| 摘 要： | 针对太阳辐射在不同区域及地形地貌条件下的差异,借鉴国内外太阳辐射最新研究成果,考虑地形和大气衰减因子及各种可能的影响因子,基于数字高程模型提取坡度、坡向以及地形遮蔽因子,建立了山西高原太阳潜在总辐射计算模型,进而利用纵跨山西南北的3个辐射观测站的5年逐日太阳总辐射晴空观测资料对模型计算结果进行了检验分析,检验结果表明模型适用可行.利用该模型计算分析了山西高原太阳潜在总辐射的时空变化以及地形因子影响下的变化特征,可望为区域小气候变化以及区域植被、农作物所应用的小气候指标提供重要的基础条件.

| Abstract: | Considering different solar radiation between various areas and terrain, and attenuation by terrain, atmosphere and other factors, along with the newly research trends, based on slope, aspect and shadow derived by DEM, a model of potential solar radiation in Shanxi Plateau is established. By comparing with the daily solar radiation observed in three observation stations in 5 years, the results show that the model is feasible. The model was used to analyze the spatial and temporal distributions and variation... |
