Abstract: By using the method of multi-index extension comprehensive evaluation, the various factors affecting the development and utilization grade of the inhabited islands were analyzed,the matter-element model of the comprehensive evaluation of the development and utilization grades of the inhabited island were established, and its correlation degree was calculated. Quantitative numerical evaluation results were obtained. Taking the four inhabited islands in Taizhou City, Zhejiang Province as an example, the results show that the evaluation of the exploitation and utilization level of the inhabited islands by this method is more objective and reasonable. It can be used as evaluation models of development and utilizing classification for the inhabited islands.

Key words: extension mathematics, inhabited islands, development and utilization level, matter-element model
