中文摘要：

periphytic 硅藻的殖民特征在黄海的沿海的水里被学习，从 5 月的北中国到 2010 年 6 月，使用玻璃作为一个人工的基础滑动。样品一次被收集从 1 和 3 m 的二深度的 1， 3， 7， 10， 14， 21 和 28 d 的间隔。硅藻殖民过程的动力学在社区结构有一个类似的模式并且在两深度在生长曲线适合逻辑模型。为到达 50% 最大的丰富(10 d ) 的最大的丰富和时间没显示出重要差别(P > 0.05 ) 在二深度之间 1 和 3 m。尽管硅藻社区代表了类似的分类作文，他们在结构的参数并且连续的时间的模式不同在二层之间的主导的种类的动力学。显示出的种类丰富更高显著地在殖民时期期间珍视超过 14 d，当种类差异和平均与显著地不同的价值代表了更高的可变性时(P < 0.05 ) 在 1 m 的深度比在更深的层。结果建议硅藻殖民跟随逻辑模型生长曲线并且在沿海的水里在在不同深度之间的殖民特征不同，并且在 1 m 的采样策略是更有效的在海洋的生态系统为 bioassessment 检测生态的特征。

英文摘要：

The colonization features of periphytic diatoms were studied in coastal waters of the Yellow Sea, northern China from May to June 2010, using glass slides as an artificial substratum. Samples were collected at a time interval of 1, 3, 7, 10, 14, 21 and 28 d from two depths of 1 and 3 m. The dynamics of diatom colonization process had a similar pattern in community structure and fitted the logistic model in growth curve at both depths. The maximum abundance and the time for reaching 50% maximum abundance （10 d） showed no significant differences （P〉0.05） between two depths 1 and 3 m. Although the diatom communities repre- sented similar taxonomic composition, they differed in the temporal pattern of structural parameters and in succession dynamics of dominant species between the two layers. The species richness showed significantly higher values during the colonization period more than 14 d, while the species diversity and evenness rep- resented a higher variability with significantly different values （P〈0.05） at a depth of 1 m than at a deeper layer. The results suggest that the diatom colonization follows the logistic model growth curve and differs in colonization features between different depths in the coastal waters, and that the sampling strategy at i m is more effective to detect the ecological features for bioassessment in marine ecosystems.
