摘　　要：根据1985年4、7和10月的胶州湾水域调查资料,通过对有机农药HCH在胶州湾水域的分布、来源和季节变化的分析,结果表明:HCH含量在整个胶州湾水域都非常低,在这1 a中都<0.150μg/L。通过HCH表、底层含量变化,在时间尺度和空间尺度上证明了作者提出的HCH的水域迁移过程。因此,在4、7和10月,土壤中残留的HCH通过地表径流方式汇入近岸水域,并且HCH的含量很低;HCH来源是面来源,而且来源于陆地。由于HCH的含量很低,水体中HCH含量的季节变化已经没有,10月的HCH表层含量变化范围就是1 a的含量变化范围,已经不受到雨量、地表径流或者河流的影响。胶州湾水域水体中HCH含量的水平分布和垂直分布表明:HCH的含量在胶州湾水域水体中分布都是非常均匀的,揭示了在海洋中的潮汐、海流的作用下,使海洋具有均匀性的特征。Based on the investigation data collected in Jiaozhou bay waters respectively in April,July,and October 1985,the HCH distribution,pollution source,and seasonal variation in the waters are analyzed.It is showed in the study results that in Jiaozhou Bay,HCH contents were very low,less than 0.150 μg/L in the year.Based on the study of the temporal and spatial HCH content variabilies respectively in the surface layer and in the bottom layer,the HCH transport process in the waters,which has been suggested by the authors,is evidenced.The process is that HCH residual in the soils is carried into the coastal waters by runoffs on the land surface in April,July,or October.The HCH content is low and it originates from an areal soarce on land.Because of the low HCH content,no seasonal variation can be found in the waters.The HCH content varies in October within a range which is equivalent to the annual variation range.The HCH content variability is not effected by rainfall or flow volumes of runoffs and rivers.As shown by the vertical and horizontal distributions of HCH content in the waters,the HCH content is homogeneous.It is revealed that due to the effects of marine tides and currents,the waters have their features of the HCH content homogeneity.
