摘要
空间插值是各种地学、生态学研究中经常遇到的问题。文章以中国1950年至1998年160个测站年均降水量数据为例,介绍采用空间插值绘图软件Win-Surfer绘制等值线图的基本方法与步骤,并对软件中几种常用的空间插值方法的优缺点进行简要的对比分析。
Spatial interpolation is often applied in geographical and ecological research. The annual average of precipitation data (1950~1998) of 160 base stations in China was taken as a case to introduce the method and steps how to plot isoline with Win-Surfer software. At the some time, several common spatial interpolation were also explained and contrasted briefly.
