Abstract: The coastline of the Three Gorges Reservoir area has many functions and is an important carrier for the construction of national economic facilities such as ports,wharves,roads and Bridges. The scientific and rational use of coastline resources is particularly important for regional economic development. Through the analysis,the main categories of shoreline utilization projects in the Three Gorges Reservoir area are clarified,and the benefit evaluation systems of port shoreline utilization projects,flood control and bank protection and ecological improvement projects in the Three Gorges Reservoir area are constructed respectively,and the corresponding benefit quantitative calculation models and estimation methods are put forward. The benefit quantitative evaluation and analysis of port shoreline utilization projects flood control and bank protection and ecological improvement projects in typical districts and counties of the Three Gorges Reservoir area are realized. This method system can provide reference for scientific planning,high quality and efficient development and utilization of the reservoir shoreline resources,ensuring the good ecological environment and promoting the sustainable development of the reservoir society and economy.
