摘要: 本文在回顾、总结的基础上,对中国农业科学院农业资源与区划所50年来盐碱土改良研究工作成果作一概述。内容包括:黄淮海平原盐碱土水盐运动规律特征,黄淮海平原土壤盐渍化的影响因素,气候、地下水、土壤质地、地形地貌、土壤肥力诸因素对土壤水盐运动的影响机理和黄淮海平原旱涝盐碱薄同时并存相互作用机理,及其总结研究提出的系列盐碱地改良技术和理论依据。50年来,盐碱地改良技术随着当时农业经济的发展由单项技术改良发展到黄淮海区域的综合治理阶段,这些技术都在生产上得到了应用,对当地的农业经济发展产生了重大影响。

Abstract: This article reviews and summarizes soil salinization researchs conducted in the Institute of National Resources and Regional Planning in the past 50 years. The contents are: the characteristics of the soil salinization water movement and salt transport, the effects of soil salinity in Huang-Huai-Hai Plain, such as climate, groundwater, soil texture and topography, soil fertility. And the effects of many factors on the characteristics of the soil salinization water movement and drought and salinization coexisting. A series of saline improvement technology and theoretical basis are proposed in the study. In the past 50 years, the improvmont technology of saline and alkali soil was developed with the local economic development from individual technical improvement to the Huang-Huai-Hai Plain comprehensive management stage. These technologies have been applied and had a major impacts on local agricultural ecnonomic development.
