本文研究了 9810号台风影响下九龙江口及厦门西港表层海水颗粒有机碳 (POC)的变化特征及其与某些环境因子的关系。除厦门西港低潮水外 ,台风期间POC含量均迅速增大 ,此“冲击期”共维持 3d后POC值迅速回落 ,进入“恢复期”。台风期间 ,九龙江口高低潮、厦门西港高潮表层水POC含量分别为 0 .73 9、1.3 19和 0 .848mg/dm3 ,是非台风状况下的 1.1、1.9和 1.4倍 ,陆源有机物的输入和底质再悬浮作用是控制表层水POC含量的主要因素。而厦门西港低潮水POC含量受台风作用影响较小。碎屑POC为厦门近岸海域表层海水POC的主要组成部分。POC与溶解态N、P营养盐有一定正相关性 ,暗示其可能来自颗粒物中有机N、P的生物降解
In this paper, the variation characteristics of particulate organic carbon (POC) in the surface water of the Jiulongjiang Estuary and the Xiamen Western Harbor under the influence of the No. 9810 typhoon and its relationship with some environmental factors were studied. Except for the low tide water in the western harbor of Xiamen, the POC content rapidly increased during the typhoon period. After a total of 3 days, the POC value of the “shock period” quickly dropped to a “recovery period.” During the typhoon, the POC content of surface water at the Jiulongjiang estuary and Xiamen west port was 0.73 9,1.3 19 and 0.848 mg / dm3, respectively, which were 1.1, 1.9 and 1.4 times that of the non-typhoon condition. The input and sediment of terrigenous organic matter Resuspension is the main factor controlling POC content in surface water. However, the POC content of low tide water in the western harbor of Xiamen is less affected by the typhoon. Debris POC is a major component of POC in the surface waters of coastal waters in Xiamen. POC and dissolved N, P nutrients have a certain positive correlation, suggesting that it may come from the particulate organic N, P biodegradation
