| 摘 要： | 新疆是我国重要的棉粮基地之一,但长期以来土壤盐碱化与次生盐碱化一直是制约农业发展的关键因素之一。在阐述土壤盐碱化区域分布与特点的基础上,分析了盐碱土发生的自然因素与人为因素,并基于干旱区所特有的生态系统的宏观地带性规律,着重指出了在土地利用布局、渠系利用效率、过量灌溉、排水不足等4个方面存在的问题,最后给出了相应的建议。

| Abstract: | Xinjiang is one of the main regions that produce cotton and foodstuff in the country and its agriculture has been markedly affected by soil salinization for a long time. On the basis of the regional distribution and characteristic presented,natural and human factors influencing development of soil salinization were analyzed. It was pointed out that there exist four main problems with the development of salinized soil: geographical layout of land use,low efficiency of the canal systems,excessive irrigation,and lack of drainage planning. Corresponding countermeasures were proposed. |
