Abstract：The long-term state or evolution of the relationship between vegetation and tourism activities is crucial to the sustainable development of the scenic area. At present， the research work in this field is not deep enough. Based on spatial information technology， the study takes the first batch of key scenic spots in the country-the Lushan Scenic Area as the research area. Long-time Landsat images were used to extract the NDVI changes in different regions of the scenic spot， and the impacts of tourism activities on vegetation changes were analyzed based on the data of tourist activities such as spatial distribution of tourists (Tencent regional heat map) and the size of tourists (number of tourists). The results showed that： in terms of spatial variation， as the distance from the core scenic spot increases， the vegetation increases at first and then decreases. The construction activities of the core scenic spots， the tourist activities of the main scenic spots， and the development around the scenic spots， inhibited the growth of vegetation； the areas with less tourist activities promote the growth of vegetation. In terms of temporal variation， the vegetation in the Lushan Scenic Area consists of two processes of decreasing at first and then rise， and the level of rebound at the end of the period is lower than the initial level. The overall trend is downward. The first change process is mainly related to the development and construction and tree type evolution in the scenic spots of Lushan Mountain. The second change process is mainly due to the rapid growth period of the number of visitors， and the ecological environment is still in the state of “overdraft”.
