Paper Abstract

By researching and analyzing the crop diseases and insect pests, we find the distribution and spread of crop diseases and insect pests have tight touch with the time and space information, which provides a premise of applying geography information system (GIS) and spatial interpolation technology especially. By considering the particularity of spatial interpolation on the plant diseases and insect pests in agriculture, the authors bring forward one new method: multifactors spatial interpolation model. It is made up of many factors, such as spatial orientation relationship, topological relationship, distance relationship and national weather conditions so on. Then, on the basis of building the multi-factors spatial interpolation model, the monitor and warning system of crop diseases and insect pests is constructed by using GIS technology and ArcIMS software. The basic functions, such as map visualization, information query, data input, data management, spatial interpolation, are implemented. What's more, by using the multi-factors spatial interpolation model, the effluence and spread speed of crop diseases and insect pests are showed and the monitoring and early-warning of crop diseases and insect pests is implemented.
