| 摘 要： | 这是一个借鉴日本经验,结合上海实际的小试。选择了上海11个乡土树种,面积为3000m2,经过3年的生长,最大植株高度达4.6m,已经初步展现景观效果,预计10~20年可形成近自然森林。

| Abstract: | "Close-to-nature" is a new technology in the field of restoration of urban vegetation. It is based on the theories of potential natural vegetation and succession. Containerized seedlings of native species are used with similar species composition to natural forest. The development of close to nature forests is considered faster than the succession process of natural forest in the same region. Compared with green space in the city, they have some notable features such as low construction cost and less maintenance in later stage, complete community structure, high species diversity and biomass and relatively steady state etc. A model stand of close- to- nature forest with an area of 3000 m2 was established as a case study in Pudong New Area in 2000. Threeyears after planting, the shrubbery physiognomy has been formed, and the tallest tree reached 4.6 m in height. A forest physiognomy is estimated to form in around 10 years. The method of building close to nature forest has been used all over the world. It will also play a key role in the building urban forest in China. |
