The water diversion project in central Yunnan Province has a long water transmission line,a large scale of wa-ter transfer,and complex groundwater along the project.Tunnel construction had inevitably changed the water level and direction of groundwater,which may affect the structure and function of vegetation along the line.In order to explore the influence of groundwater level on vegetation in deep tunnel construction,two typical groundwater monitoring sites,Dali section and Chuxiong section were selected to analyze the characteristics of groundwater level change in typical monito-ring points,and the rainfall and evaporation in this area were analyzed by meteorological monitoring data.Combined with on-site sample investigation and UAV shooting,the vegetation change characteristics of the monitoring sites were ana-lyzed.The results showed that the vegetation around the two monitoring points was still in good condition at the end of the growing season,and the influence of groundwater level change on vegetation was limited under the comprehensive influ-ence of climate change and human activities such as engineering construction.The research results can provide a refer-ence for the ecological environment protection of tunnel construction.
