在我国长达18000公里的海岸线上,大小岛屿星罗棋布,仅浙江省嵊泗一县就有196个之多,其中26个有人居住。目前海岛普遍缺少淡水的状况严重影响工农业生产和人民的生活。1975年上海市政工程设计院、上海市塑料配件厂和嵊泗县有关部门在泗礁本岛开展了海水淡化的研究,以探索利用自然资源和近代技术解决海岛供水的可行性。本文介绍该课题的中型试验情况。 In China’s 18,000-kilometer long coastline, large and small islands are dotted. There are only 196 of them in Yi County, Zhejiang Province, of which 26 are inhabited. At present, the general lack of fresh water in the islands has seriously affected industrial and agricultural production and people’s lives. In 1975, the Shanghai Municipal Engineering Design Institute, the Shanghai Plastic Parts Factory, and the Jixian County Department carried out research on seawater desalination on the Peacock Reef Island to explore the feasibility of using natural resources and modern technology to solve the island’s water supply. This article describes the medium-sized test of this topic.
