Abstract:

This article uses GIS (Geographical Information System) technology and subcounty (city,district) area as the basic unit,to study on practical rice production situation in Hubei Province in recent years.With comprehensive meteorological data,terrain data,laws of rice crop growth and development,and rice adaptation to climate indicators,the suitability of rice planting area was divided in Hubei Province maps.According to the actual data of rice production in the counties (cities,districts) region,the different types of rice production in high,medium and lowyield areas were designated with a rice planning subcategory of the early,middle and late rice.Through calculation,the rice production potential of light and temperature 17 000-22 000 kg/hm2,the production potential available degree of light and temperature was 3306%-7830%,and the maps of rice planting appropriateness in Hubei Province were established.By using the principle of similarity principle of agroclimatic resources and consistency of agroclimatic,the integrated rice production potential in Hubei Province was 3 174 200.Present study result and the established database can provide the better planning guide and references to cultivation and production of rice,and the implementation of hightechnology project series in Hubei Province.This research method can be extended for the food crop planting zoning and agricultural regionalization
