摘　　要：为便于气候资源分析和农作物、果树等农业气候区划,在分辨率为3″×3″栅格图上的每一点都对应相应的气候要素值,利用泰安市及周围19个气象台站1971—2000年的气象资料,采用三维二次趋势面分析与空间插值相结合等方法,在地理信息系统CityStar4·0平台上对泰安市年平均气温、积温等热量资源进行栅格化。结果显示,各项指标通过检验,复相关系数均在0·960以上,F检验值均大于F0·05。年平均气温、1月平均气温和7月平均气温的平均绝对误差均在0·5℃以内;日平均气温T-日≥0℃、T-日≥5℃、T-日≥10℃、T-日≥15℃的积温的相对误差均在5%以下。In order to analysis the climate resource anu agricultural climatic region, each spot has its corresponding climate value in the grid map of 3＂× 3＂ resolution. The meteorological data of 19 meteorological stations during last 30 years （1971—2000） of Tai＇ an city were used. Under the geographic information system CityStar4.0 platform supporting, the method of two trends-surface of three-dimension analysis and combining with inserting value of space were adopted. The grid maps of resolution 3＂× 3＂ of Tai＇an were produced. The result showed that, each target through the examination, the correlation coefficient are all above 0.960, the examining value of F are greater than F0.05, average absolute errors of the annual mean temperature, the coldest monthly average temperature and the hottest monthly average temperature are less than 0. 5℃, relative error of the accumulated temperature of ≥0℃,≥5℃, ≥10℃ and ≥15℃ are under 5%.
