The Monitoring and Early-warning Information of Eupatorium adenophorum Spreng in Sichuan
Abstract: Violet Eupatorium adenophorum Spreng is our country is so destructive of invasive weed already serious harm to our country, animal husbandry and fishery. Therefore, must establish violet bine ze LAN monitoring and forecasting information system prevention and control its spread further spread. Through the use of violet bine ze LAN monitoring and warning information database collected according to the requirement of sichuan province, the distribution of purple stems ze LAN hazards and investigation and data integration, combined with a statistical analysis of the data, discusses the violet bine ze LAN invasion spread in the process of law. This research will provide violet bine ze LAN monitoring warning to provide important basis
Keywords: Eupatorium adenophorum Spreng; monitor; early-warning;Sichuan
