介绍了渭河下游临渭区开展砂石资源贮量分析的目的、意义与工作方法，通过勘探初步查明了临渭区河段空间分布、静贮量，对砂石质量进行了评价。结果表明：临渭区河段砂石资源埋深介于2．9～10．6 m，可用砂层平均厚度为13．06 m，静态贮量为6812万m3，主槽中的中粗砂可以作为3区建筑用砂，筛选后有可能达到2区用砂。分析了采砂对河道的影响，根据实测资料得到临渭区河段砂石多年平均可能静态补给量约为252万m3，并提出了在实际采砂管理中应采取的措施。

This paper introduced the purpose , significance and method of analysis of sand resources stor-age in the Linwei section of lower reaches of Weihe River .Through exploration ,it preliminarily identificat-ed the static storage and spatial distribution of sand resources in the area , and evaluated the quality of gravel.The results show that the depth of sand resources in the Linwei section is from 2.9 to 10.6 meters, the average thickness of used sand layer is 13.06 meters,the static storage capacity is 68.12 million cu-bic meters,the sand of main channel can be used as building sand of the third district and after screening the sand is likely to reach the standard of the second district .The paper analyzed the impact of sand min-ing on river .In accordance with the measured data ,it analyzed the average capacity of static recharge for many years which is about 2 .52 million cubic meters .Finally the paper put forward some measures to be taken in the actual management of sand mining .
