揭示保亭县耕地土壤养分时空分布特征，为海南山区县市耕地土壤养分管理及土地可持续利用提供参考。采用实地调查、采集土壤样品和实验室分析相结合的方法，在测定土壤养分含量基础上，阐明土壤养分现状，并与保亭第二次土壤普查结果进行对比，探讨了全县耕地土壤养分时空变化规律。自20世纪80年代初以来，全县耕地土壤酸化明显，土壤有机质和速效钾含量有所下降、碱解氮变化不明显、有效磷含量显著升高，交换性钙、镁、有效硫含量中等偏下，各乡镇差异不明显，有效锌含量较丰富。保亭县耕地土壤养分含量属中等水平，且乡镇间各土壤养分含量分布不均，主要与施肥措施、气候条件及成土母质有关，其中施肥措施是最主要因素。

Spatial and temporal distribution characteristics of soil nutrients in tropical arable land of Baoting county in order to provide references for managing soil nutrients in tropical arable land of mountain area country. Based on the field survey, soil sampling and nutrient analyzing, soil nutrient status was studied and compared with the results of the Second Soil Survey. Spatial and temporal distribution characteristics of soil nutrients in mountain arable land were explored. Since the early eighty century, it indicated that the soil acidification was obvious in Baoting County. Soil organic matter and available K content had decreased slightly, but the effective phosphorus content significantly increased; nitrogen had no obvious change; exchangeable calcium, magnesium, sulfur content in the medium under, However, the contents of available Zn rich. The soil nutrient content in cultivated land in Baoting County was of medium level, soil nutrient content distribution is not uniform between the township, Mainly related to fertilization, climate conditions and soil parent material, wherein the fertilization is the most important factor.
