摘要:
盐渍土在我国广泛分布,西北、华北、东北及沿海是我国盐渍土的主要集中分布地区,耕地中也有大量盐渍化土壤分布。盐渍土是我国最主要的中低产土壤类型之一,人类活动对其作用明显。本文回顾了我国盐渍土研究工作的发展历程,分析了我国目前盐渍土相关研究工作的现状和近期主要研究工作进展,并结合目前国内外相关研究的前沿和热点问题,提出了我国盐渍土研究的展望。建议重点进行土壤盐渍化评估和预警、土壤水盐运移过程及其模拟、植物与土壤盐分相互作用机制、土壤水盐优化调控、盐碱障碍治理与修复和盐渍化的生态环境效应等方面的研究。
关键词:  盐渍土  盐渍化  水盐调控  治理  修复

DEVELOPMENT AND PROSPECT OF THE RESEARCH ON SALT-AFFECTED SOILS IN CHINA
Yang Jingsong
Abstract:
Salt-affected soils are extensively distributed in Northwest,North,Northeast and coastal regions in China,and large areas of arable land are salt affected as well. So they are one of the most important low-yield types of soils. Apparently under influences of human activities,their productivity is closely related to their quality. While reviewing the development of the study on salt affected soils in China,the paper analyzed the status quo of the research and recent advancement in major fields of the study,and discussed prospects of the study by referring to the frontiers and hot spots of relevant researches both at home and abroad. The paper also suggested that emphasis be laid on topics of assessment and forecast of prediction of soil salinization,soil salt-water regime and modeling,mechanism of the interaction between plant and soil salt,optimal regulation of soil salt-water regime,management and remediation of soil salinity,eco-environmental impacts of salinization,etc.
Key words:  Salt-affected soils  Salinization  Salt-water regulation  Management  Remediation
