摘　　要：气候条件,主要是热量和水分以及二者的配合状况,是决定许多植被类型呈带状分布的根本因素。本文以位于我国三大气候分区过渡带中的河西走廊南部的祁连山为研究对象,借助遥感数据中的植被指数方法定量地描述该地区植被的生长状况和空间分布,结合相应的降水与气温的空间化栅格数据,通过GIS空间叠加与多因子复合分析,合理地揭示了水热组合对于植被分布的影响。Climatic conditions,mainly heat and water as well as the combination of these two factors,are the fundamental factors that decide the zonal distribution of different vegetation types.Qilian Mountain in the south of Hexi Corridor which locates in China s major climatic transitional zone was schosen as the study area and the remote sensing vegetation indexes were used as the quantitative methods to describe the growth status and spatial distribution of vegetation cover in the region.Besides that,the precipita...
