This paper introduced the purpose, significance and method of analysis of sand resources storage in the Linwei section of lower reaches of Weihe River.Through exploration,it preliminarily identificated 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 cubic 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 mining 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.
