摘要 针对某些下垫面复杂而气象站(哨)有限的山区,用地理信息系统(GIS)和气温推算数学模型相结合,来获取全域的年均温分布栅格图和等值线矢量图。以龙游县为例,说明了该方法从数学模型、因素图输入、图层格式转换、图幅叠置分析等一系列技术步骤。 The method of obtaining the precise regional temperature distrbution map is worth studying in the complicated underlying surface region with the lacking of meteorological materials. It can, furthmore,provide the important references for the local agro-production,regionalization of local planning and optimization of agricultural structure etc. A new method of simulating and mapping the annual mean temperature in mountain area was presented with G1S technology and temperature simulation model. Taking Longyou County, Zhejiang Province as an example, a series of technical steps were introduced. Firstly a multiple linear regression equations of T on A (longitude) ,9)(latitude)and h(altitude),with Tg value (macrotopography) ,w.ere obtained from observing data. Then related factors' maps were genered by supporting ARC/INFO software. Through overlaying maps and converting structure of data,the vector and grid of annual mean temperature distrbution maps were drawn. In conclusion, the tested result of Longyou County shows that the method is satified and practical. It is also more convenient and precise in mapping than the conventional ways (i. e. the little grid analysis method).
