摘要:

澄清植物种类是植物分类学研究的基础,也是开展iFlora编研的前提,而植物物种调查则为其提供了最为基础和重要的研究素材。传统的植物物种调查,或以植物区系调查为目的,或是专类植物资源搜集,往往较为忽视种群层面的调查。iFlora计划中,基于地方种群的植物物种调查应予以重视和贯彻实施。系统的植物物种调查将以“个体(标本)—(地方繁育)种群—物种”为核心展开,其中地方繁育种群是调查的中心环节。调查内容将兼顾种群的形态学、生态学和遗传学三方面的学科需求,以期获得全面详实的物种数据,并藉此建立一套完整规范的物种“档案”。在整个植物物种调查中,“模式产地种群”是关注的重点,需制定缜密的调查方案并优先实施。由于模式标本的残缺、原始描述的简略,在未来的物种分类研究中,植物分类学者必须认真考虑“产地模式标本”和“模式产地种群”所扮演的重要角色。作为自然界中客观存在的群体,“模式产地种群”不仅仅是模式标本的注脚和补充,它犹如地质学上的“金钉子”,将为研究者提供最为权威和充分的形态学、生态学和遗传学等研究信息,从而真正将物种分类研究从“故纸堆”的困境中解放出来。

Abstract:

Clarifying plant species is the base of plant taxonomical research and also the premise of iFlora, for which investigations on plant species provide the most basal and important research materials. However, field investigations traditionally are for the flora of some regions or for collecting some kinds of plant resources, but for the local populations of species. Investigation and research of plant species on population level therefore need to be concerned and implemented in the plan of iFlora, in which “individual (specimens)(local breeding) populationplant species” will be the core clue. Different from the past, the field investigation will be targeted at local breeding population and collects morphological, ecological and genetical information as direct proof applied to taxonomical discussion and foundiation of species′ database. Furthermore we should place great importance on populations of type loaclity. Due to fragmentary type specimens and simple original descriptions, researchers have to actively consider “topotype” and “population of type locality” as the extension of “type”. Populations of type locality, which are like as “Golden Spikes” of geology, are more than just footnotes of type specimens, but provide authoritative and abundant information sources for the taxonomical research of plant species.

Key words:  Plant Species, iFlora, Local Breeding Population, Topotype, Population of Type Locality
