ON THE DEVELOPMENT OF CHINA WEED INFORMATION SYSTEM BASED ON THE WEB

摘要

China Weed Information System (CWIS), a web based information system about weed sciences in China is developed using modern computer and network technologies. It could be used to obtain large amount of information on weed species and its management. In SQL Server, several databases were created, such as databases of weed species and specimens, herbicides, quarantine weeds and reference materials. By ASP pages and ODBC, these databases were connected to the query interface of web pages and the weed information could be shared online with weed researchers all over the world. In CWIS, information of 2270 weed species belonging to 144 families, 823 genus in China were stored, which included their name, prevalence, damage, distribution, morphological description, photos, control methods, specimens etc. You could query the information of those weed species by Chinese name, English name, Latin binomial or their biological characteristics, or you could use multiple parameters to narrow the search results. These data could be obtained rapidly and conveniently. In addition, you could make statistical analysis of weeds in China based on these databases. The decision-making features of the CWIS allow you to select herbicides or other measures to implement your weed control strategy. In CWIS you also could get the reference materials, identify the weed species and manage the information of weed specimens.
