城市森林的提法最早源于上世纪60年代的美国和加拿大,泛指一般意义上的城市范围内的所有树木。由于城市森林可以直接吸收城市中释放的二氧化碳,同时通过减缓热岛效应,调节城市气候,净化城市空气,还城市一个健康、清洁的环境,所以,以城市森林为规划主题的森林城市建设蓬勃发展,极大推动了生态城市的建设水平。从某种意义上来说,这种以植物为主要自然要素布局的森林城市可以看作是园林城市的形式之一。 The reference to urban forest originated from the United States and Canada in the 1960s, and refers to all trees in the urban area in the general sense. Since urban forests can directly absorb the carbon dioxide released by cities, at the same time, they can regulate the urban climate, purify the city air, and provide a healthy and clean environment for the city by slowing down the heat island effect. Therefore, the construction of forest cities with urban forests as the theme is booming. Greatly promoted the level of ecological city construction. In a sense, this kind of forest city with plants as its main natural elements can be regarded as one of the forms of garden cities.
