Abstract

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.
- water classification,
- control-unit,
- aquatic ecosystem,
