长江口及其邻近海域悬浮物浓度和浊度的对应关系

Corresponding relationship between suspended matter concentration and turbidity on Changjiang Estuary and adjacent sea area

长江三峡工程一期蓄水自2 0 0 3年6月1日开始,到6月10日结束.为了研究长江三峡工程蓄水对长江口环境的影响,在2 0 0 3年6月15日至6月2 4日期间组织了长江口及其邻近海域环境的综合调查.根据该次调查所取得的悬浮体浓度和浊度的实测资料,探讨了不同水体中两者可能存在的相关性,以期达到根据易得的浊度数据获得更多悬浮体浓度分布规律的目的.同时,分析了两者关系的主要影响因素和关系式的适用范围.结果表明:长江口及其邻近海域不同水体悬浮体浓度和浊度之间均存在有较好的相关性。

The first-stage storage of the San Xia Project started on the 1^(st) June,2003 and ended on the 10^(th) June. In order to investigate the influences of the San Xia Project on the Changjiang estuary and adjacent sea area environment, a cruise was carried out to synthetically study the environment and suspended matter distribution from the 15^(th) June,2003 to the 24^(th) June. In this papers, corresponding relationships between total suspended matter and turbidity in different water bodies are discussed based on recovered data so that much more characteristics of suspended matter distribution can be understood in terms of easily-obtained turbidity data. The factors affecting on the relationships and the scope of application of the relationship formulas are concerned as well. In results, fairly good relationships, logarithmically linear relationships, have been found between total suspended matter and turbidity in different water bodies.
