摘要
土地盐渍化、沼泽化是受生物、气候、地质、地貌、水文和水文地质等因素综合影响的地质灾害。本文结合“中国土地盐渍化、沼泽化图(1:600万)”,讨论了我国土地盐渍化、沼泽化的分布特点及发生发展过程。同时考虑人为因素和自然因素对土地盐渍化、沼泽化的综合影响,圈定了土地盐渍化、沼泽化潜在威胁区,从而预测土地盐渍化、沼泽化的发展演变趋势。
Soil salinization and soil swamping are geological hazards. They are influenced by climate, biology, geology, terrain, hydrology and hydrogeology. On the basis of 'Map of Soil Saliniza-tion and Soil Swamping in China (1 : 6, 000, 000)', the distribution characteristic and developing process of soil salinization and soil swamping in China are discussed in the paper. Consid-ered the influence of human and natural factors on soil salinization and soil swamping, the paper also defines the potential areas of soil salinization and soil swamping in China. Thus, the evolution trend of soil salinization and soil swamping is predicted.
