摘　　要：通过调查取样分析 ,结果表明 :海南菠萝园土壤表层石漠化趋势明显 ;土壤中有机质、全氮、碱解氮和速效钾含量与自然植被区土壤比较 ,明显下降 。Based on the investigation and sampling analysis,the results showed that the tendency of petrification and desertification in soil surface layer was remarkable in Hainan's pineapple orchards.When a comparison was made between the sample soil and the contrast soil,the content of organic matter,total nitrogen,alkaline nitrogen,and quick acting potassium in sample soil obviously showed the tendency of decline.But the content of phosphorus and total potassium didn't show the tendency of decline.
