摘要
借鉴国内外利用DEM计算复杂地形下太阳辐射的模式,开发了一种运用ArcGIS 10.0支持的Add-In插件开发模式,计算复杂地形下太阳辐射的新的工具。利用该工具计算了黑河上游山区2011年全年的日太阳辐射值,并与ArcGIS本身的太阳辐射计算工具运算结果以及位于黑河上游葫芦沟流域的3个气象站点2011年的太阳辐射实测数据进行了比较分析。结果表明,该工具可很好地模拟太阳辐射的时空变异,且运算结果明显优于ArcGIS本身的太阳辐射计算工具。
This study developed a new tool that could calculate the net solar radiation in complex terrains using a new plug-in module supported by ArcGIS10.0 named Add-In. In this paper, we calculated daily net solar radiations of 2011 using the tool, and compared the results with those measured from weather stations in the Hulugou watershed, which was located in the upper reach of the Heihe River Watershed, Northwest China. The comparisons show that the tool can simulate the distribution and variations of solar radiations well. The results indicate that our tool can accurately determine the effects ofterrain on solar radiation estimates and the results are better than that of ArcGIS.
