摘　　要：借助遥感方法，结合地下水水位观测数据，在区域尺度上定量地研究了我国黑河下游额济纳地区地下水水位埋深及与植被生长的关系。结果表明：影响植被生长的临界地下水水位埋深为4．0m，适宜植被生长的地下水水位埋深范围约为2．6—4．0m，当地下水水位埋深为2．8m左右时，植被长势最好。By combining the remote sensing method with groundwater observation data, the relationship between vegetation growth and groundwater depth in the Ejina area, which is located in the lower Heihe River basin, is studied. The results show that the appropriate groundwater depth for vegetation growth in this region is 2.6-4.0 meters, and the critical depth is 4 meters. The best vegetation growth occurs when the groundwater depth is about 2.8 meters.
