新形势下中国城镇绿化展望——为实现城镇绿化物种多样性和可持续发展,应加强树种规划与苗圃建设

Biodiversity maintenance and sustainable development for greening cities and towns require appropriate planning of landscape woody plants and sufficient nursery construction.

城镇树种规划是全面选择并安排绿化树种的总体方案,它关系到该地园林成败的大计,必须认真对待.建国后,以国家城市建设总局和中国园林学会等为主,曾领导并讨论过这一重要工作,但只做了一些城市的树种调查与规划,却未作为一个方向性的大事认真全面贯彻.当今大力提倡生物多样性维护和园林建设可持续发展,于是严格制定、全面贯彻并强化树种规划和苗圃建设之必要性愈显突出.文中对有关问题和已经进行的工作进行了回顾,并对今后展开全面树种规划、加强苗圃建设,提出了工作原则、注意事项与展望.

Planning of landscape woody plants for cities and towns is a whole-set arrangement for selected woody species. It is of vital importance to success of greening for a city or a town. In China, as early as 1959, Prof. Wu Zhonglun put forward and discussed this problem. But the work of tree planning has not been carried out in the whole country and not been upheld continuously. At nowadays, biodiversity maintenance and sustainable development are considered very important in urban greening. Therefore we have to strengthen such important work as planning of landscape woody plants and nursery construction, because these works are prerequisites and guaranties of urban greening.
