摘　　要：为研究毛竹生态护坡的护坡效果和经济效益,2012~2017年间,针对某一试验区的滑坡体位移、滑落塌陷情况以及毛竹种植经济效益等进行了为期6 a的监测研究。结果表明:随着毛竹的生长,护坡作用越来越明显,毛竹的护坡功能有随着年份的增加而逐渐加强的趋势;毛竹对维护滑坡体稳定有着积极的作用,但这种作用的稳定发挥需要3~4 a;毛竹被采伐后,新发竹笋数量明显增加,且竹笋生长迅速,郁闭较快,能够有效地防止坡面水土流失;种植毛竹能够在护坡的同时增加经济收入,可大范围推广。研究成果对生态护坡技术和研发具有一定参考价值。To study the ecological bamboo slope protection effect and economic benefits,during 2012 ~ 2017,we carried out a six-year monitoring to the experimental area,and the research includes landslide displacement,slipping collapsing and economic benefits. The results show that with the growth of bamboo,the slope protection effect also increases; bamboo plays a positive role in maintaining stability of landslide,but this effect takes 3 ~ 4 years to develop; after the bamboo is felled,the bamboo shoots grow fast to become crown closure,so the soil loss is avoided; also the bamboo planting can increase the farmer income,which could be widely promoted.
