| 摘 要： | 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Arc-GIS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。

| Abstract: | 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 annum 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 re- sources calculation results based on ArcGIS is more accurate, convenient and extensive use compared with traditional methods. |
