黄河三角洲地区南部广饶县处于淄河冲洪积平原与三角洲海积冲积平原交接部位,因形成以花园和稻庄为中心的地下水降落漏斗而造成北部咸水以3.0km~2/a的速度向南入侵。建立该区地下水、地表水和引黄河水多水源联合调度优化模型,其目标函数是使各时段研究区地下水位降深之和最小,其约束条件包括供水量、开采井取水量、引黄河水量、节水量、水位等。预测结果表明,每个区采取包括节水、减少地下水开采量、拦蓄地表水或引黄河水补给地下水、井灌区改为渠灌等不同措施,到2010年,花园和稻庄漏斗中心水位将分别由过去的低于-20.00m上升为-14.00m和-12.66m; 2003年后,能够在稻庄北部形成反漏斗(淡水帷幕),阻止北部咸水入侵。环境效应显著。
Guangrao County, in the southern part of the Yellow River Delta, is located at the junction of the alluvial plain of the Zihe River and the alluvial plain of the delta. Due to the formation of a groundwater descent funnel with a focus on the garden and the rice paddy, the northern saltwater reaches a speed of 3.0 km ~ 2 / a South invasion. The joint optimization model of groundwater, surface water and water diversion from the Yellow River in this area is established. The objective function of this model is to minimize the sum of the groundwater table depths in the study area in each period. The constraints include the water supply, the water withdrawal of production wells, , Water saving, water level and so on. The forecast results show that different measures such as saving water, reducing the exploitation of groundwater, intercepting surface water or diverting water from the Yellow River to groundwater irrigation and replacing canals with canal irrigation are adopted in each district. By 2010, the water levels in the garden and the rice hopper funnel will be respectively From the previous less than -20.00m to -14.00m and -12.66m; after 2003, it is possible to form an anti-funnel (freshwater curtain) in the northern part of the rice paddy to prevent the invading salt water in the north. Significant environmental effects.
