北京是水资源严重紧缺的特大城市,超采地下水已经成为缓解全市水资源短缺的主要措施,导致全市超采区不断扩大,发生地面沉降等不可逆的生态环境问题,如何涵养地下水源、缓解水资源紧缺形势成为研究的热点。从种植结构调整对水资源利用影响效果的角度,围绕实际灌溉用水、植物耗水和不同下垫面类型对地下水回补的影响,探讨了粮田和林地对北京市地下水开发利用的影响,以期为北京市水资源高效利用提供参考。
Beijing is a mega-city where there is a serious shortage of water resources. Overexploitation of groundwater has become a major measure to alleviate the city’s water shortage and has led to the irreversible ecological and environmental problems such as land subsidence and other over-exploitation areas in the city. These problems include how to conserve underground water and ease water resources The shortage situation has become a research hot spot. From the perspective of the effect of planting structure adjustment on water resources utilization, this paper discussed the impact of grain fields and forestland on groundwater development and utilization in Beijing based on the influence of actual irrigation water, plant water consumption and different underlying surface types on groundwater recharge. Provide a reference for the efficient use of water resources in Beijing.
