基于数据分析方法的有居民海岛分类评价研究

海岛是我国国土重要的组成部分，是具有特殊性质的独立地理单元。海岛进行分类评价对海岛的开发和保护意义重大。文章选择30个海岛，从环境保护、经济发展和社会发展3个方面建立16个指标，通过聚类分析、主坐标分析和主成分分析，对海岛进行分类，同时研究海岛不同指标之间的关系。研究发现，海岛可以分为经济发展型、环境发展型和传统发展型3类。海岛的经济发展与社会发展表现出了较强的相关性，环境发展与社会发展表现出了较弱的相关性，经济发展与环境发展相关性很弱。通过对海岛进行分类评价，一方面可以深层次地了解海岛现状，同时也可以更好地把握海岛开发利用与环境保护之间的关系。

Research of Islands Classification and Evaluation Based on Data Analysis Methods

Islands,as an important land part of China,are independent geographical unit with special property.It is of great significance for exploitation and protection of islands that give them a correct classification evaluation.In this study,30 islands were chosen with 16 different factors include environment protection,economic and social development to realize the classification of them.Meanwhile the relationship between different factors that can give a direction of developing islands was explored.The study showed that the islands could be classified by economic developing islands,environment developing islands and traditional islands.The economic development had a strong correlation to the social development and the environment had a weak correlation to the social development.The economic development had very few correlation to the environment.Through the islands classification and evaluation,on the one hand the current situation of islands could be deeply discovered,on the other hand the relationship between the exploitation and protection of islands could be grasped in a better field.
