黄淮海平原水量变化对农业生产力的影响及对策

Effect of the water change on the agricultural production and its countermeasures in the Huang-Huai-Hai Plain

  • 摘要: 研究分析了黄淮海平原引黄灌溉的时空分布与增产效益,1990~1995年黄河下游引黄水量为107.8亿m3,1992~1996年引黄灌溉的增产效益粮食为2650kg/hm2,棉花为558kg/hm2。并简析了黄河断流的频率及其影响,1990~1998年洛口站累计断流天数为392d,利津站累计断流天数为859d。提出了水资源短缺地区农业水分管理对策,其中包括不同供水方案对农业生产的影响、粮食生产布局的区域调整与农业水分管理的开源节流措施。

     

    Abstract: The distributions of time and space and the yield-increasing benefits of waterdiverting irrigation from the Huanghe River in the Huang-Huai-Hai Plain were briefly researched. The amount of water-diverting was 10.78 billion m3 at the lower reaches of the river from 1990 to 1995. The yield-incr easing benefit of the irrigation was 2650kg/hm2 for grain, and 558kg/hm2 for cotton in the area from 1992 to 1996. The frequency and the effect of absence of flow in the river were analyzed. The accumulative water-off days were 392 days for Luokou Station and 859 days for Lijin Station from 1990 to 1998. The countermeasures of agricultural water management in the area where water resources are deficient were inquired into, that consist of the effects of the different water supply projects on the agricultural production, the region regulations of the grain production patterns and the measures of the developing resources and reducing expenditure for agricultural water management.
