| 摘 要： | 依据草原综合顺序分类系统,利用1950~2000年近50 a全球气候插值数据集,绘制出甘南地区的潜在草地类型图,并对甘南地区潜在草地NPP进行了统计分析。结果表明：甘南草地可分为寒冷潮湿多雨冻原-高山草甸类、寒温湿润山地草甸类、微温潮湿针叶阔叶混交林类、微温湿润森林草原-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和暖温微干暖温带典型草原类7类草地;甘南地区NPP年均值在空间上由西北向东南方向逐步增加,NPP总量为23.08 TgC,其中以寒冷潮湿多雨冻原-高山草甸类和寒温湿润山地草甸类草地类型为主;在地形因素中,海拔高度对NPP年均值的影响较明显,随着海拔增加NPP呈下降趋势,而坡度和坡向对于NPP年均值的影响不明显。

| Abstract: | According to Comprehensive Sequential Classification System(CSCS),potential grassland classification map was made and potential grassland NPP was statistical analyzed in Gannan by using of global climate interpolation data sets from 1950 to 2000.The result shows that grassland of Gannan can be classified into 7 classes,including Frigid perhumid rain tundra-alpine meadow class,Cold temperate-humid montane meadow class,Cool temperate perhumid mixed coniferous broad leaved forest class,Cool temperate-humid for... |
