| 摘 要： | 2008年7~8月调查了长湖湖岸带植物多样性和群落多样性的变化,旨在探讨湖岸带植物多样性变化的原因和保护策略。调查结果显示,长湖湖岸带的植物物种丰富多样,共有32科69属81种;湖岸带的植物群落可划分为17个群丛,并出现了由草本群丛向灌木类、乔木类演化的趋势;过度的围网养殖使沿岸水体的水生植物群落类型有减少趋势,很有价值的一些物种睡莲、芡实、水车前、红菱等消失。因此,湖泊管理部门必须下大力气拆除围网,让湖泊休养生息,从次生裸地恢复成健康的湖泊生态系统。

Study on the Plant Diversity of Changhu Lakeshore in Hubei Province |

| Abstract: | From July to August in 2008,the species diversity and community diversity of plants in the lakeside of Changhu Lake were studied.The main objective was to find out the reason for plant diversity change in Changhu Lake and discuss the protective approach.Research results showed that abundant species distributed in the lakeside of Changhu Lake.There were 81 plant species belonging to 69 genera in 32 families.The plant communities in the lakeside of Changhu Lake could be divided into 17 cluster types.The community types would shift from herb associations to shrubby or tree associations.Owning to the man-made disturbances of excessive aquaculture,community types of aquatic macrophytes decreased in the lakeshore of Changhu Lake.The important species Nymphaea,Euryale ferox,Ottelia alismoides,Trapa bicornisa disappeared.Therefore,it was urgent for the lake management department to remove those enclosures so that Changhu Lake could be restored from secondary bare land to healthy ecosystem. |
