| Abstract: | Based on climatological backgrounds and freatures of topography and landscape in Shaanxi province,regionally, the caculating grid model of climatic elements was eatablished,and the climatological resources can be computed to surface grid units. According to index of crop climatological zoning and different weighted standard of every zoning factor,multiplespatial elements were analysed,the space data set of crop agri climatic zoning was obtained. The renovation and vector treatment was made for resource space data of producing, lastly, vector chart of climatic resources and crop agri climatic zoning was shown on. |
