| 摘 要： | 淡水透镜体作为海岛主要的甚至是唯一的淡水资源，对其在天然和开采条件下的演变规律研究是海岛淡水资源利用和管理的首要任务。采用自制的室内物理模型，对海岛淡水透镜体的演变过程进行了模拟实验。模拟了降雨补给条件下淡水透镜体的形成过程；在无补给条件下，开采淡水时倒锥的变化过程。结果表明：当开采量达到3.73×10-5m3/s时，倒锥进入抽水井，淡水透镜体被击穿。

| Abstract: | Freshwater lens, as the main or even the only freshwater resources of island, it’s law of evolution in the condition of nature and exploitation has become the primary research content of island freshwater resources use and management. Using self-study model to simulate freshwater lens evolution at laboratory, it’s formation process in the condition of rainfall has been simulated, the process of upconing movement has also been simulated without any recharge. When the pumping rate reached 3.73 × 10-5m3/s,the upconing moved into pumping well and the freshwater lens was breakdown. |
