摘要

摘要: 流域水体管控单元划分是实现流域水生态环境差异化管理的基础。基于小流域特点，结合水质参数、水生生物多样性等多要素指标，提出了一种水体空间管控单元划分方法。在此基础上，利用模糊层次分析法对各管控单元的优先级进行评价，揭示出小流域水生态环境质量与潜在污染来源的关联关系。以四川南河小流域为例，划分出3个管控区段和21个水体管控单元，识别出6个极高的管控单元，4个极低的管控单元，为指导小流域多尺度、精细化管理提供了参考。

Abstract: The division of water control-unit for watershed is the basis to implement diverse water eco-environmental management. Combining a series of criteria, including characteristics of small watershed, corresponding water quality, aquatic biodiversity etc, a water body control-unit division approach was proposed. Fuzzy analytic hierarchy process (FAHP) was employed to rank the management priority for each control unit, and thus revealed the nexus between the quality of water ecological environment and the potential pollution source. By taking Nanhe river as a typical case, three control sections and twenty-one water control-units were divided. There were six extremely high control-units and four extremely low control-units identified, which laid a foundation to lead multi-scale and precise management for small watershed.
