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 ...

桑干河流域淤地坝沉积泥沙特征及其来源解析

Shuitu Baochi Xuebao
[目的] 为查明桑干河流域的泥沙主要策源地和侵蚀产沙变化。[方法] 选取阳原县高墙乡典型淤地坝沉积泥沙为研究对象,利用复合指纹识别技术,测定沉积泥沙及其源地的土壤粒径、SOC、TN、137Cs、低频质量磁化率等9种指纹因子,研究了不同淤积阶段的泥沙策源地及坝控小流域侵蚀产沙演变规律。[结果] (1)沉积泥沙中137Cs平均含量较低,与沟壁土壤无显著差异(p>0.05),但极显著小于林草地和耕地的137Cs含量(p耕地(15.36%±8.46%)>林草地(1.96%±0.33%);(3 ...
