Abstract. Lake Basin pollution has become an important environmental problem, exploring its landscape pattern of land use and eco-environment characteristics is of great significance for environmental pollution control. Through the analysis of the landscape pattern indices of diversity,
... diversity, evenness, dominance and fragmentation of the three lake basins in Yunnan province of China, and based on the evaluation results of the ecological environment of the lake basins, to explore the relationship and characteristics between the landscape pattern of land use and its ecological environment. Research indicates: (1) According to the analysis of landscape pattern of land use in the basin, the level of landscape diversity and evenness in the Fuxian Lake Basin is the highest, followed by the Erhai Basin. However, the lowest is in the Dianchi Basin; the degree of landscape fragmentation in the Dianchi Basin is the highest, followed by the Fuxian Lake Basin, and the lowest in the Erhai Basin. (2) According to the results of the ecological environmental quality assessment, Dianchi Basin is the worst, while the Erhai Basin and Fuxian Lake Basin are better, and the Fuxian Lake Basin is the best. (3) The landscape pattern of land use in the basin is closely related to the quality of the ecological environment. Basins with good ecological environment quality have a relatively high degree of diversity and evenness, and relatively low fragmentation; in the basins with poor ecological environment, the degree of evenness and diversity of landscape are relatively low, and the degree of landscape fragmentation is relatively high.
