摘要： 本文通过对海南省不同割龄暗红湿润铁铝胶园地的土壤肥力进行评价分析，其评价结果表明，海南省不同割龄暗红湿润铁铝胶园的土壤肥力普遍较低，综合评价指标值介于0.24～0.50之间。不同割龄湿润铁铝胶园土壤综合评价指标值大小，0～10年（0.26）＞30～年（0.24）＞10～20年（0.23）＞20～30年（0.23），且各割龄段综合评价指标值都低于0.4；不同纬度湿润铁铝胶园土壤综合评价指标值大小，海口（0.35）＞临高（0.25）＞澄迈（0.24）＞文昌（0.23）；不同经度湿润铁铝胶园土壤综合评价指标值大小，定安（0.50）＞海口(0.35)＞琼海（0.34）＞万宁（0.23）。且不同割龄，不同地区综合肥力都较差。

Abstract: This paper evaluates the soil fertility of dark red humid ferralsol for rubber plantation in Hainan province. The evaluating results indicate the soil fertility of dark red humid ferralsol for rubber plantation is low in different tapping years, and the integrated evaluation index is from 0.24 to 0.50. In different tapping years, the integrated evaluation index of soil fertility is 0～10 years（0.26）＞30～years（0.24）＞10～20 years（0.23）＞20～30 years（0.23）, all of these are under 0.4. In different latitude, the integrated evaluation index of soil fertility is Haikou（0.35）＞Lingao（0.25）＞Chengmai（0.24）＞Wenchang（0.23）, and in different longitude is Dingan（0.50）＞Haikou（0.35）＞Qionghai（0.34）＞Wanning（0.23）. The integrated soil fertility in different tapping years and region is inferior.
