摘要
Soil salinization is extremely serious in the northern Yinchuan Plain of Ningxia since it is in an arid environment. Recently, shallow groundwater is used for agricultural irrigation because the runoff of the Yellow River water decreases from year to year. However, the utilization of groundwater may accelerate the process of soil salinization. In this paper, simulation model for soil salinization analysis is developed by using the PHREEQC software. The geo-chemistry processes of irrigation water and soil interaction axe analyzed to understand the principle of soil salinization under various conditions of water resources development and utilization in the plain.
