运用ArcGIS对川西高原阿坝州的主要农业气候资源光、温、水要素进行推算,建立小网格推算模型推算了年平均气温度、≥0℃和≥10℃积温、≥0℃和≥10℃积温天数、地面年平均温度、年日照时数,用反距离权重插值方法推算年总降水量.结果表明,基于ArcGIS的阿坝州农业气候资源推算结果较传统方法推算的结果更加精细、准确,应用更加广泛、方便.%The main agricultural climate resources of light, temperature, water factor in western Sichuan ABA Plateau were calculated by u-sing ArcGIS, the small grids reckoning model was established for calculating the average annual air temperature, accumulated temperature a-bove 0℃ and 10 ℃ , accumulated temperature above 0 ℃ and 10 ℃ days, annual average temperature, annual daily sunshine hours, inverse distance weighted interpolation method was used for calculating annual total precipitation. The results showed that, the agricultural climate resources calculation results based on ArcGIS is more accurate, convenient and extensive use compared with traditional methods.
