河西内陆河不同流域盐碱土壤碳、氮、氢分布特征

利用元素分析仪测定了河西走廊不同地区盐碱土壤的碳、氮、氢含量,研究了其分布特征.结果表明,河西走廊内陆河不同流域地区盐碱土壤中的碳、氮、氢分布呈现出显著的地域特点.尤其是疏勒河流域,其碳、氮、氢总含量明显高于其它两个地区(黑河流域、石羊河流域),沿河西走廊从西向东,土壤中碳、氮、氢的总含量依次降低,土壤的肥沃程度也沿河...

The Distribution Characteristics of Carbon,Nitrogen and Hydrogen of Saline-alkali Soil in Different Inland River Basin of Hexi Areas

The elemental analyzer saline was used to determine soils carbon, hydrogen, nitrogen content in different areas of the Hexi Corridor. The results showed that it was significant geographical features which carbon, nitrogen, hydrogen distribution saline-alkali of different soil of the Hexi Corridor region of inland river basin. Especially in the Shule River, its carbon, nitrogen, hydrogen was significantly higher than the total content of the other two regions （Heihe basin, Shiyang River basin）, from west to east along the Hexi Corridor, the carbon, nitrogen, hydrogen of soil total in order to lower level, the soil fertility also from east to west along the Hexi Corridor in order to decreasing.
