黄河三角洲非常规水资源综合利用

Integrated utilization of unconventional water resources in Yellow River Delta

针对黄河三角洲地区水资源不足、对黄河客水依靠程度高、水资源供需矛盾突出等问题,提出通过建设滨海骨干生态河道、完善灌区灌排干支渠、增设必要蓄水设施、构建生态水网等实现非常规水资源的综合利用。初步估算黄河以北非常规水资源利用量可达22 390万m3/a,黄河以南非常规水资源利用量可达14550万m3/a,这部分水经深度处理后可作为黄河三角洲自然保护区湿地补水水源或当地工农业用水水源。

The water system in the Yellow River Delta is characterized by insufficient water resources, a strong dependency on the water from the Yellow River, and outstanding conflicts between water supply and water demand. With consideration of these characteristics, an integrated strategy for utilization of unconventional water resources was proposed through construction of coastal ecological river channels, improvement of irrigation, drainage, and storage facilities in irrigation areas, and establishment of ecological river networks. It was preliminarily estimated that the amount of available unconventional water could be 223.9 million cubic meters per year to the north of the Yellow River and 145.5 million cubic meters per year to the south of the Yellow River. After advanced treatment, the water can become a resource for nature reserve wetlands and local industry and agriculture.
