中文摘要：

人居环境自然适宜性是人类生存和发展的基础，从根本上制约着区域人口的集聚和发展。同时随着经济社会的发展，人居环境适宜性越来越受到社会的关注，相关研究也越来越深入，牵涉的方面也更加广泛。采用地形起伏度、地被指数、水文指数、气候适宜度四类指标加权求和的方法计算了云南省不同区域人居环境自然适宜性。研究结果将为云南省未来人口发展功能分区，人口空间优化分布，协调人口、资源、环境之间的关系提供重要参考。

英文摘要：

The natural suitability of the human settlements environment is the foundation of human existence and development. Meanwhile, with the development of the social economy, there is an increasingly concerning of the suitability of the human settlement environment, and the relative researches have been gradually deepening, related to much more extensive areas. It fundamentally constrains the cluster and development of regional population. The article has offered such methodologies as the relief degree of land surface （RDLS） , vegetation index, hydrology index, climate suitability to calculate the natural suitability of the human settlements environment in different regions in Yunnan Province. The results of the research will make an important reference for the function zoning of population development, the optimized distribution of the population space, and the coordinated relationship of the population, resources and the environment.
