摘要:
祁连山垂直植被带沿海拔从低到高依次为荒漠草原带、干性灌丛草原带、山地森林草原带、亚高山灌丛草甸带、高山寒漠草甸带,在这些植被带上选择典型的植被类型设置样地,采用半微量凯氏、氢氧化钠-钼锑抗比色法、CaCO3分子式求法、土壤烘干法、环刀法等方法进行土壤特性相关因子调查分析。结果表明:1.荒漠草原带土壤有机质含量只有1.65%,全氮量和全磷量分别是0.14%和0.089%,含量最少,而干性灌丛草原带、山地森林草原带、亚高山灌丛草甸带土壤有机质含量相差不大,都在10%～12%之间变动。2.青海云杉林、高山灌丛林、祁连圆柏林、低山灌丛、牧坡草地、无林地其下0～60 cm的土壤容重依次增大,从0.53 ...
Abstract:
There are desert grassland，dry shrub grassland，mountain forest grassland，subalpine shrub meadow，alpine cold desert meadow on vertical vegetation belt along northern slope of Qilian Mountains,Gansu of China from low to high altitude. We set up sample plots on typical vegetation along these belts，and use the semimicro Kjeldahl，Sodium hydroxide and Mo-Sb anticolorimetric method，the CaCO3 molecular formula，soil drying method，ring sampler method to carry on correlation investigation and the analysis of soil different quality. The results showed that：1 Organic matter content of the desert grassland soil is only 1.65%，and total nitrogen and total phosphorus content are 0.14% and 0.089%，and content was the lowest，while organic matter content of dry shrub grassland，mountain forest grassland，subalpine shrub meadow soil is similar and change between 10% and 12%. 2 The soil volumeweight in 0~60 cm deep of Picea crassifolia，alpine brushwood，Sabian przewalskii，the low mountain brushwood，meadowland，open ground is increased in turn from 0.53 g/cm3 to 1.02 g/cm3 accordingly，the soil porosity reduced from 72.64% to 48.11%. 3 The number of dominant species in different types of soils on the north slope of Qilian Mountains was first increased and then decreased with the increase of altitude，that is to say，the inverted U type distribution trend. Understanding and grasping the response relationship between characteristics of soil and vegetation vertical distribution，which can provide technical support for vegetation restoration.
