    摘要:

    为了客观有效地评价河流生态系统服务价值,高效开发利用河流水资源,基于河道内流量的特征和功能,揭示了河道内流量的生态系统服务效应;并根据河流生态系统的构成、特征、效用和功能,探讨了河流生态系统服务功能(价值)的概念和分类;最后,以河道内流量为量化指标,建立了河流生态系统服务价值评价模型,介绍了河流生态系统服务价值的价值量评价方法。研究成果以服务效应和评价模型方式揭示了河流生态系统服务价值与河道内流量之间的复杂函数关系,为河流管理部门高效开发利用和科学规划管理河流水资源提供新思路。

    Abstract:

    To objectively and effectively evaluate the service value of a river ecosystem and to efficiently develop and utilize river resources, firstly, the ecological service effect of instream flow is revealed based on its characteristics and functions. Then, according to its compositions, characteristics, utility and functions, the concept and classification of service functions(values)of the river ecosystem are discussed. Finally, taking the instream flow as the quantitative index, an evaluation model for the service value of the river ecosystem is established, and the evaluation method for its service value is introduced. The research results reveal the complex function relation between the service value of river ecosystem and the instream flow in terms of service effects and evaluation model, and this study may provide a new idea for river management departments to efficiently develop and utilize and to scientifically plan and manage water resources of rivers.
