| Notes | 44-1267/S The measured data including accumulated temperature （≥ 10.8℃）, elevation, latitude, longitude, slope and aspect, were selected fi＇om 130 weather station in Yunnan province, and five environmental gradient factors data were extracted from 1： 250000 DEM geographical map of Yunnan province. The muhivariate linear model on accumulated temperature distribution predicting was established based on elevation（x1）, latitude（x2）, longitude（x3）, slope（x4）, aspect index（xs） and accumulated temperature （y） with regress analysis methods and spatial interpolation methods ＇after correlative processing and converting. The results showed that the multivariate linear model was y=28978.223-2.080x1-232.423x2-144.803x3, influencing factors of accumulated temperature were arranged in order of x2,x3,x1. Relevant environmental factors were put into the model to gain flat area accumulated temperature distribution maps with ARCINFO software, and DEM data were rendered to obtain terrain three-dimensional ten＇ain effects chart.
