黄土高原人为加速侵蚀下水土与养分流失耦合研究

Shuitu Baochi Xuebao, 2011
利用野外模拟人工降雨试验,对人为加速侵蚀下耕地、草地和林地的水土与养分流失进行耦合研究。结果表明:人为加速侵蚀后养分随径流和泥沙的迁移,导致土壤肥力下降,其中泥沙结合态是养分流失的主要途径。耕地翻耕后加速土壤侵蚀,除产流量减少22.4%外,侵蚀速率和产沙量分别增加了27.1%和27.3%;总有机碳、总氮和总磷流失量分别增加104.5%,42.5%和59.5%。草地和林地的蓄水保土效果显著,开垦后侵蚀速率分别增加了188.9%和10 225.1%,产沙量分别增加了190.6%和9 370.0 ...

亚洲象冬季日粮营养分析及表观消化率测定

野生动物学报
在人工饲养亚洲象（Elephas maximus）的过程中，饲料营养是其健康状况的重要影响因素之一，但关于亚洲象饲料以及消化率相关的研究较少。为测定亚洲象日粮营养成分含量及摄入量、养分消化率，选取5头北京动物园圈养的成年亚洲象为试验动物，分析其冬季日粮的营养成分，同时收集粪便，测定其表观消化率。结果表明：亚洲象干物质采食量占其体质量的0.66% ~ 1.20%，个体间养分消化率存在差异。试验用饲料干物质、粗蛋白、粗纤维、粗脂肪、钙和磷的平均消化率分别为（51.0 ± 2.7）%、（67.2 ± 2.4）%
