摘要
本文根据在大鹏湾盐田海域1990年3月30日至1991年3月29日调查资料,对该海区自然生态状况和各环境因子的周年变化特征及其各因子之间的相互关系进行了讨论。并对在此期间连续观测时发生的两次夜光藻赤潮全过程中表层和底层溶解氧含量、盐度、水温、叶绿素、pH和营养盐等环境因子的变化与夜光藻密度的关系作了初步的探讨。
On the basis of data from the investigation at sea near Yantian coast, Dapeng Bay,between March 30,1990 and March 29,1991,this article discussed the ecological status,annual variation pattern of environmental factors and the correlation between the factors in the region throughout the year. Change in value of DO in surface layer and nutrients during two occurrences of Noctiluca scientllans were elaborated.
