摘要
文章通过对上海市区内比较有代表性的三座公园绿地:延中绿地、世纪公园和上海植物园的植物群落组成的区系成份的分析对城市绿地公园人工植物群落的"近自然性"进行了尝试性的研究,并运用经典的相似性系数法对结果进行了评估。结果显示,世纪公园的群落组成最接近自然群落,上海植物园次之,延中绿地最差。总体来讲,上海城市公园绿地对于乡土植物的保护和利用尚有待提高。
＂Closeness-to-nature＂ is an advanced garden planning idea, and also a common requirement of citizens for urban park green space. Three park green spaces were selected, i.e. Yanzhong Lawn, Century Park, and Shanghai Botanical Garden, to analyze the floristic composition of the plant communities. Based on the analysis, the closeness- to-natural of artificial plant community of urban park green space was tentatively investigated, and then the classical similarity coefficient method was employed to evaluate the investigation results. The result showed that Century Park had the community composition closest to natural community, followed by Shanghai Botanical Garden and Yanzhong Lawn. Generally speaking, Shanghai should put more effort into the conservation and utilization of indigenous plants in urban park green space.
