Ecological management and control zoning aiming at the health maintenance of lake ecosystem has become an important means of water environmental protection and management. It is helpful to comprehensively grasp the ecological status of the basin and has important reference value for the sustainable development of the ecological economy in the basin. Taking Hongfeng Lake basin as an example, the lake ecosystem health was evaluted from five aspects:hydrological and water resources, physical structure, water quality, biology and social services. Using ArcGIS spatial analysis tools, taking 200 m×200 m grid as evaluation unit, this paper analyzes the spatial differentiation characteristics of watershed ecological sensitivity and ecological service function, and then uses Self-Organizing Feature Maps clustering method to optimize the optimal clustering scheme and divide the ecological divisions. The results show that:1) Hongfeng Lake ecosystem health score is 68.4, which is in a healthy state. The physical structure is a key factor threatening the ecosystem health of Hongfeng Lake. 2) The ecological sensitivity and spatial distribution of ecological service function of Hongfeng Lake Basin are obviously different, the ecological environment is fragile, and the service function of the ecosystem is low. 3) The Hongfeng watershed is divided into priority control area, key control area, buffer control area and general control area to implement differentiated management measures. The key task is to adjust the structure, change the mode, and gradually restore the ecosystem.
