The interbasin water transfer project has realized the optimal allocation of water resources, improved economic benefits, improved people's life and welfare, and had an impact on the ecology. Taking Anhui Jianghuai water transfer project as an example, this study uses morphological spatial pattern analysis (MSPA) to identify the core area, selects the patches in the core area, identifies the source according to the patch importance index, constructs the basic resistance surface according to the resistance factor, modifies the basic resistance surface by using the landscape connectivity index, and constructs the ecological corridor by combining the minimum cumulative resistance (MCR) model and the loop model (curve) to build the ecological network of the completed Huaihe River Water Transfer Project (Anhui). The results show that there are 83 sources, 197 potential ecological corridors, and 80 ecological nodes in the ecological network of Anhui Jianghuai project. Ecological network optimization strategies and protection suggestions are put forward for ecological sources, ecological corridors, and ecological nodes, respectively, so as to provide scientific reference and basis for the ecological environment protection and high-quality development of Anhui Jianghuai water transfer project.
