摘　　要：通过对粗泥沙集中来源区拦沙工程建设成就与问题的分析,结合粗泥沙集中来源区沟道特征,提出了粗泥沙集中来源区拦沙工程体系的构成、布局思路、建设原则,提出了“先大后小”、“先下后上”和“分段实施”的拦沙工程建设时序,并针对当前工作实际,提出了亟待解决的几个问题:加快大型拦泥库前期工作步伐、尽快制定大型拦泥库标准、重视各类工程实施进度以及正确理解和执行规范、充分发挥骨干坝的作用等。The paper puts forward the structure of debris-retaining works system,layout consideration and construction principle for the coarse sand concentrated coming area,time sequence of the works construction of 'large-scale first and small-scale second','downstream first and upper stream second' and 'carrying out section by section' and some problems demanding prompt solution according to the present facts and;to speed up the preparation of a large-scale debris-retaining reservoir;to draft the standards for a large-scale debris-retaining reservoir as quick as possible and;lay emphasis on the schedule of various projects and correct understanding and fully playing the function of key dams through the analysis on achievements and problems of debris-retaining works building and combining with the gully characteristics of coarse sand concentrated coming area.
