土壤盐渍化研究现状及未来研究热点

随着全球气候暖化问题的日益加剧, 土壤盐渍化问题已经成为各国关心的全球性问题, 全球约有7%的土地受到盐渍化的威胁, 而且这个数字还在上升。我国是土壤盐渍化比较严重的国家, 盐渍化土壤面积大, 分布广, 对区域农业发展构成了严重的威胁。本文对70 年来我国土壤盐渍化研究的内容框架进行了梳理和概括, 并结合国内外的相关研究成果对已有研究中存在的不足进行了评述;借助文献数据库和相关数据共享网络对近30 年来国内外盐渍土研究的趋势和总体概况进行了总结, 提出了新形势下土壤盐渍化研究的5 个重点领域和方向, 旨在为今后开展盐渍土研究提供新的思路。

The Present Situation and Hot Issues in the Salt-affected Soil Research

With the global warming,soil salinization has become a global concern in the world,and about 7% of the global land is threatened by salinity.In addition,this figure is rising.Soil salinization in China is critical,and the area of salt-affected soil is vast,which poses a great threat to agricultural development.This study summarizes the framework of the soil salinization research in China over tha past 70 years,and make comments on the inadequencies in previous studies at home and abroad.This study summarizes the present situation and future tendency of soil salinization research across the world in the last 30 years by using the literature database and data-sharing network,and identifies five research priorities and orientations for providing new ideas to carry out the saline soil research in the future.
