针对内陆灌区次生盐碱化扩张和河流盐化等问题,本文以塔里木盆地土地开发为例,首先,阐述了阿拉尔段河流水质的演化过程和特点,通过对新老绿洲灌区土壤盐分状况和盐分运移特征的比较,初步揭示了垦荒导致次生盐碱化扩张和河流矿化度的机制;其次,通过对荒地冲洗盐分定额的计算与比较,初步评估了垦荒可能对塔里木河水质造成的影响;最后,基于灌区次生盐碱化控制和河流水质改善的目的,提出以水定地和多途径排水是达到上述目的的关键措施。

补充资料：土壤次生盐碱化
分子式：
CAS号：
性质：又称土壤次生盐渍化。原来非盐碱化的土壤由于不合理的灌溉或积涝而使土壤盐碱化的过程。不合理灌溉包括大水漫灌使地下水位升高，灌溉水含盐量较高，有灌无排，积涝即土壤长期被水浸泡，水不能排出，使地下水位升高。
