| 摘 要： | 根据2007年5月长江口及邻近海域春季调查资料,探讨了该水域水体总磷(TP)、溶解磷(DP)和颗粒态磷(PP)的空间分布特征及其环境影响因素。结果表明:各形态磷水平分布由感潮河段、河口向外海呈降低趋势。表层不同区域,各形态磷对TP贡献不同:长江口门内,以DP为主,占TP59.77%;长江口邻近海域,PP占TP比例稍高于DP。各形态磷分布受不同环境因素影响。

| Abstract: | Based on the investigation data in the Changjiang Estuary water and adjacent areas in May 2007,the various phosphorus distributions containing total phosphorus(TP),dissolved phosphorus(DP) and particulate phosphorus(PP) were studied,and the environment factors which affected the phosphorus distribution were discussed.The results showed that the horizontal distribution of phosphorus was decreased in the direction from tidal reach,mouth to coastal area.In the surface,the contributions of DP and PP to TP were ... |
