摘要:
江苏省淮安市地处中国南北交接带,其地域植被位于温带落叶阔叶林和亚热带常绿阔叶林分界处,分布具有比较典型的南北差异特征。为了研究城市河流水陆交错带生态功能,对贯穿主城区的4条河流的滨河绿地展开植物群落调查,并对植物物种组成进行分析。结果表明,各样地的乔木物种Pielou均匀度指数较为一致,但 Simpson指数、Shannon-Wiener指数有所不同,根据大小排序,样地依次为里运河>盐河>古黄河>大运河;各样地灌木物种Simpson指数、Shannon-Wiener指数和Pielou均匀度指数的大小依次排序为里运河>盐河>古黄河>大运河。从数量特征和生物多样性的情况来看,综合平均指标东段2岸比西段2岸高,此结果验证了规划要求近20 a内城市中心东移的趋势。含有植物种类较多的科主要依次为蔷薇科、豆科、木犀科、柏科和木兰科。乡土植物芦苇、杨树、柳树、女贞等在大面积的绿化中使用率较高,且效果很好。但总体上看,常绿树种数少于落叶树种数,可能是造成寒冷季节景观不佳的主要原因。
Abstract:
Huai’an in Jiangsu Province is located in the North-South junction, and vegetation distribution has a typical characteristics of North-South differences in the eastern region of China. In order to study the ecological habits of urban waterfront green space, the community survey over four rivers which go through the main urban area was carried out. Through field investigation, the plant species compositions of waterfront greenbelt in Huai’an were resulted. And the obtained data were analyzed by the method of phytocoenosium research and SPSS system. The results showed that the plant community characteristics of river sections coincided with the trend of the city centre having moved eastward. And, major plant species were successively from Rosaceae, Leguminosae, Oleaceae, Cupressaceae and Magnoliaceae. Indigenous tree species such as willows, reeds, privets were mainly grown in a large-scale area of green land, which had a significant effect on the environment around rivers. However, the number of evergreen tree species was less than that of deciduous tree species, which led to bleak landscape in winter season.
