| Abstract: | Development of WebGIS-based warning information system of planthoppers disaster is a significant work in rice insect pest control. Based on the principle of WebGIS database, ArcGIS8. 1 was used to design and develop warning system for planthoppers in Guangdong Province, which was also used as a analytical platform to predict the spatial-temperal fluctuation of planthopper population. The principle of WebGIS, technical supporting standard, systematical structure and methods of creating database and spatial analyzing modes were described in details. A database including spatial and corresponding attribute sub-database was constructed based an history records. The warning system will provide great assistance for pest managers in spatio-temporal analysis, besides its basic database management functions such as data inputting, outputting, editing and querying. An example of WebGIS-based system was presented for planthopper management in Guangdong Provincial. |
