摘要
本文根据土地退化的成因与特点，将我国土地退化分为水土流失、土地沙化、土壤盐碱化、土地贫瘠化、土地损毁６大类，并总结出我国土地退化的３大特点：①发生广，类型复杂，区域差异明显。②发展快，并具有一定的阶段性。③强度大，生态、社会后果严重。在此基础上提出了防治土地退化的有效对策。
Six types of degradated land are categorized as soil erosion, land desertification, soil salinizatiollalkalization, land impoverishment and land destruction according to the origin and characteristics of land degradation. Three principal characteristics are recognized as ① widespread in development with complicated types and distinctive areal differentiations; ②fast in development with certain periodicity and ③ high in intensity with serious ecological and social consequences. Countermeasures for effective prevention and control of land degradation are raised accordingly.
