DISTRIBUTION CHARACTERISTICS OF SOIL NITROGEN AND PHOSPHORUS IN MANGROVE RESTORATION AREA OF COASTAL DEGRADED WETLAND IN QUANZHOU BAY
-
摘要: 对泉州湾滨海退化湿地红树林恢复区土壤总氮(TN)、总磷(TP)的分布特征进行了研究,结果表明:湿地修复后土壤TN、TP含量均高于湿地修复前,但与未种植植被样地相比,湿地修复可能在整体上降低土壤中TN、TP含量,且对TN含量的降低程度更加明显。不同修复模式下TN、TP含量不同,说明修复模式会对土壤TN、TP分布特征产生不同的影响。相关性分析表明,在泉州湾滨海退化湿地红树林恢复区,pH对土壤TN、TP含量有影响,土壤中TN与TP相互影响。Abstract: The distribution characteristics of soil total nitrogen (TN) and total phosphorus (TP) were studied in the mangrove restoration area of coastal degraded wetland in Quanzhou Bay. The results showed that both the content of TN and TP after wetland restoration was higher than that before the wetland restoration in the soil, but compared with the land without wetland, the reduction of TN content was more obvious. The content of TN and TP was different under different repair modes, which showed that different repair modes had different effects on the distribution characteristics of TN and TP in soil. Correlation analysis showed that the pH had an effect on the content of TN and TP in the soil, and TN and TP had mutual effect on each other.
