| 摘 要： | 运用ArcGIS对大理州的主要农业气候资源进行推算，建立小网格推算模型推算温度以及稳定通过界限温度的积温和持续天数，用反距离权重插值方法推算雨量和日照时数。结果表明，基于ArcGIS的大理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: | In the experiment,some main agroclimate resources on Dali Prefecture in Yunnan Province was calculated by ArcGIS software package,and the small grid calculating model was constructed to calculate the temperature and stably accumulated critical temperature and its lasting days,the interpolation method of inverse distance weighted method was used to calculate the rainfall and sunshine hours. The results showed that the calculation of agroclimate resources in Dali Prefecture based on ArcGIS was more precise an... |
