摘要
提出了一种在气象站点实测数据基础上,利用GIS技术建立山区温度分布模型的方法。通过建立数字地形模型(DTM),获取影响山地温度分布的地形要素,并结合太阳年运动轨迹求出任一地点的天文太阳辐射值,同时考虑海拔高度、地理位置等影响气温的因素以及站点实测数据建立山区温度分布模型。
A method of combining GIS with measured data from meteorology station to establish temperature distribution model in mountain area is introduced. On the basis of DEM, terrain characteristics and solar data for various dates are used to derive insolation.Elevation, latitude and longitude with insolation are used to establish temperature distribution model in mountain area.
