新疆是我国最为干旱的地区,没有灌溉就没有农业。在缺乏完整的排水系统情况下,不合理的灌溉,会极大地加重原有盐碱地的盐渍化程度,和产生新的土壤次生盐渍化。据历次考察统计,新疆荒地土壤资源约一亿伍千万亩。其中,轻和非盐碱化土壤面积约占26.6％,盐碱化土壤面积约占42.8％,难利用和不易利用的土壤面积尚有30.6％。在现有四千七百万亩耕地中,土壤次生盐渍化面积约占三分之一。 因此,为了发展农田灌溉,就必须对新疆干旱内陆域水文地质特征,及其对水利土壤改良的影响进行深入的系统研究。
Xinjiang is one of the most arid areas in our country and there is no agriculture without irrigation. In the absence of a complete drainage system, irrational irrigation can greatly aggravate the salinization of the original saline-alkali soil and generate new soil secondary salinization. According to previous inspection statistics, Xinjiang’s wasteland soil resources of about 100000000 mu. Among them, light and non salinized soil accounted for about 26.6%, salinized soil accounted for about 42.8%, difficult to use and not easy to use the soil area is still 30.6%. In the existing 47 million mu of arable land, soil salinization area accounts for about one-third. Therefore, in order to develop farmland irrigation, we must conduct an in-depth systematic study on the hydrogeological features of the arid inland area in Xinjiang and its impact on water conservancy and soil improvement.
