| 中文摘要: |
| 以海南省乐东县胶园土壤为研究对象，用GIS技术对2637 个样点0~40 cm土层土壤速效氮、磷和钾指标进行养分管理分区研究。结果表明，乐东县胶园土壤速效氮含量分4、5两个等级，速效磷含量分3、4、5、6四个等级，速效钾含量分4、5、6三
个等级，速效氮、磷、钾养分的分区数分别为2、4、3个，速效养分的综合分区包括15个分区类别1476个分区单元，各类分区的分布均较集中，非常有利于进行土壤养分的区域化管理。 |

| Based on collecting 2 637 samples of 0~40 cm soil layer and analyzing contents of theavailable N/P/K, the research was to define nutrient subarea of rubber plantation in Ledong by GIS method. The results indicated that content of available N(AN) had two grades of 4 and 5, available P(AP) had four grades of 3, 4, 5 and 6, available K(AK) had three grades of 4, 5 and 6. The subarea numbers of AN, AP, AK were 2, 4 and 3 respectively. The comprehensive zone of available nutrient included 15 categories, 1 476 subunit, the distribution of every categories being very mass and in favour of regional management of soil nutrients. |
