摘要
西藏"一江两河"地区日趋严重的土壤退化是由其生态环境的脆弱性、地貌结构的特殊性,特别是人类影响和干预的广泛性、非合理性决定的。在阐述土壤退化类型、特征的基础上,就土壤退化的发生机制进行了综合分析。
The region of 'Three river' has rather peculiar landforms texture,climate conditions is complicated,ecological environment is weak,mankind using and exploiting of natural resources is provided with intense stereochemistry features. Soil degradation is tending to deteriorate along with the uninterrupted increasing human being's interference intensity and frequency.Mechanism of soil degradation is deeply analyzed on the basis of the discussion the type and internal characteristics of soil degradated.
