摘 要：
红树林盐土是红树植被下的一类特殊土壤。雷州半岛红树林盐土各土层pH值为3.08 ~ 5.98,绝大多数低于4。土壤有机质平均含量为24.1 g/㎏,在土壤剖面中有机质含量分布没有规律性。土壤阳离子代换量为3.83 ~14.53 cmol/kg,平均6.94 cmo1/kg。土壤水溶性盐分7.6 ~ 42.1g/㎏,平均18.4 g/㎏,水溶性盐分有向下淋溶的趋势。土壤中<0.01 mm粒级含量一般>200 g/kg,土壤质地大多为中壤土类至中粘土类。

摘 要：
Mangrove solochak is a special type of soil under mangrove vegetation. Soil pH value varies from 3.08 to 5.98 with the soil layer in the mangrove solochak in Leizhou Peninsula, but often below 4. The average content of organic matter in the soil is 24.1g/㎏. There抯 no certain rule for distribution of organic matter in the soil profile. The cation exchange capacity in the soil ranges from 3.83cmol/kg to 14.53 cmol/kg, averaging 6.94 cmol/kg. The content of soluble salt varies from 7.6g/㎏ to 42.1g/㎏, with an average of 18.4g/㎏, showing a downward eluviation trend. The proportion of particles less than 0.01mm is usually more than 200 g/kg in the soil, and the texture of the soil is medium loam to medium clay.
