| 摘 要： | 以ARCGIS为平台,利用吉林省1∶25万DEM数据,土地利用数据和气象台站资料,在Kriging插值的基础上,综合考虑下垫面、海拔高度、坡度、坡向和坡位等地形要素对风速的影响,对吉林省的冬季风风速分布进行模拟。研究结果表明,基于地形因子的风速校正有效提高了风速插值的精度,可以作为风速插值方法的有效补充,实现复杂地形条件下风速的精确模拟。

| Abstract: | Based on the ARCGIS and Kriging interpolation, use the 1：250000 DEM, the meteorology observa- tion data and land use data simulated the distribution ofwinter monsoon speed in Jilin Province. The Simulation Process which consided the influence of the land use types, altitude, gradient and aspect of the landform was ana- lyzed. The test results show that rectify the result of wind speed interpolation by terrain factor will improve the precision of wind speed interpolation. FullY consider the effect of terrain factor is an effective complement to wind interpolation and actualize the precise simulation of wind speed in complex terrain. |
