南京城区水体水生植物调查

以南京城区典型水体为对象,调查分析了水生植物种类及应用频度,水生植物群落数量、结构及景观特征。结果表明,南京城区已普遍应用的水生植物共96种,分别隶属于47科。其中,湿生植物68种,挺水植物17种,浮叶植物8种,沉水植物3种。水质相对较好的城东和城北地区的水生植物种类较多,群落结构相对较丰富。总体来看,南京城区水生植物应用仍存在种类少、缺乏沉水植物层、景观雷同、竖向及横向景观不足等问题,应在今后的水体景观营建中加以改善。

Investigation of Aquatic Plants in Urban Water Bodies in Nanjing

A survey was performed to study the species and application frequency of aquatic plants,as well as quantitative cha-racteristics,structure and landscape features of aquatic plant communities in typical water bodies in Nanjing City.A total of 96 species of aquatic plants belonging to 47 families are applied widely in Nanjing,which include 68 species of hygrophytes,17 species of emergent plants,8 species of floating-leaved plants,and 3 species of submerged plants.The species and community structure of the aquatic plants in the east and the north of the city are relatively abundant,where the water quality is also relatively better.On the whole,some problems still exist,such as few species,deficiency of submerged plants,duplication of landscape,insufficiency of horizontal and vertical landscape,etc.,which should be improved in water landscape construction in future.
