摘　　要：根据坡度和地势强度变化,把地形分为8种不同的类别,并分析了海南省胶园土壤肥力特性在不同地形条件下的变化。结果表明,在不同地形条件下,胶园土壤pH、有机质、土壤氮素、土壤磷素、土壤钾素存在一定程度的差异,但总体上,地形条件的变化与土壤性质之间的变化并没有明显的线性关系。According to the change of slope and hypsography intension, the 8 terrains were distinguished. Then, the relations of terrains and the status of soil fertility were studied. The studied fertility indices included soil pH, the contents of soil organic matter, soil Nitrogen, soil phosphorus, and soil Potassium. The results indicated these soil fertility indices had changed definitely in different terrain types, but there were not linear relations between the changes of terrain conditions and the soil fertility characteristics.
