摘要

河口地区是海陆相互作用的主要场所之一,这一区域的水文状况既不属于典型的陆相,也不属于典型的海相,而是由河口排入的大量淡水与海水混合而成。这一区域的水文状况比较复杂,海水中含有丰富的营养盐及矿物质,是海洋生物繁殖、栖居的良好环境，也是人类开发利用海洋的极好场所。因而研究河口区域理化环境的分布变化对了解河水海水界面的转移规律和河口区生态学的研究都具有重要的意义。黄河是世界泥沙浓度最高的河流,年平均入海泥沙的浓度为24.5kg/m3,在每年约11亿吨的泥沙中,有3亿多吨进入开阔海域。由于多年的淤积沉淀,岸边海水不断变浅,冲积平原区域面积亦不断增加,故而使黄河入海处的河道经常改道,其河口处的水文状况也有所变化,因此经常对黄河口海域进行调查和研究是很有必要的。本文利用1989年8月对黄河口及其附近海域综合调查的资料讨论了黄河口区域的水文、水化及生物分布特征,并应用Fuzzy 聚类法对该海区夏季的海水类型进行了综合性的分析。这对了解和研究该海域的初级生产力、河水与海水混合过程中的环境因子与生物之间的关系,以及石油开发、海水捕捞、水产增养殖等都具有重要意义。

Abstract

The characteristics of the distribution and variations of ten natual environment factors are discussed in thispaper, based on the data from comprehensive Investigations in the Yellow River estuary and its nearby coastal zone in August 1989.Seawater type in these areas were divided by means of the fuzzy cluster method.The results show that there are three seawater types in the Yellow River estuary and its nearby coastal zone in summer: the Bohai coastal seawater, the Yellow River estuary mixed seawater, and the coastal diluted seawater.
