内陆干旱平原区盐碱地改良利用区划研究——以新疆焉耆县平原灌区为例

Study on the Utilization and Improvement Zoning of Saline Land in Inland Arid Plain Area

本文以新疆焉耆县平原区为例,选取控制盐碱地形成和改良利用难易程度的包气带岩性、地下水埋深、地下水矿化度、0～60cm土壤含盐量等4个主导因子,在分级赋权的基础上,对4个主导因子进行叠加分析,对盐碱地改良利用区划进行了有益的尝试。

Taking the plain area of Yanqi County, Xinjiang as an example, the lithologic characters of unsaturated zone, the groundwater depth, the mineralization degree of groundwater and the salt content in 0-60cm soil layers are selected as the dominant factors to control the formation and the utilization and improvement of saline land. Based on the grading weights, the stacking analysis for the 4 dominant factors is made and the beneficial study is carded out in the utilization and improvement zoning of the saline land in the area.
