Research on the types and exploitation models of saline soil in Da'an Ancient Riverway

Based on the characteristics of salinization about chernozem, meadow soil, bog soil, saline soil, alkaline soil in Da'an ancient riverway, the paper has established a series of models for exploitation of the saline soil in this area. Therefore the development of soil salinization can be controlled, and the ecological environment can be improved. The benefits of economy,ecology and society in regional development will be well coordinated.
