摘要
奥林匹克森林公园是目前北京市最大的城市公园,自建成以来,奥林匹克森林公园的植物种类组成与来源尚无报道。论文在实地调查数据的基础上,对北京市奥林匹克森林公园的植物组成与分布进行了研究,调查发现园内共有维管束植物295种,隶属于75科,203属,其中乔木种60种,灌木种57种,草本植物170种,藤本8种。按照植物种的自然分布情况统计,发现在园内295种维管束植物中,有北京地区乡土种179种,外来种116种,其中包括外来入侵种4种。按照植物种的来源统计,发现有人工栽种种183种,野生种112种。通过比较分析:发现公园内栽培的本地灌木种占全部栽培灌木种数比例(50.00%)高于整个北京市建成区的比例(27.00%);公园内物种多是国内引进。最后提出了丰富园内野生灌木植物种类;保持乡土种利用;减少对外来种使用等的建议。
The Beijing Olympic Forest Park is the largest city park in Beijing.Since the Olympic Forest Park was built,the plant species composition and sources have not been reported.We researched the composition and distribution of plants in the Beijing Olympic Forest Park based on the field survey data.We found that the park has the vascular plant of 295 species belonging to 75 families,203 genera,including 60 species of arbor,57 species of shrubs,170 species of herbs and 8 species of vines.It has 179 local species and 116 exotic species,including four invasive species in all plant species.It has 183 cultivated plants species,and 112 wild plant species.In the park,the proportion of cultivation of local shrubs species(50.00%) is higher than in the built-up areas of Beijing(27.00%),and there are more domestic introduction species.Finally we put forward some suggestions on increasing plant species,keeping local kind of use,and reducing foreign species.
