风水复合侵蚀对团聚体有机碳及其组分的影响

Shuitu Baochi Xuebao
目的为探究黄土高原风水复合侵蚀对土壤团聚体有机碳的影响。方法通过室内模拟降雨及风洞试验，研究不同侵蚀营力和侵蚀顺序下5~2 mm土壤团聚体有机碳及其活性碳组分的流失机制。结果1）风水复合侵蚀下土壤团聚体有机碳（SOC）、易氧化有机碳（EOC）、颗粒态有机碳（POC）、可溶性有机碳（DOC）质量分数较单营力侵蚀分别降低7%~25%、8%~29%、52%~71%、16%~32%。2）风水复合侵蚀中先风后水侵蚀（WR）下，SOC、EOC、POC、DOC、微生物生物量碳（MBC）质量分数较先水后风侵蚀（RW ...

石羊河流域干旱荒漠区人工梭梭林对土壤碳库的影响

Shuitu Baochi Xuebao, 2018
采用野外调查与室内分析相结合的方法，研究石羊河流域民勤干旱沙区种植人工梭梭林4，13，36年后的土壤有机碳（Soil organic carbon，SOC）、无机碳（Soil inorganic carbon，SIC）、全氮（Total nitrogen，TN）和总碳（soil total carbon，TC）含量及储量变化特征。结果表明：流动沙地种植梭梭后，0-50 cm层灌丛下和行间SOC和TN含量总体随造林年限增加而增加，5-50 cm层灌丛下SIC含量在13年梭梭林地最高。36，13年林地0 ...

三峡水库消落带泥沙淤积层水肥特性高程梯度分异

Shuitu Baochi Xuebao
目的研究水库消落带泥沙淤积层的水肥特性高程梯度分异可为水库科学管理提供依据。方法以三峡水库消落带为研究对象，采集典型坡面不同高程位置淤积泥沙分层样品，测试颗粒（黏粒、粉粒和砂粒）组成、养分物质（总有机碳、全氮和全磷）质量分数和质量含水率，对比分析消落带不同高程位置泥沙的水肥特性差异。结果1） 消落带淤积泥沙的颗粒较细，中值粒径为6.1~13.5 μm，平均值为8.7 μm，不同高程位置的泥沙中值粒径差异不显著（p>0.05）。淤积泥沙的颗粒组成以粉粒为主，平均体积分数为82.7 ...
