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西走廊的从西往东走向依次降低。
The contents of carbon, nitrogen and hydrogen in saline-alkali soil in different areas of Hexi Corridor were measured by elemental analysis and their distribution characteristics were studied. The results show that the distribution of carbon, nitrogen and hydrogen in saline-alkali soil in different river basins in the Hexi Corridor exhibits significant regional characteristics. In particular, the total content of carbon, nitrogen and hydrogen in the Shulehe River Basin was significantly higher than that in the other two regions (Heihe River Basin and Shiyang River Basin). The total content of carbon, nitrogen and hydrogen in the soil along the Hexi Corridor from west to east was In turn, the fertility of the soil decreases along the Hexi Corridor from west to east.
