A Prediction System Based On Webgis For Population Ynamics Of Cereal Aphids Under Climate Change

Wheat is one of the China’s major grain crops, cereal aphids is an important pest against the wheatproduction, accurate forecasting in the environment of increased global warming is the key to wheataphid prevention. With the rapid development of information and network technology, traditionalforecasting techniques have been unable to meet the needs of the wheat aphids forecasting, geographicinformation system technology gradually become a powerful tool of prediction. GIS technology andWeb technology combined with the development of WebGIS technology, GIS technology has beenpopular for its intuitive and easy operation accepted by the majority of users.This paper uses a more advanced Arcgis Server platform technology to develop the WebGIS system,object-oriented approach, combined with ASP.NET technology, the use of browser/server architecturelayered design of the system.This study include the following:1. Constructed wheat aphid prediction system based on WebGIS climate change and build moreadvanced technology.2. The visual presentation of meteorological data, pest data WebGIS technology, users can grasp onthe macro.3. System with cereal aphid population forecasting model combines and the cereal aphidpopulation dynamics forecast to achieve the desired effectThe system of spatial data, meteorological data, the cereal aphids basic data organization, display,query and other functions, and combining with wheat aphids prediction models, the cereal aphidspopulation dynamics of the prediction function. The system provides a reference for cereal aphidsforecasting technology, will become an effective tool in plant protection.
