摘要
为了掌握北京市建成区公园植物多样性及近自然群落情况,进而为北京城市绿化提供科学基础,对北京市五环内的公园进行了抽样调查和分析。在靠近市中心的很多公园中,我们发现,应用最多的是乔木+灌木,乔木+草坪或少量乔木+少量灌木+草坪型群落结构,近自然化程度较差。本文指出在城市公园建设中应以自然植被和群落演替的基本理论为依据,选择乡土树种即当地自然植被中的主要乔、灌木种类,"模拟自然"的技术和方法通过人工营造与植被自然生长的完美结合,建造以乔木为主体,乔灌花草多种植物相结合、常绿落叶相结合的近自然群落。
In order to know the situation of plant biodiversity of Beijing urban park and approaching nature plant community and provide the data that were crucial for making a scientific city virescence, sampling surveys on plant biodiversity were conducted. The results showed that in many parks near the city centers, the type of tree ＋ frutex, tree ＋ lawn or little tree ＋ little frutex ＋ lawn community structure were applied mostly. In construction of the city park, we should chose the suitable agrestic plants based on the basic theory of ecology and community succession and use the technique of＂ imitate nature＂ to construct the approaching nature communities in which the trees species were dominated and the shrub and grass were also included.
