摘　　要：以新疆地区为例,分析了该区土壤盐渍化的形成过程、类型及土壤盐渍化的原因。气候、土壤类型以及人为因素是土壤盐渍化形成的主要原因。以塔里木河流域实施竖井排灌工程的成功实例,证明竖井排灌效果。通过对竖井排灌作用机理分析及其与土壤盐渍化的关系研究,论证了在新疆地区采取竖井排灌工程的可行性和必要性。提出竖井排灌和明渠排水相结合的灌溉方式,作到合理开发利用水资源,改善生态环境。According to the example of Xinjiang, based on the analysis of the forming and types of salinized soil and the reasons of soil salinization,the authors put forward that the main reasons which lead to salinization are climate,agrotype and man\|made factors.Taking the drainage areas of Talimu as successful examples,analysing the mechanism of salinization it is proved that the shaft irrigation and drainage are effective.Finally the authors put forward the composed irrigation way of shaft irrigation and drainage with bright trench drainage in order to utilize water resource in reason and improve enviroment.
