面对21世纪的中国植物园

在总结中国植物园发展历史及当前国际植物园发展趋势的基础上,论述了中国植物园面对对世纪所必须重视的5个方面。（1）植物园整体质量和特征化,作者列举了10个方面的差距。（2）药用植物的栽培、利用和保护。从药用植物分类学研究,有效成分的分析及动态研究,药用植物栽培化和“地道药材”问题4个方面论述植物园的优势和潜力。阐明了“栽培化”的涵义。（3）引种和物种保护,指出广泛引种的重要性和重点种类迁地保护的必要性,并首次提出了“濒危生境”这个术语及其概念。指出了未来引种理论研究的方向及其对农业生产的意义。（4）活植物收集圃信息系统。（5）科普教育。作者认为,虽然不少植物园目前还面临着或多或少的困难,但就整体而言,未来的10年将是植物园继续较大发展的10年。

论植物园的活植物收集

对植物园活植物收集评价、引种中的取样方法和迁地保护种群大小等问题进行了论述.对活植物收集的评价包括科学性和代表性,最具有科学意义的是经过调查从野外收集的有完整记录的材料,其次是从植物园等机构 引种的有记录的材料,再次是从各地引种的基本上无记录的材料.根据收集物的代表性可分为具有保护意义的收集和保护性收集.取样技术主要针对保护性收集而言,要求收集样本能涵盖该物种95%以上、频率大于5%的等位基因.活植物收集种群的大小应从科学性和现实性二方面来考虑,对植物园里大量的具有保护意义的收集,其种群大小为乔木10～20株,灌木40～50株,草本100～200株;对于保护性收集则至少为乔木50～100株,灌木200株或更多,草本300～500株以上.另外,对当前植物园活植物收集圃建设的一些重要问题也进行了探讨.     

Prospects for Chinese Botanical GardensFoundation items: Supported by Chinese Biodiversity Conservation and Green Development Foundation

In China, a new period of development in the first decade of the 21st Century with rapid urbanization, was marked by investment in construction of over five billion yuan. At this time of rapid change it is important for botanical gardens to follow three principles, “scientific contents, artistic appearance, and cultural display”, so as not to become public parks. The scientific component is important. It is not necessary for every botanical garden to do basic botanical research but they should all be involved in plant conservation issues, especially ex-situ conservation and keep accurate data on their living collections. Although a heavy responsibility this documentation is the foundation and the bottom line of scientific meaning for a botanical garden. Economic plant research, exploring new resources, was a major contribution of botanical gardens historically and remains important for sustainable cities and the national economy of China. Education and ecotourism are important ways for botanical gardens to serve the public displaying the interesting plant collections to enhance relaxation and well-being. It is reasonable to make income through all activities in a botanical garden but this should not be the major goal. It should be understood botanical gardens are comprehensive and multi-functional bodies determined by science, the arts and culture.

The Evolving Role of Botanical Gardens and Natural Areas:A Floristic Case Study from Royal Botanical Gardens,Canada

As leaders calling for the conservation of the world’s plants,botanical gardens protect plants within living collections.Many also study,manage and restore plants in natural habitats.Royal Botanical Gardens(Ontario,Canada) has integrated both horticultural and natural heritage in its mission for decades.Envisioned by municipal leaders in the 1920s as a combination of nature sanctuaries and civic gardens,RBG now includes forests,wetlands and other habitats,gardens and built spaces.Today RBG is Canada’s largest botanical garden on the basis of area.In the 1950s RBG began to inventory plant diversity.The checklist of spontaneous vascular plants now exceeds 1 170 species,of which 752 are native.This is 37% of Ontario’s native vascular plants and 19% of the native vascular flora of Canada.The RBG nature sanctuaries are among the richest locations in Canada for species-level diversity.We examine the history of floristic exploration within RBG and compare plant species-area relationships among protected natural areas in Ontario.This comparison supports the contention that the nature sanctuaries,and in particular Cootes Paradise,could be considered an important area for plants in Canada,and relative to the nation’s flora,a biodiversity hotspot.The fact that a candidate vascular plant hotspot for Canada lies within a major botanical garden presents opportunities for raising public awareness of the importance of plant diversity,as well as focusing attention on the scientific and conservation biology needs of communities and individual species in this area.     

The Evolving Role of Botanical Gardens and Natural Areas: A Floristic Case Study from Royal Botanical Gardens, Canada

As leaders calling for the conservation of the world's plants, botanical gardens protect plants within living collections. Many also study, manage and restore plants in natural habitats. Royal Botanical Gardens (Ontario,Canada) has integrated both horticultural and natural heritage in its mission for decades. Envisioned by municipal leaders in the 1920s as a combination of nature sanctuaries and civic gardens, RBG now includes forests, wetlands and other habitats, gardens and built spaces. Today RBG is Canada's largest botanical garden on the basis of area.In the 1950s RBG began to inventory plant diversity. The checklist of spontaneous vascular plants now exceeds 1 170 species, of which 752 are native. This is 37% of Ontario's native vascular plants and 19% of the native vascular flora of Canada. The RBG nature sanctuaries are among the richest locations in Canada for species-level diversity.We examine the history of fioristic exploration within RBG and compare plant species-area relationships among protected natural areas in Ontario. This comparison supports the contention that the nature sanctuaries, and in particular Cootes Paradise, could be considered an important area for plants in Canada, and relative to the nation's flora, a biodiversity hotspot. The fact that a candidate vascular plant hotspot for Canada lies within a major botanical garden presents opportunities for raising public awareness of the importance of plant diversity, as well as focusing attention on the scientific and conservation biology needs of communities and individual species in this area.
