北京密云石匣小流域水土保持措施对土壤侵蚀的影响研究

open access: yesShuitu Baochi Xuebao, 2001
水土保持措施的实施可有效地控制土壤侵蚀 ,不同的水土保持措施存在不同的水土保持效益值。利用北京密云石匣共 2 0个坡面径流试验小区的野外观测资料 ,分析得出了北京石匣小流域不同水土保持措施下的水土保持效益值 ,其中免耕 (玉米 )为 0 .2 80 ,梯田 (玉米 )为 0 .142 ,人工草地为 0 .0 6 3,荒草地为 0 .0 45 ,水平条林地为0 .0 2 5 ,鱼鳞坑林地为 0 .0 19。人工草地、荒草地、水平条林地和鱼鳞坑林地有显著的水土保持效益 ,但它们之间的水土保持效益并无显著差别。

坡耕地不同水土保持措施下的养分平衡和土壤肥力变化

open access: yesShuitu Baochi Xuebao, 2002
在贵州省罗甸县坡耕地上布置长期定位试验 ,研究几种水土保持措施对作物产量和土壤肥力变化的影响。9年的测试结果表明 ,在旱坡耕地上 ,水土流失是造成坡地地力下降、养分损失 ,的主要原因。未采用水土保持措施的坡地种植 ,因水土流失产生的全氮、全磷、有效钾损失 ,分别占总养分消耗量的 5 3.0 % ,6 7.6 %和 19.0 % ,相当于施入土壤的氮素化肥 ,施入的有机和无机磷素 ,有机质的损失与施入的有机肥中有机质含量相当 ,土壤全氮、有机质和有效钾含量趋于下降 ,全磷维持在较低的水平 ...
