值，所以渭河陕西段河道生态系统在供给功能和调节功能方面发挥着极其重要的作用，处于核心功能地位。
英文摘要	With the implementation of China’ s Western Development Program,the excessive growth of population has become a bottleneck ahead for ecologically fragile areas. Meanwhile, with over-exploitation and utilization of water resources,the ecological and environmental problems have become more serious in river basin for the western regions. In particular, the environmental fragile zone is a sensitive monitor of water resource in arid and semi-arid regions. On the consideration of sustainable development strategies,a pattern for coordinated development of society, economy and environment is urgent to be proposed. It is,therefore,determination of stream’ s ecosystem service value is of great importance in well understanding the status of river health and is great helpful for rational utilization of stream,ecosystem functions for social-economic development. As a case study,this paper focuses on the estimation of instream,ecosystem service value for the Weihe River in Shaanxi Province. According to related scientific theories and methodologies especially from the disciplines of ecology and economy as well as field investigation, the methods for estimation the stream’ s ecosystem service value are proposed,which includes C D production function method,market valuation method,shadow engineering method,opportunity cost method,recovery cost method, market price replacement cost method and so on. On the basis of calculation from these methods,the stream ’ s ecosystem service value for the Weihe River is determined. The results show that stream,ecosystem service value for the Weihe River of Shaanxi Province in a typical year of 2012 is 356.36 billion Yuan RMB, which accounts for 25% of total output value of the Shaanxi Province in the same year of 2012. Among the composition of stream’ s ecosystem service function, the service values for provisioning, regulation, support and culture are 273.56,75.72,4.0 and 3.08 billion Yuan RMB,respectively. Obviously,the stream ’ s ecosystem service values mainly embody in provisioning service value and regulating service value. However, due to lack of measured approaches, the service values for research and education of the culture function are not estimated,which resulted in underestimation of provisioning service and regulating service values. Moreover, as each service function closely interact and influewcp the other service functions,this requires not only consideration of stream,provisioning service value,but also put more attention to the comprehensive values from other service functions. Otherwise,the whole stream,service value will be damaged. Furthermore, some effective protection measures should be put into effect when use stream water for so-cial-economic development of the Weihe River basin.
