城市集人类物质文明和精神文明之大成,是经济、政治、科技和文化的中心。目前,全球有50%左右的人口居住在城市,创造了世界70%以上的产值。与此同时,城市的发展也付出了沉重的环境代价。当今世界,寻求自然化、生态化已经成为城市建设的大趋势,建设城市森林、促进人与自然和谐,代表着城市发展的新潮流。我国在城市森林建设方面起步不算太晚,在“建设和谐社会”中面临难得的机遇。
City set the culmination of human material and spiritual civilization, is the economic, political, technological and cultural center. Currently, about 50% of the world’s population live in cities, creating more than 70% of the world’s output. At the same time, the development of the city has also paid a heavy environmental price. In today’s world, the search for naturalization and ecologization have become the general trend of urban construction. The construction of urban forest and the promotion of harmony between man and nature represent the new trend of urban development. It is not too late for our country to start the urban forest construction and it faces a rare opportunity in “building a harmonious society.”
