- Title:
- Study on the Efficient Technique of Utilization Rainwater Resources in Semiarid Hilly Area of Southern Ningxia
- Keywords:
- semiarid hilly area of Southern Ningxia; rainwater resources; efficient technique of rainwater utilization

- 摘要:
- 计算了宁南半干旱山区上黄示范区的雨水就地利用和径流资源量雨水就地入渗集蓄量95.23×104m3，占雨水资源理论潜力29.65%。雨水径流资源量为15.85×104m3，占雨水资源理论潜力的5.85%，而目前示范区对降雨径流的集蓄能力仅为径流资源总量的17.35%，开发潜力较大。开展了多年的雨水资源就地利用和异地利用技术系统研究，总结出了适宜本地区提高雨水资源利用效率和经济效益的综合技术。
- Abstract:
- According to the actuality of land use and rainwater data, the amount of rainwater infiltration in same spot and run-off were estimated in Shanghuang demonstration, Guyuan, Southern Ningxia semiarid hilly area. They are 95.23×104 m3 and 15.85×10~4 m3 especially as much 29.65% and 5.85% as the potential of theoretical resources of rainwater. There is more potential of catchment to exert because the capacity of cellor water harvesting is 17.35% of runoff resource in the demonstration recently. On the base of series of experiments on the technique of handy and foreign utilization of rainwater, the integrative technique of efficient use of rainwater was summarized which is feasible in Southern Ningxia semiarid hilly area.
