我国的海岛,星罗棋布,有的远离海岸,有的地处海湾或近岸边。因此,这些海岛地区都有着一定贮量的海洋能源资源。诸如,潮汐、波浪、风力等。为了探索海岛能源的开发可行性,对于相当县级地区的海岛能源进行调查,就其全年的变化情况进行有目的观测,然后通过一定的统计分析,数据处理,从而得到宏观上的初步结论,为开发活动提供前期依据。为此,笔者提出以下统计方法,对海岛能源的年变化状况,进行概算,提出简单结论,供同行交流。我国海岛分布广泛,有的远离海岸,有的地处海湾内或靠近岸边,因此潮汐、波浪、风等海上自然资源也因地而异。为摸清海岛资源开发可行性,对于县级岛资源全年分布及变化 Our country’s islands are dotted, some are far from the coast, some are located on the gulf or the coast. Therefore, these island areas have some reserves of marine energy resources. Such as tides, waves, wind and so on. In order to explore the feasibility of island energy development, we surveyed the island energy resources in the equivalent county-level areas and observed the changes throughout the year. After some statistical analysis and data processing, we got the preliminary conclusions on the macro level, For the development of activities to provide a pre-basis. To this end, the author proposes the following statistical methods to estimate the annual changes of island energy resources and put forward simple conclusions for peer exchange. The islands in our country are widely distributed. Some of them are far away from the coast and some are located in the bay or near the shore. Therefore, the natural resources at sea such as tides, waves and winds also vary from place to place. In order to find out the feasibility of developing island resources, the distribution and changes of county-level resources throughout the year are discussed
