摘　　要：砂石资源是中国消耗第二大自然资源,支撑着经济社会的快速发展。对近年来湖北省河道砂石资源供应不足的原因进行了系统分析,并提出了缓解对策。研究结果表明:目前湖北省河道砂石资源供需困局的形成主要是由于长江干支流河道和湖泊来沙量锐减、河湖持续冲刷以及环保政策趋紧;随着上游干支流水库建成运用以及水土保持工作的持续开展,预计湖北省砂石资源供需矛盾将长期存在。通过加强河演趋势研判、动态调整长江及汉江干流可采区、合理规划和布局小支流及湖区采砂并及时补充其他砂源,能够提升湖北省砂石资源市场供应保障能力。Sand-gravel resource is the second largest natural resources consumed in China in recent years,supporting the rapid development of economy and society.In this paper,the causes of insufficient supply of river sand-gravel resources in Hubei Province in recent years were analyzed,then the countermeasures were presented.The analysis results showed that the problem between supply and demand of river sand-gravel resource in Hubei Province was mainly caused by the sharp decrease of sediment discharges in the Yangtze River and its tributaries,the continuous erosion of rivers and lakes,and the environmental protection policies.With the construction and operation of upstream reservoirs,and the continuous development of soil and water conservation,it was expected that the contradiction between supply and demand of water sand-gravel resource in Hubei Province will exist for a long time.By strengthening river evolution trend analysis,dynamically adjusting the mining areas in the Yangtze River and the Hanjiang River,reasonably planning sand mining in small tributaries and lake areas,and replenishment of other sand-gravel sources,the supply ability of the water sand-gravel resource in Hubei Province can be improved.
