Simulation of Facility Agricultural Climate Resources Based on GIS in Sichuan Province

By using the data of climate observation and site geographical information collected from 134 meteorological stations in Sichuan province since 1971, this paper established a calculation model in small grid to calculate the climate resources of facility agriculture including the days, precipitation and effective accumulated temperature in suitable period in Sichuan province. Based on Geographic Information System (GIS), the model was calculated and used to verify residual modification so as to ensure the relative accuracy of calculated values. Meanwhile, the plane and stereoscopic distribution maps of facility agricultural climate resources were made to lay foundation for further division work in Sichuan.
