Résumé partiel
Northwest Arid Region scarce rainfall,strong evaporation,water resource shortage,ecological environment is fragile,the surface runoff is scarce and unevenly distributed and a series of characteristics of water resources,the groundwater becomes the basic condition for the formation of the ecological system in arid area oasis development and stability and the decisive factor is the key factor affecting the ecological environment.In order to alleviate the shortage of water resource in northwest arid region economic development,water conservancy project is bound to increase the development of water resources,after the operation of the project will affect the downstream groundwater flow and water resources,further impact on the local ecological environment,such a move will affect the body and cause damage to the local ecological environment is an urgent problem.The water source project of a complex water transfer project in inland arid region was taken as an example.FEFLOW software was used to establish numerical simulation model of groundwater flow in study area,in order to predict groundwater level changes and the impact groundwater sources in river valley after the project is going to completed.At the same time,based on the vegetation distribution map of remote sensing interpretation,to obtain the ecological water level distribution through the calculation of vegetation ecological water demand and ecological water consumption intensity.After comparison,the size and direction of different forest and grass from the ecological water level were obtained,and the regulation water quantity is calculated
