Abstract:In scientific and rational village planning, how to protect and develop traditional villages according to local conditions is an urgent problem to be solved. In this study, 15 national traditional villages in Haikou City are selected as research objects. After obtaining the morphology and scale of the villages, ae well as the elevation, slope, water system, road and point of interest, a village morphological attribute database is constructed based on GIS. By analyzing the morphological types of traditional villages, the relationship between the morphological characteristics of different types of villages and physical geographical factors and socio-economic factors is summarized. Finally, the positioning of traditional villages in Haikou City is divided into three types: having perfect infrastructure and abundant resources, perfect infrastructure but poor resources, and imperfect infrastructure but and rich resources. And the study discusses the differentiated protection and development strategies of the three.
