摘　　要：根据1：1万地形图和现状植被情况划分大西海子以下至台特玛湖适宜的保护范围。量算出10个区高程。水面线～地表面积的数值，推求得到的高程～水面线～面积关系曲线。若已知塔里木河下游某一点的水面线高程，就可以利用得到的公式求出与之对应的面积；根据已知地下水的埋深和植物根部最大能够吸收到的深度，就可以得出输水能够影响到的塔里木河下游植被面积，这对研究塔里木河下游生态环境的恢复状况有着很大的意义，是对应急输水改善生态量效果的评价的基础，也是塔里木河应急输水优化配置的重要一环。Divide below the Daxihaizi lake according to 1 ： 10000 topographic diagrams and the present situation vegetation situation the extent of protection which is suitable to the espoeially Taitema lake. Figures out the quantity 10 areas of the relations of elevation - water surface profile - area. Inferential reasoning obtains elevation - water facial suture - area relations curve, ff had known the lower Tafim fiver some water facial suture elevation, may use the formula which obtains to extract with it correspondence area; Depth most greatly can absorb whieh according to the known ground water burying depth and the plant root, may obtain the T lower Tarim fiver vegetation area which the water distribution can affect, this to studies the T lower Tafim fiver ecological environment the restoration condition to have the very big significance, is to the emergency water disrtibution improvement ecology quantity effect appraisal foundation, aLso is important foundation, the Tafim fiver emergeney water transported and water resources optimal allocation.
