锦州湾泥沙运动的研究
符文侠, 刘国贤
国家海洋环境监测中心 大连 116023
摘要:
根据1985年春季和1986年夏季（洪水期）对锦州湾现场调查和室内分析资料计算的结果是，锦州湾沿岸河流在洪水期进入湾内泥沙量为7.46万t，全年为13.7万t；外海进入湾内的泥沙量在洪水期为8.22万t，全年为20.19万t。故洪水期进入湾内的泥沙量为15.68万t，全年为33.89万t．假如这些泥沙进入湾内作均匀沉积，则洪水季节沉积量为0.14 g／cm2，年沉积量为0.298 g／cm2。

STUDY ON SEDIMENT MOVEMENT IN JINZHOU BAY

Abstract:
This paper details results of a study on the silt soures, contents distribution, sectional discharge and accumulation conditions of the semi-enclosed and shallow Jinzhou Bay in the west coast of Liaodong Bay during 1985—1986.

Silt content:(a) was mean of 30 - 42 mg/L in spring, 16.55 mg/L in summer; (b) was maximum of 60.5 mg/L, minimum of 4.19 mg/L; (c) in shallow water was greater than that in deep water; (d) decreased from bottom to surface.

If the total silt input of 338.9 kt/a (137 kt/a from rivers, 201.9 kt/a from the outer sea) distributed in the Jinzhou Bay only, the sediment amount would be 0.298 g/cm2 deposited to a thickness of 5mm.
Key words:  Jinzhou Bay, Silt content, Sectional silt discharge, Silt reaccumulation
