| 摘 要： | 保证人工客土基质能够长期有效的粘附在高陡石质边坡上,是实现高陡石质边坡人工生态工程恢复技术成功应用的重要先决条件.对利用水泥、稻草和复合肥改进后的人工基质,通过不同时间取样(取样17次)进行其侵蚀性和养分流失特性的研究.结果表明:经过改良后的人工基质泥土流失量及全氮、全磷、氨态氮、硝态氮、速效磷等养分的损失量均随植物生长期的延长而呈显著下降趋势,在发芽30d后,泥土的流失量几乎降低到了初始状态的1/5左右.全氮流失量较大,是全磷的2～3倍,其中硝态氮损失速率整体上均高于氨态氮. |

| Abstract: | To ensure artificial soil substrate to stick onto high rocky slopes for a long time is a prerequisite for successful application of eco-engineering technique in restoration of ecology of high rocky slopes. The artificial soil substrate was made with cement, rice stalk and compound fertilizer and applied onto the high rocky slope and sampled 17 times at different sampling time to observe its erosion and nutrient loss. Results showed that the soil loss and nutrient loss such as total N, total P, NO3--N, NH4+-... |
