【摘要】：為研究護(hù)坡毛竹根(莖)系的生長(zhǎng)、分布及其護(hù)坡效果,于2012—2016年對(duì)七星關(guān)區(qū)(原畢節(jié)市)何官屯鎮(zhèn)北部大漁洞村某處毛竹生態(tài)護(hù)坡措施進(jìn)行了為期5 a的調(diào)查監(jiān)測(cè)研究。通過(guò)實(shí)地挖根及動(dòng)態(tài)監(jiān)測(cè)技術(shù)方法對(duì)研究區(qū)毛竹根(莖)系的生長(zhǎng)、分布及其護(hù)坡效果等進(jìn)行了調(diào)查研究。結(jié)果表明:毛竹種植后,毛竹根(莖)系的生物量逐年增加,根狀莖的生物量增加速度高于根系的生物量增加速度;毛竹根(莖)系長(zhǎng)度在水平方向上逐年增加,但增加幅度逐年遞減,在2015—2016年研究區(qū)毛竹根(莖)系達(dá)到郁閉;研究區(qū)毛竹根(莖)系長(zhǎng)度在垂直水平方向上逐年增加,但幅度逐年遞減;研究區(qū)種植當(dāng)年的護(hù)坡效果不明顯,之后滑坡體沿坡面向下的平均位移量逐年遞減,且在2015—2016年有趨于穩(wěn)定的趨勢(shì)。綜合分析認(rèn)為:研究區(qū)毛竹護(hù)坡隨著種植年限增加,根系生長(zhǎng),其護(hù)坡能力大大增強(qiáng),滑坡體在2015—2016年趨于穩(wěn)定,毛竹護(hù)坡達(dá)到了預(yù)期的護(hù)坡效果,能夠?yàn)榻窈笸惖貐^(qū)滑坡的治理提供參考和借鑒作用。
[Abstract]:In order to study the growth, distribution and slope protection effect of Phyllostachys pubescens (stems) in slope protection, the ecological slope protection measures of Phyllostachys pubescens in the north of Heguantun Town, Qixingguan District (formerly Bijie City) were investigated and monitored for 5 years from 2012 to 2016. The growth, distribution and slope protection effect of Phyllostachys pubescens (stems) in the study area were investigated by the method of root-digging and dynamic monitoring. The results showed that the biomass of Phyllostachys pubescens root (stem) increased year by year, the biomass of rhizome increased faster than that of root, and the length of bamboo root (stem) increased year by year in horizontal direction. However, the increasing range decreased year by year, and the length of bamboo root (stem) line increased year by year in vertical horizontal direction, but decreased year by year in 2015-2016, and the length of Phyllostachys pubescens root (stem) line in the study area increased year by year, but the length of bamboo root (stem) line increased year by year. In the study area, the slope protection effect was not obvious in the year of planting, then the average displacement along the slope decreased year by year, and it tended to be stable in 2015-2016. The comprehensive analysis showed that the slope protection of Phyllostachys pubescens increased with the increase of planting years, the ability of slope protection was greatly enhanced, the slope body tended to be stable in 2015-2016, and the slope protection of Phyllostachys pubescens reached the expected slope protection effect. It can provide reference and reference for the control of landslide in the same area in the future.
