盐渍化土壤改良的研究进展

Research Progress in Amelioration of Saline- alkali Soil

我国盐渍化土壤广泛分布在干旱、半干旱地区。研究盐渍化对我国农业可持续发展、提高盐碱地的生产能力和维持良好的生态经济效益具有举足轻重的作用。该研究介绍了国内外学者提出的盐渍化土壤的成因、危害以及盐渍化土壤改良措施的最新研究成果,分析了盐渍化对植物的毒害机理。并且,结合目前相关研究的前沿和热点问题,提出我国盐渍化土壤的研究前景,为进一步完善盐渍化土壤改良措施提供理论依据。

In China,saline land is widely distributed in the arid and semiarid regions.The studies of poison effect on plant and amelioration measures will play a vital role in maintain a good ecological economic efficiency in sustainable agricultural development of China.This paper in troduced the causes and hazards of the saline land and the latest achievements in the amelioration measures of the saline land.It analyzed the mechanism of poison effect on plant.In combination with frontier and hot issue on studies of saline land,it presented research prospect of saline land.It is expected that this study will provide a good theoretical guideline for the amelioration measures of saline land.
