| 摘 要： | 通过对全球1961～1990年气象数据的分析与统计,将7 775个站点的气温与降水换算成草地综合顺序分类指标-＞0℃的年积温(Σθ)和湿润度(K)值,在Arc GIS平台上,配以世界行政区划图,依据综合顺序分类理论,制作世界草地综合顺序分类图.研究结果表明:可将世界陆域草地分为38类,基本符合全球气候带以及植被的分布,...

| Abstract: | Based on analysis of meteorological data of 7 775 stations from 1961 to 1990,the temperature and precipitation were converted to >0℃ accumulated temperature(Σθ)and humidity(K).With the world administrative map,global grassland classification map based on the Integrated Orderly Classification System of Grassland was established on Arc GIS platform.The result showed that the global grassland could be divided into 38 classes,which was essentially consistent with the distribution of climatic zones and vegetation.Research method and result are proper. |
