| 摘 要： | 本文利用海南省现有胶园202个0～20cm土壤混合样与海南省现有胶园相应的自然热带雨林、热带灌木草地的第二次全国土壤普查资料中的土壤剖面资料对海南省胶园土壤pH、有机质和NPK等土壤肥力质量指标的时空变异特性作了分析。分析结果表明，植胶后土壤pH、PK水平在时空方向上发生了显著改变。同时，植胶后各地区土壤pH、有机质含量和NPK水平变异系数均发生了不同程度的改变。

| Abstract: | 202 soil 0~20cm mixed samples of present rubber plantations and the second countrywide general soil survey profile data of the natural tropical rain forest and the tropical bush lawn soil corresponding to the present rubber plantations were used to analyze space-time variation characters of soil fertility quality indices, such as soil pH, soil organic matter, soil nitrogen/phosphorus/potassium，and so on. The results show the soil pH value and the content level of the phosphorus/potassium change remarkably, otherwise, coefficient variations of the soil pH value, the organic matter content, the content level of the phosphorus/potassium change differently after planting rubber tree in Hainan different regions. |
