摘要
20世纪以来,建设生态结构合理,生态服务功能高效的城市生态系统,推动生态化城市建设,已成为世界城市发展的新潮流。笔者以苏州为研究对象,认为城市建设是一种渐进、有序的系统发育和功能完善过程,一般要跨越生态卫生、生态安全、生态产业、生态景观和生态文化5个阶段。目前,苏州在生态优美城市建设过程中面临一系列问题,其突破路径为:重构人与自然的关系;遵循生态学原理;提倡利用乡土树种资源;多选用长势旺盛、树形优美、成活率高的树种。尊重植物的生长规律,以长效型为主,注重森林景观、生态系统和生物的多样性,合理进行植物配置,以少养护及零养护为目标。
Since 20th century,it has become a new fashion of urban development in the world to build up urban ecological systems that have suitable ecological structures and effective ecological functions in order to promote the construction of ecological cities.Taking Suzhou as the study object,this paper is aimed to prove that as a gradually and sequentially development process of urban systems and performances,urban construction usually involves five stages：Ecological Health,Ecological Safety,Ecological Industry,Ecological Landscape and Ecological Culture.At present,there are a lot of problems in the ecological construction of magnificent Suzhou.To solve those problems,a large amount of work should be accomplished.Complying with the ecological principles,reconstruction of the relationship between human and nature needs to be finished;it ought to be advocated to make good use of rural forestry resources and select more strong and better shaped tree species;following the growth pattern of plants,long life plants is supposed to be chosen as the main species and a proper disposition of plants must be made to realize the diversity of forest landscape,living creature and ecological system;at last,the maintenance cost of ecological construction should be reduced to the largest extent.
