摘　　要：[目的]研究不同土壤生物工程措施植物随时间推移的发展特征及差异性。[方法]以旱柳活枝条为研究对象,在40 m的人工边坡上设置扦插、灌丛垫、层栽与梢捆4种土壤生物工程措施,对其完工后4、8、12个月的植物生长特征进行调查。[结果]4～12个月梢捆措施覆盖度从35%减少至20%,其他3种措施从40%增加到82.2%;扦插措施生长状况和其他措施存在显著差异,其生长状况由好到差依次为扦插、灌丛垫、层栽、梢捆;4种措施新生植株4～8个月的平均株高增长率在54.7%～82.3%,平均基径增长率在34.4%～75.0%;8～12个月平均株高增长率在28.9%～62.4%,平均基径增长率在29.1%～65.9%。4～8个月植物的生长速度高于8～12个月。[结论]扦插与层栽措施可快速且有效地稳固深层土壤,灌丛垫与梢捆措施在施工初期就可以很好地起到保护边坡不受水流冲刷的作用,防止表土侵蚀。[Objective]In order to study the development characteristics and difference of plants treated by different soil bioengineering measuresover time.[Method]With live plants branch as the research object, in 40 m set on artificial slope cutting, scrub pads, planted with tip bundle offour kinds of soil biological engineering measures,the growth characters of plants after 4,8,12 months were studied.[Result]The coverage of thetrusses of 4-12 months was reduced from 35% to 20%, and the other three measures increased from 40% to 82.2%.The growth status of cuttagemeasures and other measures were significantly different, and the growth condition was from good to poor, which was to root 〉 layer of 〉 layer ofBBB.The average plant growth rate of 4-8 months was between 54.7% and 82.3%, and the average basal diameter growth rate was 34.4%-75.0%. The average growth rate of the average plant in August and December was 28.9% to 62.4%, and the average growth rate was 29.1% to65.9%. The growth rate of plants in April and August was higher than that in August and December. [Conclusion]Cutting layer and plant meas-ures can be rapid and effective solid deep soil, scrub pads and tip bundle of measures at the beginning of the construction can be very good toprotect slope from water flushing action, prevent the erosion of topsoil.
