中文摘要	草原是畜牧业生产的根本,科学合理的分类是草原开发利用、培育保护和经营管理的基础.本研究根据甘南及周边地区55个气象台站30年的气象资料,采用地统计学及回归方法对甘南地区的积温和湿润度进行插值,建立了>0℃年积温和湿润度空间数据库.依据草原综合顺序分类法的分类原则,绘制了甘南地区的潜在草地类型图.结果表明,甘南草地共分为寒冷潮湿多雨冻原一高山草甸类、寒温潮湿寒温性针叶林类、微温潮湿针叶阔叶混交林类、微温湿润森林草原一落叶阔叶林类、暖温潮湿落叶阔叶林类、暖温湿润落叶阔叶林类、暖温微润森林草原类、暖温微干暖温带典型草原类、暖温干旱暖温带半荒漠类9种草地类型; 草地主要分布在海拔3 000~ 4 000 m,海拔和坡度的变化对草地类型的空间分布具有显著的影响
英文摘要	Grassland is the basis of the livestock industry. Scientific and reasonable method of grassland classification is essential for the development, protection and management of grassland. Based on meteorological information in 30 years from 55 meteorological stations located within Gannan Region and in surrounding areas, the spatial databases of >0 ℃ annual accumulated temperature and humidity grade were constructed with the methods of geo-statistics and mathematical regression. A potential grassland type map in Gannan Prefecture was made according to the method of Integrated Orderly Classification System of Grassland (IOCSG). The result of this study showed that 9 classes of grassland types were identified in the study area, including frigid perhumid rain tundra, alpine meadow class, cold temperate perhumid taiga forest class, cool temperate perhumid mixed coniferous broad leaved forest class, cool temperate humid forest steppe, deciduous broad leaved forest class, warm temperate perhumid deciduous broad leaved forest class, warm temperate humid deciduous broad leaved forest class, warm temperate subhumid forest steppe class, warm temperate semiarid warm temperate typical steppe class, warm temperate arid warm temperate zonal semidesert class. This study suggested that grassland mainly distributed regions within the elevation between 3 000 and 4 000 m and the elevation and slope significantly influenced spatial pattern of grassland
