摘  要:
收集了2002~2011年舟山近岸海域生态环境监测数据,分析了舟山近岸海域生态环境基本变化及其成因。结果显示,近10年来舟山近岸海域海水水质日益恶化,海水盐度和悬浮物浓度呈现逐年上升趋势,部分海域海水化学需氧量、石油类含量超出国家海水水质标准的一类海水标准,无机氮和活性磷酸盐超标非常严重,只达到四类、劣四类海水标准,导致赤潮现象频繁发生。沉积物环境质量和海洋生物资源保持良好,沉积物各项指标基本达到一类海洋沉积物标准,海洋生物资源较为丰富。导致舟山近岸海域污染的主要原因是入海污染物的排放、海水养殖污染以及船舶溢油污染等。

摘  要:
This research represents an analysis of ecological environment changes and its trends based on a great deal of observation data and information of Zhoushan coastal waters from 2002 to 2011. It shows that salinity and suspended solid concentration had a slight increase,COD and oil concentration were out of the First Class of National Seawater Quality Standards for China,especially the inorganic nitrogen and relative phosphate concentration even reached the Forth Class which lead to common occurance of red tide. In addition,the marine sediment environment maintained good quality and marine biological resources were not obviously damaged. The primary causes of deterioration of coastal waters in Zhoushan are pollutants emission from coast,mariculture pollution,ship oil spill pollution and so on.
