摘要
近年来黄河大北干流河道采砂量不断增大,对该河段河道冲淤变化、防洪安全、生态环境等方面的影响日渐凸显,但是对于河道实际采砂量目前还没有确切的统计数据.通过现场调查、地区经济指标估算等方法对黄河大北干流的年采砂量进行统计计算,结果表明:实地调查河段年均采砂量为0.3亿t,地区经济指标估算河段采砂量为0.35亿t,二者相差不大.通过不同年份场次洪水河段冲淤量分析得知,河道采砂对河段冲淤变化产生了一定的影响.
In recent years, the amount of sandexcavation from the Dabeiganliu reach of the Yellow River has been increasing. The influence on the variation of erosion and deposition of the channel, the flood control security and ecological environment of the river is becoming more and more prominent. However, there are no exact statistics on the actual amount of sand excavation of the river. The annual amount of sand excavation from the main channel was calculated systematically by means of field investigation and regional economic sand estimation. The re-sults show that the average annual sand collection in the field survey reaches 30 million tones, and the estimated sand excavation in the re-gional economy is 35 million tones, which is not much difference. According to the analysis of the amount of erosion and deposition in the flood river section in different years, the sand excavation from the river has a certain influence to the variation of erosion and deposition of the section.
