土壤盐渍化及治理研究进展

Research Progress on Soil Salinization and Management

  • 摘要: 随着全球资源环境问题日益凸显,土壤盐渍化受到广泛关注,全球约有8%的土地受到盐渍化的威胁。我国是土壤盐渍化比较严重的国家,盐渍土面积占全球盐渍土面积的1/10,且近年来在自然和人为因素等条件影响下,受盐渍化胁迫的土壤还在不断发展,严重影响耕地资源、作物产量、农业发展等其他方面。因此,采用经济合理高效的治理措施改善盐渍土壤质量和提高作物的产量具有现实意义。总结了土壤盐渍化的成因及来源,从灌排措施、物理调节、化学改良、生物措施这4个方面综述了盐渍化土壤的治理途径,为进一步开展盐渍土的治理研究提供参考。

     

    Abstract: With global resources and environmental problems becoming more and more prominent, soil salinization has received widespread attention, and about 8% of the world’s land is threatened by salinization. China is a country where soil salinization is relatively serious, and the saline soil area accounts for 1/10 of the global saline soil area, and in recent years, under the influence of natural and human factors and other conditions, the soil under salinization stress is still developing, which seriously affects other aspects such as arable land resources, crop yield, and agricultural development. Therefore, it is of practical importance to improve the quality of saline soils and crop yields using economically rational and efficient management measures. This paper summarizes the causes and sources of soil salinization, and reviews the management pathways of saline soils from four aspects: irrigation and drainage measures, physical regulation, chemical improvement, and biological measures, to provide references for further research on saline soils management.
