- Abstract:
- Due to many subjects and fragmentation of construction projects, watershed water environment management often failed to meet expectations. In recent years, many cities have adopted PPP mode to comprehensively manage the watershed water environment. In order to achieve the effect of comprehensive management of watershed water environment, it is necessary to adopt systematic thinking to coordinate each sub-project at the beginning of the project. Combined with the practice of the PPP project for comprehensive management of water environment in the Neijiang section of the Tuojiang River watershed, the ideas and key points of the systematic implementation scheme are discussed from the macro and micro levels. On the macro level, taking Neijiang section of the Tuojiang River watershed as the research object, the existing problems including water environment governance, environmental quality, and management mechanism were analyzed from the large watershed scale. And the corresponding implementation schemes were put forward. The expected effect is evaluated by pollution load and model construction. On the micro level, taking Shouxi River as the research object, the problems of direct sewage discharge, agricultural non-point source and endogenous pollution in small watershed scale were analyzed. The corresponding implementation schemes were proposed, and the implementation effect evaluation was carried out. Thus, it can provide reference for other cities in China to carry out comprehensive water environment management.
