| 摘 要： | 以广东某电厂煤码头为例，探讨临海煤码头落海煤尘对海洋环境的影响。文中阐述了点源和面源起尘量的估算。根据风速、煤粒下降速度、落差高度等计算煤码头扬尘入海量。依据煤尘煤粒到达海区的量计算煤尘入海引起海水悬浮物的增量等。文中还讨论了落海煤尘煤粒对海洋环境水质、沉积物和海洋生物的影响，认为其主要是对海水水质悬浮物、海洋生物光合作用以及沉积物有机质、硫化物含量的影响等。

| Abstract: | By taking the coal wharf of a certain power plant in Guangdong Province for an example, we inquired into the effects on the marine environment from coal dust of a coastal coal wharf. Tile paper expounds the estimation of coal dust quantity coming from the source point and source area. According to wind speed, falling rate of coal particles,falling difference heights and other factors, the quantity of raised dust from the coal dust that enter the sea is calculated. Then, increase of suspended matter into sea water caused by coal dust is calculated based on the amount of coal dust particles that reach the sea.The paper also discusses the effects from coal dust particles sunk in the sea to water quality, sedimentation and marine organism in the marine environment, and considers that it mainly affects suspended matter in sea water, photosynthesis of marine organisms, as well organic quality and sulphide contents in the sediments. |
