| 摘 要： | 为了研究土壤生物工程措施在河流生态修复中效果,选择北京怀九一渡河段裸露坡岸为研究对象,针对该河段坡面存在着溅蚀,面蚀,沟蚀及侧渗侵蚀等土壤侵蚀现象,采用扦插、生物垫和梢捆3种土壤生物工程措施对河流岸坡进行治理,分别对施工4个月、8个月后植物的生长特征、稳固岸坡效果进行了调查观测,结果表明:在不同土壤生物工程措施下,成活金丝柳的生长情况均达到较高水平,但在以水分、覆土过厚等制约因素下,金丝柳的生长表现出明显差异;扦插措施根系扎根深,易成活,对深层土壤的加固作用良好;土壤生物工程施工后河流岸坡植物快速恢复,生物多样性增加。最后总结了北京地区土壤生物工程施工以及后期管理防护中的注意问题,以期为北京地区河流的生态治理提供一定的技术指导和理论支持。

| Abstract: | A bare river bank was selected at the Huaijiu River,Beijing,in order tO investigate and disseminate the positive effects of soil bioengineering techniques and options to establish riparian vegetation at local con- ditions.For the moment,the river bank is marked by diverse types of soil erosion such as contained splash e- rosion,soil surface erosion,gully erosion and seepage erosion.Three soil bioengineering measures as live cuttings,fascine and brush mattress were took to protect the river bank.The plant performance and slope stability were investigated after 4,8 month.The results show that:exist Salix X aureo-pendula is grows well under different soil bioengineering techniques.For such reasons like absence of water and superabun- dance soil covered,Salix X aureo-pendula survival rates varied considerably between the differently structure- d river bank zones the live stake has the deepen root system and has a good effect for stabilize the slope.A- long with the riverbank being reinforced,the habitats of the riparian zone are under self-improvement and plants have been in rapid restoration.The paper also summed up the notice during the construction and man- agement.The results will give some soil bioengineering techniques and theory basement to the river ecologi- cal restoration in Beijing. |
