岛群开发时序优化模型构建及方法研究

The Formation of the Optimized Time Sequence Model of the Islands' Development and Its Method Research

岛群是海岛集聚分布所形成的地理单元,往往具有独特的地理区位优势和巨大的经济发展潜力。基于经济地理学中的增长极理论,构建了岛群开发时序优化的基础模型,并对岛群开发时空优化方法进行了系统研究;在此基础上,增加海岛异质性假设条件,以岛屿生态环境脆弱性为例对基础模型加以扩展,并根据循环积累因果原理,将时间变量引入模型,构建了岛群开发时序优化综合模型。结果表明,不同的开发时序,会使岛群开发的最终效果产生显著差异,岛群开发时序优化模型的建立对于实现岛群整体效益的最大化具有重要意义。

The island group is a geographical unit formed by the aggregated distribution of islands, which has unique geographical advantages and huge potential for economic development. This article establishes an optimized time sequence model for the development of island group based on the growth pole theory and studies the realization method of it systematically. The basic model is expanded when considering the islands＇ heterogeneity. At the same time, an example is provided based on the islands＇ environmental vulnerability. Finally, the time factor is added to the model according to the principle of Cycle Accumulation Cause to formulate the integrated model. It is proved that different development sequence can result in different ultimate benefit. So it is essential to optimize the development sequence of the island group to pursue the maximization of benefits.
