课题研究主要从盐碱地现状与成因及灌区总体水盐动态分析两方面入手，阐述了灌区盐碱地、地下水位、地下水矿化度的分布规律，分析了灌区盐碱地的成因及变化趋势；根据灌区灌溉、排水条件与以上各种因素的关系，建立了灌区水盐均衡模型；把灌区作为一个均衡区，通过对黄河来水矿化度、灌区排水矿化度的分析，预测了在灌溉引水、排水减少时排水离子量的变化；运用灌区水盐动态模型原理，对灌区现状( 1998 、 2000年)与规划水平年总体水盐平衡进行了计算；总结分析了灌区水盐动态变化趋势，计算并提出了排水控制标准。 | | 7. | We summarize our results as follow : during the period of 1981 - 2000 , there was a great change of land use in the county . the area of arable land , forest and saline - alkali land increased ; water land and resident land changed a little ; the area of the grassland and wasteland decreased greatly
