Pest-GIS For Pest's Compiling And Forecast And Its Primary Application On The Migration Of Wheat Aphid

Agricultural pest ususlly break out in our nation and our ability of control them is very weakness. So the harm being done by agricultural pest became the key obstacle to agriculture development. To control and forecast the pest effectively in China, and enforce our resistance and management the pest of invasion species, I build up IPMGIS. It can interpolate the climate data when they have been queried and analyzed through different orientations and dimensions. Then it makes special subject map. Base on the analysis of the climate database, by the aid of the mathematic ecology model in existence, the system can forecast the range, generations of pest and so on and evaluate the risk of important quarantine pest. Through compilation the database of national universal investigate on pest insects and plant diseases from year 2001 to 2002, we can get nearly all the information of the pest include their range and degree. On the ground of this system, with the super-cooling-point of wheat aphids I measured I validate the reality and direction of their imgration after I analysis the temperature datum and orient of wind in the climate database.
