摘要
通过对升金湖实地样方调查,对升金湖水生植物群落现状进行了统计分析.结果发现组成升金湖水生植物群落的主要优势种类有21种,频度分析发现群落中低频度种的数目较高频度种的数目多.升金湖水生植物群落分布格局复杂,种群中各个体分布不均匀,成群、成丛、成块或斑块状地密集分布;各群大小、群间距离、群内个体的密度都不相等;各群大都是不规则随机分布.水生植物分布广,占全湖水域面积48.16%.
The state of community of aquatic plants in Shengjin Lake was analyzed by means of quadrat investigation.The results showed that the community of aquatic plants in Shengjin Lake was composed of 21 dominant species.The frequency analysis indicated that the low frequency species exceed the high ones in number.The distribution pattern of community of aquatic plants in Shengjin Lake has the characteristics of complex and diversity,with the individuals in populations distributed unevenly as groups or bundles or blocks or plaques. The sizes, distances and densities between the communities were different. The communities were also distributed irregularly. 48.16% of the area of Shengjin Lake were covered by aquatic plants.
