调查研究了福建省主要海岛土壤资源的类型、面积、分布及其肥力状况．全省主要岛屿土壤资源总面积为７４０１３．５ｈｍ２，占调查岛屿土地总面积的７２．９７％，分属５个土纲６个土类，以赤红壤、滨海盐土和风沙土为主，占土壤资源总面积的７５．９０％．海岛土壤有机质含量偏低，普遍缺Ｎ，Ｐ、Ｋ水平较高，呈微酸性反应，质地偏轻，保肥供肥能力弱．在分析土壤资源利用现状和存在问题的基础上，进一步探讨了全省主要海岛土壤资源合理利用的对策
The types, area, distribution and fertility status of soil resources in the main island of Fujian Province were investigated. The total area of soil resources of the main islands in the province is 74013.5hm2, accounting for 72.97% of the total area of the surveyed island land, belonging to 6 soil types of 5 soil types, with red soil, coastal saline soil and aeolian sandy soil, accounting for soil 75.90% of the total area of resources. Soil organic matter content of the island is low, the general lack of high levels of N, P, K, was slightly acidic reaction, the texture is light, weak fertilizer and fertilizer supply. On the basis of analyzing the current situation and existing problems of soil resources utilization, this paper further discusses the countermeasures of rational utilization of soil resources of the main islands in the province
