【摘要】：黄河是多泥沙河流,但泥沙地区分布不均,各河段河道演变与泥沙补给条件不尽相同,能直接用于建筑的砂石比较少,存在非法开采砂石现象,威胁防洪安全。为实现科学、可控、有序管理,研究提出了采砂控制总量、禁采区范围、可采区范围、可采区控制开采高程、禁采期、采砂作业条件、保留区范围、保留区转化条件等采砂管理控制性指标。在维护河势稳定,保障防洪安全、航运安全和供水安全,满足生态环境保护要求的前提下,在规划范围贵德至循化、兰州、宁夏至黄河入海口干流河段和湟水、清水河、窟野河等12条支流以及东平湖老湖区内,划定禁止采砂的禁采区81个,允许砂石开采的可采区301个,保留区178个。提出黄河流域干流禹门口以上河段和支流、湖区建筑用年度采砂控制总量为6 824万t,并提出了采砂保障措施及能力建设方案。
[Abstract]:The Yellow River is a multi-sediment river, but the distribution of the sediment is not uniform, and the channel evolution of each reach is different from that of the sediment, and can be directly used for the sand and stone of the building, and the phenomenon of illegal exploitation of sand and gravel is existed, and the safety of flood control is threatened. In order to realize the scientific, controllable and orderly management, the control indexes of sand mining, such as the total amount of sand mining control, the range of the forbidden mining area, the range of the mining area, the control and mining elevation of the mining area, the forbidden period, the working conditions of the sand mining, the scope of the reserved area, the conversion conditions of the reserved area, etc., are put forward. Under the premise of maintaining the stability of the river, ensuring the safety of the flood control, the safety of the navigation and the safety of the water supply and meeting the requirements of the ecological environment protection, under the premise that the requirements of the ecological environment protection are met, the river reaches of the main stream of the estuary of Lanzhou, Ningxia to the Yellow River and the water and the water and the clear water are in the planning range, Among the 12 tributaries and the old lake area of the Dongping Lake, there are 81 forbidden mining areas for the production of sand and sand, and there are 301 mining areas and 178 reserved areas for the production of sand and stone. The total amount of sand mining in the area for construction in the lake area is 62.4 million t, and the measures of sand mining and capacity-building are put forward.
