摘　　要：护岸林是三峡水库能否长久运行的一项重要保障措施,对三峡库区涪陵段撑绿竹护岸林进行了详尽调查,并对其根系土壤作了详细分析,结果表明:三峡库区涪陵段撑绿竹护岸林有好的保持水土效益;撑绿竹护岸林的栽植密度达900丛/hm2,林下枯落物厚度在2.5cm以上时生态效益最佳。The retaining woodlands is the important protect measures if or not the Three Gorges reservoir area attaining long benefits. The study is proceeding detailed survey to Bambusa pervariabilis×Dendrocalamopsisi bank protection woodlands in the Three Gorges reservoir area, and detail analyzed the soil of its root systen. As the result express: Firstly,Bambusa pervariabilis×Dendrocalamopsisi bank protection woodlands are able to attain soil and water benefits in the Three Gorges reservoir area in Fuling region; Secondly,the soil is the main of loamy sandy soil,the best ecological benefits is densely degree to 900 bunch/hm^2, and the thickness of deadwood beyond 2.5 cm in the bank protection woodlands.
