摘    要:水生植物群落特征是水环境质量的重要标志.为了解京杭大运河(杭州段)的水生生态系统中水生植物的分布特点,探析水质与植物群落间的关系,对其5个典型断面水域中的水生植物进行了调查:考察了各断面水域中水生植物物种组成、多样性分布规律、生物量和主要优势种;分析了水环境的温度、pH值、透明度、溶解氧和主要生源要素等理化因子;采用多元统计方法,探讨了浮游植物多样性分布与环境因子的相关性;并对各断面水体的营养水平进行了评价.结果表明,京杭大运河(杭州段)典型断面的水生植物多样性主要取决于浮游植物的多样性,共观察鉴定了35属的藻类,其中优势群落为硅藻门的明盘藻属(Hyalodiscus Ehrenberg)与直链藻属(Melosira Agardh);从对浮游植物多样性及分布的影响来看,在现有的6个环境因子中,溶解氧、透明度、水温理化因子均对浮游植物的分布产生明显影响,而pH值的影响最大;就水质营养化程度而言,塘栖大桥和卖鱼桥相对污染程度较轻,义桥、顾家桥和拱宸桥污染程度较高,而义桥污染最为严重.

关 键 词:京杭大运河  水生植物  浮游植物  多样性  环境因子

Abstract:Community characteristics of aquatic plant are important indicators for water quality. In order to understand the distribution characteristics of aquatic plants in aquatic ecosystem of the Beijing-Hangzhou Grand Canal (Hangzhou section), and to analyze the relationship between water quality and plant community, an investigation of the aquatic plants in five typical sites was made in this study. Species composition, biological diversity, quantity distribution and dominant species of aquatic plants in five sites were studied for ecological changes. Physicochemical factors such as temperature, pH value, transparency, dissolved oxygen and main elements of living were also analyzed. Based on the results, the distribution of phytoplankton diversity and environment factor correlations by multivariate statistical analysis were discussed. The trophic levels of these sites were assessed by using related biological standards. Results indicated that the diversity of aquatic plant mainly depends on the diversity of phytoplankton in the typical sites of the Beijing-Hangzhou Grand Canal. We observed and identified 35 genus algae, including advantage community of Hyalodiscus Ehrenberg and Melosira Agardh, which belonged to Bacillariophyta. According to the impact on the phytoplankton diversity and distribution, factors such as dissolved oxygen, transparency, water temperature, etc. had an obvious influence on the distribution of phytoplankton in the existing 6 environmental factors, while the influence of pH value was the highest. In terms of water quality eutrophication, site Tangxi Bridge and Maiyu Bridge showed a relatively lighter pollution, while site Yiqiao Bridge, Gujia Bridge and Gongchen Bridge showed a higher pollution, and the pollution of site Yiqiao Bridge was the most serious.
Keywords:Beijing-Hangzhou Grand Canal  aquatic plant  phytoplankton  diversity  environmental factors
