大安古河道盐碱土类型与开发利用模式研究

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

针对大安古河道盐碱土具有盐碱化黑钙土、盐碱化草甸土、盐碱化沼泽土、盐土和碱土类型的特点,实施盐碱化黑钙土改土培肥、盐碱化沼泽土和轻度盐碱化草甸土种稻、盐碱化沼泽土和湖泡育苇-养鱼、盐碱化草甸土围栏封育恢复草原、盐土和碱土种植碱蓬及碱茅等多种开发利用模式,可遏制其盐碱化的发展,改善生态环境,实现经济、生态和社会效益的协调发展。

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.
