以贵州喀斯特中心普定站土壤检测数据为基础,通过分析不同石漠化等级条件下土壤质量特征,探讨土壤质量变化与石漠化等级间的关系,揭示不同石漠化程度下土壤理化性质的变化规律.结果表明:(1)毛管孔隙及自然含水量随石漠化程度的加重而降低;(2)土壤饱和导水率随着土壤侵蚀程度的增加而增加;(3)土壤容重随着石漠化程度加剧而增大;(4)石漠化程度与土壤养分状况关系紧密,石漠化程度越高,土壤有机质、氮、磷、钾等养分含量越低.

The article discusses the relationship between soil and desertification through analyzing soil regime during desertification process on the basis of data from Puding station of Guizhou karst center. The results indicate that (1) capillary porosity and natural moisture content of the soil decreases as the rocky desertification intensifying; (2)saturated hydraulic conductivity of the soil increases with soil erosion; (3)bulk density of the soil generally increases with the grade of rock desertification; (4) there is a close relationship between desertification and soil nutrient status, and the higher the grade of rock desertification,the lower the soil organic matter, nitrogen, phosphorus, potassium and other nutrient content.
