Analysis of digitized specimens of higher plants in China
摘要
Abstract
Traditionally,herbarium specimens are mainly used for plant taxonomy and resource science research.The emergence of digitized specimens has expanded the use of specimens to a wider range of fields,from the study of temporal and spatial distribution of biodiversity to theoretical ecology and evolutionary,biodiversity conservation,agriculture and human health.Up to now,information of more than 12 million plant specimen sheets collected from China has been available on the internet.This paper compiles and analyzes these data to evaluate the digitization accuracy,the temporal and spatial pattern of herbarium collection,and the collection vacancy of Chinese plant specimens,so as to provide a basis for further improving the digitization and accurate collection of plant specimens.The results are as follows:The collection of specimens in China formed four peaks,namely,the 1930s,the 1960s,the 1980s and the early 21st century,and the collection and research of Chinese plant specimens have been mainly completed by Chinese scholars since the 1950s.The coverage of specimen collection is rather high on province level while greatly unbalanced on county level.The coverage of specimen collection by plant groups is high on family and genus level,but nearly one fifth of the species have not been collected sufficiently.The number of collected specimens is related to the distribution range of plants,as well as the popularity of the collection area,the scientific research projects,and the preferences of the collectors.To better digitize Chinese plant specimens in the future,we should continue to explore the undigitized herbarium specimens,review and supplement the existing digitized specimen information,and strengthen the information sharing with European and American herbaria to obtain the information of early historical specimens.The results from our analysis can be applied as a guidance for accurate collection of specimens in China,showing the weak or blank areas and genera/species,which can further enhance the capacity of the herbaria and improve the quality of digitized specimens to better serve science and the society.关键词
