中文摘要: 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-<

Abstract:In order to analysis the climate resource and 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 CityStar40 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%
