摘要:

对洪德元先生最近在《生物多样性》(2016年第24卷第3期)发表的《关于提高物种划分合理性的意见》一文中的部分观点进行了进一步阐述。强调我国植物确实还存在大量种级水平的分类学问题有待解决, 我国植物分类学研究在一些重要发展阶段(如系统阶段和物种生物学阶段)上存在明显缺失, 需要弥补。指出分类学发展到今天, 不宜再强调“经典分类学”和“实验分类学”之分, 应采用多学科手段解决分类学问题; 我国应加强植物分类专著水平的研究工作, 注意培养年轻一辈植物分类学专著工作者; 在分类处理中应用居群概念和统计学方法时应特别谨慎; 在系统植物学中接受物种概念的多元性是必要的, 但要向达到广义的生物学种概念努力, 不宜以有所谓的“归并派”和“细分派”之分为借口而完全主观地划分物种。

关键词: 多学科手段, 物种划分, 种级水平分类学

Abstract

Very recently, Professor Deyuan Hong, the editor-in-chief of the ongoing Flora of Pan-Himalaya, put forward a series of proposals (which may be conveniently termed Hong’s Ten Points) on raising rationality in species delimitation, a hotly-debated question in systematic biology [Hong DY (2016) Opinion on raising rationality in species delimitation. Biodiversity Science, 24: 360-361]. The present paper is mainly to expound on some of the points. Even after the Flora Reipublicae Popularis Sinicae and its English version, Flora of China, was published, many species-level taxonomic problems of plants from China still remain to be solved. This situation may be due in part to previous unsatisfactory taxonomic practice and in part to our poor knowledge of taxonomic characters of a large number of plant groups from the country. Indeed, a very important stage in plant taxonomy, the biosystematic phase, was basically missing in China, and even the consolidation or systematic phase (one of the stages in alpha-taxonomy) has not yet been accomplished for some groups. Nowadays, it is inappropriate to emphasize the separation of orthodox and experimental taxonomy, and a multidisciplinary approach needs to be adopted in addressing taxonomic problems. To gain a fuller understanding of plant biodiversity in China, creative monographic work is badly needed, which requires the training of young botanical monographers. Moreover, it is suggested that practicing taxonomists should take extreme caution when employing population concept and statistical methods in their routine work. Finally, it is argued that every effort should be made toward a broader biological species concept although botanists have to accept the pluralism in species concept. To revert to a purely subjective species concept, under the pretext of the existence of the so-called lumpers or splitters in systematic biology, is not correct and must be opposed.

Key words: multidisciplinary approach, species delimitation, species-level taxonomy
