| 摘 要： | 对昆仑山天然草地实地考察,采集混合草群样品分析其化学成分,按照全国统一标准和方法对昆仑山天然草地进行了营养类型划分。结果表明,昆仑山西段的天然草地可分为4个营养型,分布于低山带的草地是碳氮-灰分型,在中低山分布面积较广的是氮碳-灰分型,在海拔3200～3600m的亚高山草地的营养型为碳氮型,在海拔3600～4000m的高山区为氮碳型。这是由于不同的生境生长着与之相适应的植物种类,在特定的物候期就具有不同的营养类型。 |

| Abstract: | Through investigating and collecting the blend sample of natural grassland in Kunlun Mountains,adopting countrywide standard and way,the nutritive types of natural grassland in the western zone of Kunlun Mountains were classified by analysing chemical component.It was divided into 4 nutritive types of the natural grassland in the western zone of Kunlun Mountains.Grassland distributing low mountain zone was carbon nitrogen-ash type,low-middle mountain zone was nitrogen carbon-ash type,sub-alp between 3200~3600m altitude was carbon-nitrogen type and alp between 3600~4000m altitude was nitrogen-carbon type.This is because different plant categories adapt to different living environment,and it have different nutritive types in particular growing periods. |
