[Objective] Taking Xingyun Lake in Yunnan Province as an example, the lake health evaluation, with basin impact factors were taken account to provide reference and demonstration for the health evaluation of the plateau lakes in Central Yunnan Province.[Methods] Based on the investigation and analysis of the driving factors of the lake condition, considering the influence of the impact factors from the basin scale on the lake environment, the revised evaluation index system of the plateau lake considering the basin impact factors was constructed, and the specific quantitative evaluation and characteristics of recognition of Xingyun Lake health status in Yunnan Province were carried out under the support of remote sensing and GIS technology.[Results] The quantitative values of the evaluation indexes under the 5 criterion layers of the Xingyun Lake that include hydrology and water resources, the physical structure of the lake, the water quality, the biological and social service functions were obtained. The overall health status of the Xingyun Lake belongs to the general level. The main constraints originated from water quality, biological, hydrology and water resources.[Conclusion] The assessment index system and method used in this work overcome the spatial scale restriction that conventionally understand and assess lake degradation problem only from the lake itself and the subsequent insufficient consideration about driving indexes problem. The method and technique applied in the Xingyun Lake health evaluation will give benefit to other plateau lake assessment in Central Yunnan Province.
