摘  要:
在坡度大于60°、岩石单轴饱和抗压强度大于30Mpa并且完整性指数大于0.65、边坡最大相对高差105 m的废弃矿山高陡边坡上,采用砼浇筑种植槽、槽板上下间距(2.8±0.2)m、槽内充填基质并种植爬山虎(Parthenocissus tricuspidata)和凌霄(Campsis grandiflora)上爬植物、云南黄馨(Jasminum mesnyi)和月季(Rosachinensis)下挂植物、女贞(Ligustrum lucidum)和美丽胡枝子(Lespedeza formosa)等中间挡植物,经4年的生长,边坡绿化总体覆盖率由种植时的30%提高到95%,但绿化植物生长量较小,槽内基质有机质含量有所增加,氮磷钾养分含量逐年减少;建议在基质内适当添加生物菌肥和合理选择具有固氮和自然更新能力较强树种,以增强边坡植物群落稳定性和维持边坡绿化景观。

摘  要:
Experiments were conducted on greening on steep slope over 60o,with rock uniaxial compressive strength over 30 Mpa,index of rock mass integrality over 0.65,maximum relative height difference of 105 meters.The experiment was carried out in an abandoned mine in Shaoxing,Zhejiang province by planting different tree and shrub species in concrete castings with spacing of 2.8±0.2m.Four years observation demonstrated that greening area increased from 30% to 90%.But caused by small increment,organic materials increased in the concrete castings with decrease of N,P,and K content.Advices were offered such as adding in biological fertilizer,selecting stronger regeneration tree species.
