Yilong Lake is the southernmost plateau freshwater lake in China. The health of its watershed ecosystem is of special strategic significance to maintain the ecological security and ensure the sustainable development of regional economy and society. This paper analyzed the characteristics of landscape type in Yilong Lake Basin of 1990, 1995, 2000, 2005, 2010, 2015 and 2018 and discussed the impact of landscape pattern type changes and its effect on ecosystem services values (ESV). The results showed that: (1) The landscape types of Yilong Lake are mainly forest land and the largest dynamic degree of comprehensive 1andscape type in the six stages is 2010–2015 and the smallest is 2015–2018. (2) Spatially, the most frequent conversion was arbor forest land, which turned to shrub forest land and garden land. The rapid expansion of construction land and transportation land were turned by cultivated land area. (3) Temporally, from 1990 to 2018, the total ESV also increases year by year, and the regional distribution of high ESV is consistent with the distribution of water areas and gardens. The comprehensive analysis shows that the implementation of governance projects such as ecological protection and governance of Yilong Lake surface mountain are conducive to increase the landscape types and the total ESV.
