在新疆这样的干旱地区，水的分布与运移，严重影响盐分在地区上的重新分布，而盐分在特定地区的积累与消退，直接关系到土地资源的持续开发乃至国计民生，现代水资源评价及开发利用中，首先需要定量描述水盐分布、运移及人类活动对其的影响做出预测，水盐平衡模型对解决这类问题，提供了有力的手段。
In arid regions such as Xinjiang, the distribution and migration of water seriously affect the redistribution of salinity in the region. However, the accumulation and regression of salinity in a particular region are directly related to the sustainable development of land resources and even to the national economy and the people’s livelihood, evaluation of modern water resources and In the development and utilization, we first need to quantitatively describe the effects of water and salt distribution, migration and human activities to make a prediction. The water-salt balance model provides a powerful solution to these problems.
