佛山市区城市绿地植物物种多样性研究

通过对佛山市区所有独立城市绿地中的植物物种调查表明,佛山市区城市绿化中应用了338种(包括变种、栽培种)植物,隶属215属86科;其中乔木177种,隶属111属47科;乔木种类最多的5个科是桑科、棕榈科、桃金娘科、苏木科和蝶形花科。不同行政区域的城市绿地,其植物物种多样性差异很大,城区绿地植物物种多样性明显高于石湾区。不同类型的绿地,植物物种的多样性差别也十分显著,公共绿地的多样性高于其它绿地类型。绿地应用的乔木主要为常绿阔叶树种、乡土树种或慢生树种。绿地中普遍应用的植物或乔木仅30种左右,大部分绿地的植物物种多样性差。本文还对佛山市区城市绿地植物物种多样性、乔木的多样性、多样性建设与保护以及景观优化进行了讨论。

Study on plant species diversity on green space in Foshan urban district

338 species of plants have been used on the green space of Foshan urban district,including varieties and cultivars,which are subdivided into 215 genera and 86 families.And there were 177 species of trees among them,which are subdivided into 111 genera and 47 families.The 5 families of most trees were Moraceae;Palmaceae;Myrtaeae;Caesalpininaeae and Papilionaceae.There was significant difference in plant species diversity of different districts of urban green space.The plant species diversity in Chancheng district was greater than that of Shiwan district.There were also obvious differences in plant species diversity among different types of green space.The plant species diversity on open green space was greater than that of other types.The major trees used on urban green space were evergreen trees,native trees or slowly growing trees.The trees used commonly on Foshan urban green space were 30 species of plants or trees.The plant species diversity of main urban green space was bad.How do we build and protect plant species and tree diversity on urban green space are also discussed in this paper.
