【Aim】 The Gaoligong Mountains serving as the vital ecological security barrier in southwest China are rich in biodiversity and hold high ecosystem service value. The impacts of climate change and human activities have led to serious invasion of alien plants in the Gaoligong Mountains. Clarifying the spacial correspondence between the distribution characteristics of alien invasive plants and important areas of ecosystem services could make contribute to the prevention and control of alien invasive plants and the construction of Gaoligong Mountains ecological security barrier. 【Method】 This study valuate ecosystem services value with equivalent factor method, and the importance classification and zoning are carried out at the scale of 3 km grid unit. The spatial distribution pattern of alien invasive plants in Gaoligong Mountains were analyzed by combining literature analysis and field investigation. Arcgis 10.2 software is used to analyse spatial correspondence between ecosystem service zoning and the distribution of alien invasive plants. 【Result】 Gaoligong Mountains were divided into five levels according to ecosystem services assessment, and water, broad-leaved forest, coniferous forest, shrub forest and shrub grassland are highest in value per unit area. There are 59 species of alien invasive plants in Gaoligong Mountains, and the numbers of species assessed as grade Ⅰ-Ⅴ are 12, 17, 8, 11 and 11. Excepting for the first level important area, all other areas are distributed with alien invasive plants, with the third and fourth level important areas (mainly shrub forest and farmland) having the most species of alien invasive plants. 【Conclusion】 Alien invasive plants are posing threats to supply of ecosystem services, and it is urgent to conduct a systematic investigation and evaluation of alien invasive plants to identify high-level invasive plants so as to implement differentiated control of alien invasive plants. The terrestrial alien invasive plants should be the focus of the study of alien invasive plants in Gaoligong Mountains; artificial shrub land and cultivated land, as the gathering area of invasive plants in Gaoligong Mountain, should focus on the prevention and control of alien invasive plants..
