| Abstract: | The problem of ecological degradation of small and medium rivers in the northern plain area in China is prominent. The selection of appropriate ecological management technologies is conducive to improving the relevance and scientificity of river ecological restoration. In this paper, 21 river ecological management technologies in 5 categories were summarized. An index system, including 3 elements technical feasibility, economic rationality and governance effect and 9 indicators, were established. A screening method based on the comprehensive index and four-level screening criteria, described as very-suitable, suitable, sub-suitable, unsuitable was proposed to screen out ecological management technologies, and provide support for river ecological management. |
