摘要:
植物多样性是一个地区最重要的自然遗产之一,是人类生存和发展不可缺少的依靠,认识并理解这一自然遗产,并在经济发展中特别加以保护,是不可推卸的责任。北京是举世公认的文化名都,它的众多的文化古迹有大量文献加以记述和评论,但其独特的自然遗产,一直未受到应有的注意。从物种和群落两个层次论述了北京地区植物多样性的组成和特点,并指出过渡性的气候及复杂的地质地貌条件,也就是它的地多样性(geodiversity)是形成其复杂的植物多样性的基础,最后对北京地区植物多样性当前面临的威胁及其缓解办法,提出建议。
Abstract:

Plant diversity is one of the most important natural heritages of a region, and is an indispensable condition for existence and development of humankind. Recognizing and understanding this natural heritage as well as conserving it is our responsibility which should not be evaded. Beijing is a world known cultural capital and its numerous cultural historical monuments have been recorded and evaluated, yet its distinctive natural heritages have not yet been paid attention to. This paper focuses on the levels of plant species and communities of Beijing region, dealing with their composition and characteristics, indicating that transitional climate and complex geological and geomorphological conditions (that is its geodiversity) are the foundations of its plant diversity. Lastly, threats the Beijing plant diversity is confronted with at present time and their alleviating methods are indicated.
