摘要: 通过比较不同地区的无瓣海桑Sonneratia apetala人工林土壤理化指标特征,探讨无瓣海桑人工林不同深度土壤理化性质的变化规律及其相关性。以淇澳岛红树林自然保护区与台山市烽火角两个不同地区的无瓣海桑人工林为例,测定0~100 cm垂直方向上土壤总氮、总磷、pH、电导率、有机碳含量等土壤理化指标,并进一步分析其相关性。结果表明,淇澳岛土壤的理化指标在垂直方向上总氮、总磷、含盐量、电导率、有机碳和容重随土壤深度的变化较烽火角要平缓,其中烽火角的含盐量、pH均显著高于淇澳岛;淇澳岛的总氮与电导率却高于烽火角。在0~15 cm和15~30 cm土层,烽火角的有机碳含量显著高于淇澳岛,在30~100 cm土层则显著低于淇澳岛。烽火角土壤全氮与含盐量呈显著负相关,与pH呈显著正相关。淇澳岛全氮含量与含盐量呈极显著负相关,与pH呈极显著正相关,并且有机碳含量与含盐量和pH呈显著相关性。

Abstract: To compare the characteristics of soil physical and chemical indexes in mangrove from different regions. We research the distribution and correlation of soil physical and chemical properties in two different regions mangrove plantations in Qi'ao Island and Fenghuojiao. Soil total nitrogen, total phosphorus, pH, electrical conductivity and organic carbon contents in 0–100 cm vertical direction were measured, and further analyzed their correlation. The results showed that the soil physicochemical indexes of Qi'ao Island in the vertical direction of total nitrogen, total phosphorus, salinity content, electrical conductivity, organic carbon and bulk density with soil depth change more gently than those of Fenghuojiao, and the salt content and pH of soil in Fenghuojiao were significantly higher than those of Qi'ao Island. The total nitrogen and conductivity of Qi'ao Island were higher than those of Fenghuojiao. In 0–15 cm and 15–30 cm soil layers, the organic carbon content of Fenghuojiao was significantly higher than that of Qi'ao Island, but lower in 30–100 cm soil layers. There was a significant negative correlation between total nitrogen and salinity content, and a significant positive correlation between total nitrogen and pH in Fenghuojiao soil. There was a significant negative correlation between total nitrogen content and salinity content, a significant positive correlation with pH, and a significant correlation between organic carbon content and salinity content, pH.

Key words: Sonneratia apetala, soil physicochemical properties, correlation
