| 摘要: |
| 胶州湾位于山东半岛东南方,东经120°4'24" ，120°22'24" 与北纬35°58'30",36°14'20"之间。海湾北部广阔，南部尖狭，略呈葫芦状。其东西最宽处约29公里，南北最长处约33公里。湾口宽3.15公里，总面积(不包括岛屿)约255平方公里。
胶州湾四周有海泊河、李村河、白沙河、石桥河、红江河、杨河和大沽河等径流流入湾内。这些河流平时流量不大，但每至雨季则水位骤增，直接引起海水盐度等一系列因子的变化。此外，环境污染也在一定程度上影响了海水的理化性质和沿岸海洋生物的栖息分布。 |

| Abstract: |
| Jiaozhou Bay is situated at the south side of the Shandong peninsula, between long. 120°5'30"-120°24'30"E and lat. 35°58'30"-36°14'20"N. It is about 29 kilometers wide and about 33 kilometers long, with a total area of about 255 square kilometers. Its water temperature at surface is rather varied, the February monthly mean is about 2℃, while that for August is about 25℃. The salinity of sea water varies monthly, the highest average monthly salinity being 31.24‰ in June and the lowest being 29.61‰ in August. The types of tides are regular semi-diurnal, with a tidal range of not over 4.7 m usually.
The universal intertidal zonation by Lewis was used for Jiaozhou Bay, in which the belt from upper limit of Littorina to upper limit of barnacles is called littoral fringe, whereas that from upper limit of barnacles to upper limit of Laminaria is called eulittoral.
In order to see how far the subjectively recognized zones represent an overall organism structure, we carried out a hierarchic distance analysis. The analysis was an example of a divisive shortest distance classification and information theory, in which frequency and cover data for individual species were used as the basis for both classification and amount of information. From the species pair association matrices, we constructed a hierarchical dendrogram to indicate the occurrence of some major subgroups. |
