中文摘要	采用多种指标和方法对沙井子灌区农田排水进行了灌溉用水水质评价,结论表明:(1)该排水不能直接用于农田灌溉,在砂性土壤和冲洗、排水条件好的情况下,与淡水混合后,在作物耐盐碱较强的生育阶段可作为灌溉水源;(2)该排水可以用来灌溉天然植被,作为生态用水水源;(3)碱度、盐度、矿化度法,综合危害系数法,灌溉系数法和水土保持综合法,适用于塔里木盆地的灌溉用水水质评价,判别公式法有待进一步检验.
英文摘要	The Shajingzi Irrigated Area is located in the southern piedmont of the Tianshan Mountains, the northwest-ern marginal zone of the Tarim Basin, and the alluvial deltas of Aksu River, Yarkant River and Hotan River. It belongs to the warm-temperate continental desert climate, the region is rich in sunshine resources but in serious shortage of water resources. The water consumption of agriculture and animal husbandry relies completely on the channeled water from the Aksu River, and the annual volumes of the channeled water and the drained water from farmlands are 1. 387 x 109 m3 and 2. 2 X 10 m respectively. The drained water is not only a waste of water resources, but also pollutes the stream wa-ter of the Tarim River. Therefore, the drained water must be controlled and managed by moderately enlarge the irrigated area of artificial ecology, thus, the groundwater level can be depressed, the soil salinization can be alleviated, the water-salt balanced can be maintained, and the water resources can be rationally utilized. In this paper, the irrigation water quality in the Shajingzi Irrigated Area is evaluated by using some indexes and methods. The results are as follows: (1) The drained water from farmlands can not be directly used as irrigation water, after it is mixed with fresh water, it can be used to irrigate the salt-tolerant plants or crops under the conditions of sandy soil and fine drainage; (2) The drained water can be used to irrigate the natural vegetation; (3) The indexes and methods including the salinity, alkalinity, de-gree of mineralization, synthetic harmful coefficient, irrigation coefficient, water and soil conservation, are applicable in evaluating the irrigation water quality in the Tarim Basin.
