Provide digital specimen information completed by the specimen room of member units, including general specimens and model specimens. Each sample information includes label information and image information. The former includes specimen collector, date and place of collection, habitat and altitude, identification information and specimen storage place (herbarium).
At present, there are 13 herbarium specimens of Chinese Academy of Sciences system on CVH, with 2.85 million pieces of specimen information and1550,000 pieces of specimen images. Records with missing images have been marked on the home page.
There are 6500 online type specimens, including only the type specimens collected in the herbarium of Institute of Botany, Chinese Academy of Sciences, including gymnosperms, Ranunculaceae, Urticaceae, Theaceae, Fagaceae and other groups. All the information has been verified, and the original documents (PDF format) and high-resolution specimen images of the new species are attached.
Distributed specimen information retrieval system: At present, CVH's centralized retrieval of specimen information has the main defects of long update period and high storage pressure. The distributed specimen information query system we are testing has involved five specimen libraries (called CVH branch libraries), and * * * there are more than 1 10,000 pieces of specimen information that can be updated in real time, and its branch libraries are managed by member units through FTP, which effectively exerts the enthusiasm of member units.
2. Chinese Flora Database
Including Flora of China 125, a complete set of 79 volumes (except the first volume), search the text and plate of local records by family name and plant name (scientific name and Chinese name). Recently, the examination and supplement of retrieval documents have made the database reflect the contents of flora more comprehensively and accurately. In addition to the recognized names, you can also find the scientific names of the discussion parts. Number of database records: more than 45,000.
3. Color gallery
There are more than 50,000 color photos of plants uploaded to CVH website, belonging to 5,700 species in 269 families. Many volunteers have taken photos in the wild in recent years, covering wild plants in 34 provinces (autonomous regions and municipalities) in China. In the next stage, a color map recognition expert system will be gradually established to improve the accuracy of photo recognition.
At this time, the user can enter the scientific name or middle name to query the three databases of specimens, flora and color pictures, which are also the main databases of CVH.
4. Other related databases
In order to facilitate users to use specimen information, the website of China Virtual Herbarium also provides a large number of other related (botany) databases, such as specimen collection place names and herbarium data, taxonomists and titles of their research papers, etc. These databases either come from the summary of practical work experience or are directly transferred from authoritative reference books and audited by experts.
1) Chinese higher plant atlas database
Full-text search is editing a full set of five books and two supplements ***7 books. The words and pictures in the book can be found by family names and plant names (scientific names and middle names). Number of database records: 9057.
2) Local flora and its unified query.
Provide 12 sets of local digital documents (PDF files), and query any 1- 12 kinds of flora information through unified association, including the flora of Tibet, Qinling, Liaoning, Guizhou, Zhejiang, Hainan and other provinces (regions/cities) and regions. In the next stage, it is planned to realize the correlation query between Flora of China and local flora. Number of database records: 47 1 12.
3) "Database of Genus Names of Three Local Records"
Provide the position of common names of vascular plants in China in Flora of China, Illustration of Higher Plants in China and Flora of China, including fascicles and page numbers. These three sets of local chronicles (picture books) are the main reference books for studying plants in China at present. Recently, the database has been reviewed, the newly published volume of Flora of China has been added, and hundreds of records have been revised to make the data more accurate and comprehensive. Number of database records: 3504.
4) Plant name and distribution database
Through this database, simple information such as the name and distribution information (to the provincial level) of seed plants in China can be quickly inquired. The data mainly come from Flora of China and the published Flora of China, which can be regarded as a revision of the catalogue of Flora of China. Current database records: 34056.
5) List of type specimens and its original literature database.
The purpose of this database is to collect the model specimens of China native plants and their published original documents. No matter where the type specimens are collected and preserved at home or abroad, no matter when and in what publications, they should be included as much as possible. Each record includes plant name (scientific name, Chinese name), published publications, collection place and habitat of type specimens, age of specimens, collector and collection number, and specimen storage place (herbarium). Most of the materials are in foreign languages. The data in the database comes from various books and periodicals at home and abroad, among which the code of herbarium conforms to the Index of Chinese Herbarium (China Science and Technology Press) 1990 edited by Holmgren, etc. Index and Fu et al. 1993. Abbreviations are HT: Holotype, IT: Isotype, T: Type. Current database record: 30,705.
6) database of plant name authors (nominators)
According to statistics, up to now, there are more than 5,000 plant naming authors in China, among which nearly 3,500 people have named two or more names. This database is based on the data of 3500 people, and each record includes the author's full name and standard abbreviation, work/date of birth/death, professional group, etc. Author China (entry ***9 19) is accompanied by Chinese name and work unit. This database is compiled according to various books and periodicals at home and abroad, among which the spelling standard of names is mainly based on Brummitt &; Powell 1992, author of plant name. The group code is: A: algae; B: moss; C: spore plants; F: fossil plants; M: fungi and lichens; P: ferns; Student: Seed plants. Current database records: 348 1.
7) Overview of Botanical Literature in China (1949- 1990)
Generally speaking, when inquiring about botanical literature in China before 1950s, you can inquire about E.D. Merrill &; E.H.Walker's Bibliography of East Asian Botany (1938) and its supplement (1960), but after the 1990s, various network resources were mostly used for information inquiry. This database filled the gap between 1950s and 1990s, and mainly covered the literature of plant systematics published by Chinese mainland scholars from 1949- 1990, including the author's name, subject and published books and periodicals. The data in this database mainly comes from the Bibliography of Plant Systematics in China (Chen et al., 1993, Guangdong Science and Technology Press). Current database record: 6879.
8) Comparison database of old and new place names in the specimen collection area.
In our country, the names of specimen collection places before the beginning of the twentieth century often change and are no longer used. In this case, it is necessary to consult the old and new maps, refer to the relevant information collected, make a comparison table of old and new place names, and establish a database of old and new place names, including latitude and longitude data of old place names, for specimen query and taxonomic research. Based on the research experience of Chinese plant taxonomists, we summarized more than 2000 records of old and new place names collected from 1 1 provinces (cities). Each old place name includes its old mbth and location (latitude and longitude) as far as possible, and indicates the name, national standard code and latitude and longitude of the place name in the current county-level administrative area. Number of records in the current database: 2048.
9) Database of Chinese Herbarium
The information in this database is basically based on the Book Index of Chinese Herbarium (Fu et al., 1993), which contains more than 300 herbarium in China, and has recently updated the information of dozens of major herbarium. The information of each herbarium includes the name and address of the herbarium, contact person and contact information, collection characteristics and collection purpose, information of main researchers, etc.
5. Guidance materials for plant identification
This part of the database includes interactive retrieval tables (also called electronic retrieval tables) and graphic descriptions of plant morphological terms. , which aims to provide users with one-stop service from plant feature identification and specimen identification, to the comparison of the above specimens and images, to the description of species morphological characteristics and domestic distribution.
1) electronic retrieval table
This is an interactive computer program. Users constantly input the characteristics of specimens or living plants, and those taxa that do not have these characteristics will be excluded until there is only one taxa left. It is a very good identification tool for systematic botany, biological cataloging and protection. This key table provides an electronic way to search more than 270 families of seed plants in China.
2) Family Dictionary Database
The database is transferred from the websites of member companies, and the information comes from the China Dictionary of Seed Plants (Second Edition) edited by Hou Kuanzhao and Wu. * * * Collected 365,438+009 genera of 276 families of seed plants in China, and emphatically described the morphology, geographical distribution, genus and species statistics and main economic uses of seed plants in China. This book is the best-selling botany book in China. The purpose of making its electronic dictionary is to facilitate users to obtain plant diversity information.
3) Database of "Illustration of Morphological Terms for Plant Identification and Description"
Including the morphological term 1 133 of seed plants, covering most terms used in plant identification and description, involving plant organs such as roots, stems, leaves, flowers, inflorescences and fruits. Each entry consists of four parts: Chinese and English terms and their English definitions. The words are standardized and the interpretation is accurate and concise. Most terms are accompanied by one or more exquisite line drawings (*** 1297), which have obvious characteristics and are of great benefit to readers to understand the meaning of terms. The information in this library mainly comes from Harris &; Harris 1994, Terminology of Plant Identification: Graphical Glossary (translated by Wang Yufei et al., 200 1. Science Press).
4) Database of "List of National Key Protected Wild Plants (First and Second Batch)"
The first batch of catalogues was published and implemented in 1999. The second batch of catalogues has not been officially published after several years of discussion, but it has been basically drafted, so it is listed together for users' reference. There are about 1900 species in the two lists (of which orchids account for about 2/3). The database can query the plant name (Chinese name, scientific name), family name, batch and protection level, domestic distribution (to the provincial level), altitude and other information.
6. Popular Science and Spore Plants (Branch Library)
1) Moss branches and fern branches
Both of them are classified into China plant catalogue, flora, noun explanation, plant photos, expert introduction and topic exchange, which are convenient for specialized users to visit.
2) Kopkow
Mainly based on the scientific popularization of plant species diversity development. Among them, the two columns "General Techniques of Herbarium" and "Commonly Used Medicinal Plants" are specially compiled for "China Virtual Herbarium". The former includes the professional techniques commonly used in herbarium, such as specimen collection and suppression, specimen binding, plant identification with key table, plant name knowledge introduction, etc. The latter selected 100 kinds of medicinal plants commonly used in China and added them to the introduction. Each item includes the name, source, original plant morphological characteristics and functional indications. Each plant is also equipped with beautiful color pictures.
In addition, China Virtual Herbarium also has columns such as "Introduction to Website Construction", "Information Feedback" and "Related Websites", which aims to provide users with comprehensive and convenient information services.
