导言城市自然地理学的研究在气候学、地貌学和水文学方面已经有很大进展。但是,地理学家对于城市生物区系的研究尚未给予应有的注意。极其丰富多彩的城市植物区系,它与同样是变化多端的生境的联系,以及——更重要地——城市植物区系显著的空间变化,为地理探索提供了有价值的、富于创造性的课题。世界许多地区日益城市化的人类种群以及随之而来的与自然界的隔离,要求在城市区域加强生物学研究。人与环境的相互作用这一地理学的基本课题,在城市植被中鲜明地体现出来。
Introduction The study of urban physical geography has made great progress in climatology, geomorphology and hydrology. However, geographers have not paid due attention to the study of urban biota. An extremely rich and colorful urban flora, which is linked to equally diverse habitats, and—more importantly—significant spatial changes in the flora of the city provide valuable and creative means for geographical exploration. Question. The increasing urbanization of human populations in many parts of the world and the consequent isolation from the natural world requires the strengthening of biological research in urban areas. The basic subject of geography, the interaction between man and the environment, is clearly reflected in urban vegetation.
