摘要
依据2002—2004年完成的“新疆平原区地下水资源调查与评价”成果，采用地下水资源模数法和GIS技术，确定了塔里木盆地平原区中盐度地下水（矿化度为2～3、3～5和5～7g／L）的分布状况，分布面积为92141．32km^2，占塔里木盆地平原区总面积的30．6％；计算了各流域、各地（州）中盐度地下水的补给资源量，总补给资源量为11．16亿m^3／a。分别采用单指标法（盐度S、可溶性钠含量SSP、镁系数KMg、残余碳酸钠RSC和钠吸附比SAR）、综合危害系数K和灌溉系数Ka法对中盐度地下水的水质进行了全面的评价，得出了各流域、各地（州）中盐度地下水的灌溉适应性评价结果。
In this paper, based on the results of Groundwater Resources Survey and Evaluation in X＇injiang Plain Areas （ 2002- 2004）, by using groundwater resources module method and GIS technology , the distribution of medium salinity groundwater（2 to 3, 3 to 5 and 5 to 7 g/L） in plain area of Tarim Basin, Xinjiang is determined. The total area is 92 141.32 km^2 ,accounting for 30. 6% of total plain area of Tarim Basin. Recharge resources quantity of each basin and each prefecture were calculated, the total recharge is 11.16 ×108 m^3/a. An evaluation of irrigation adaptability medium salinity groundwater is conducted by using the single index method, the synthetic harmful coefficient method and the irrigation coefficient method.
