摘要
中国植物区系地理学在植物区系的调查、分布区类型的划分和研究、植物区系分区以及区域植物区系的分析等方面有了丰富的研究积累。但这些研究绝大部分是利用传统方法对植物物种或分类群数据进行统计分析,因此仍处于对区系现象的认识和描述阶段,缺乏空间格局形成过程、形成机制方面的深入探索。此外,还存在植物区系调查薄弱甚至是空白的地区,许多植物标本缺乏详细或精确的信息,植物物种鉴定的准确性还需要提高。同时,随着植物区系地理以及相关学科的快速发展,植物区系地理学的研究步入了多学科交叉融合、综合研究分析的阶段,学科界限趋于模糊。一方面,利用物种信息数据库,融合生态学、古植物学以及地质历史等探讨区系空间地理格局的成因;另一方面,结合系统发育、分子系统进化(甚至到进化基因组学)、生命之树以及分子生物地理学等揭示区系的起源和进化;同时,各学科的快速发展,产生了大量的数据,新的分析方法或新理论的出现和运用,使植物区系地理研究也进入到了大数据时代,进而使得植物区系地理研究由定性的现象认识和描述,逐步深入到了定量地解释区系现象和探索其形成机制的时代。
This paper summarizes the research status, existing issues, and trends in floristic geography. There is now a wealth of research accumulation on floristic investigations, distribution types of genera, floristic re- gions, and regional floristic analysis. It is also noted that most of these studies utilize simple statistical analy- ses, comparative studies, traditional methods, and single subjects, to provide a basic understanding and de- scription of the floristic phenomenon, which is lacking spatial pattern formation processes and detailed ex- ploration of formation mechanisms. Additionally, there are still some weak and non-existent areas of botani- cal investigation. Many existing specimens lack detailed or accurate information and the precise identifica- tion of plant species also needs to be much improved. At the same time, when analyzing the development trends of floristic geography, with the rapid development of related disciplines, including the development of biogeography and analysis methods and improvements, floristic geography research is an area of multidisci- plinary integration, comprehensive research, and analysis. On the one hand, using database information, and combining ecology, paleobotany, and geology can allow us to probe into spatial pattern formation. On the other hand, combining phylogenetics, the tree of life, and molecular biogeography allow us to reveal floristic origins and evolution. The rapid development of various disciplines has given rise to a large amount of data, meanwhile, the emergence and application of new analytical methods and theories incorporate big data into floristic geography research, which will enhance qualitative understanding and description, and allow us to further explore the mechanisms of formation quantitatively.
