摘　　要：滇中引水工程输水线路长、调水规模大,工程沿线地下水复杂,隧洞施工不可避免地会改变地下水的水位和走向,进而可能影响沿线的植被结构和功能。为探索深埋隧洞施工地下水水位对植被的影响,选取滇中引水工程大理段、楚雄段的两个典型地下水监测点分析典型监测点地下水水位变化特征,通过气象监测数据分析研究区域的降雨和蒸发情况,结合现场样方调查、无人机拍摄等方法,研究了监测点的植被变化特征。结果表明:两个监测点位周边植被在生长季末期依然保持较好的状态,在气候变化和工程建设等人类活动综合影响下,深埋隧洞施工地下水水位变化对植被的影响有限。研究成果可为隧洞施工的生态环境保护提供参考。The water diversion project in central Yunnan Province has a long water transmission line,a large scale of water 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 monitoring 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 analyzed.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 influence of climate change and human activities such as engineering construction.The research results can provide a reference for the ecological environment protection of tunnel construction.
