摘　　要：应用ArcviewGIS与MODFLOW模拟了民勤绿洲2000年地下水位动态演化特征.将研究区划分为60×60网格,利用ArcviewGIS较强的图像资料处理能力,将各地下水埋深图、土地利用格局图等资料输入软件中,确定每个网格点的补给与排泄量,形成可供MODFLOW调用的数据元.根据民勤绿洲地下水水文地质条件划分应力期,利用MODFLOW软件模拟,模拟结果与实测数值比较吻合.Arcview GIS and MODFLOW is applied to simulate the change of groundwater in Minqin Oasis. The recharge and discharge of groundwater is a key problem in groundwater simulation. In order to solve this problem, the study area is divided into a mesh of 60 rows and 60 columns. Using Arcview GIS, the image files are input and transformed into the formation that MODFLOW can use. Then according to the features of discharge/recharge of groundwater in Minqin Oasis, the stress period is established. So we have the dates that MODFLOW need. In this simulation, only the WELL package is called by the main programme. The period of this simulation is from Jan. to Dec. 2000. The result shows that the simulation is successful and that the application of Modflow can predict the tendency of groundwater in Minqin Oasis and help us protect environment and properly use water resource. This paper can also serve as an example for MODFLOW applied in arid region.
