边远海岛水资源开发利用模式研究

Study of water resources exploitation and utilization model for remote islands

以舟山群岛为研究对象,通过分析海岛水资源特点及开发利用现状,探讨海岛地区水资源开发利用模式,提出了以保供水为主,结合防洪水、排涝水、抓节水、治污水的综合性开发利用模式——all in use(AIU)模式。针对用水需求年内变幅明显、水面蒸发量大、生态环境保护要求高的边远海岛,提出了以地下水库为存储空间,以截洪沟拦截汇水,以竖井收集来水的开发利用模式,最大限度地利用天然径流,形成水资源高效利用体系。

Using the Zhoushan Archipelago as the study area, we investigated the status of exploitation and utilization of water resources of the islands through analysis of the characteristics and current status of the water resources. We put forward a comprehensive exploitation and utilization model called AIU （ all in use ） , which focuses on water supply and involves flood control, drainage, water conservation, and water pollution control. Considering the fluctuation of water demands over a year, the large amount of evaporation from the water surface, and the high requirements of environmental protection on remote islands, we developed a high-efficiency water utilization system, which uses reservoirs as the storage space, intercepts catchment runoff with an intercepting trench, and collects water with shafts, in order to make the most of natural runoff.
