A toponymic cultural heritage protection evaluation method considering environmental effects in a context of cultural tourism integration

As a combination of toponym and cultural heritage with rich connotation of toponymic word-culture and entity-culture, toponymic cultural heritage has the significance of protection and inheritance. It is important for transmitting culture and expanding the cultural connotations of tourism activities. Previous analyses of such heritage protection and tourism exploitation mostly concentrated on resource value from an internal perspective, and the researches focused on toponymic words while paying less attention to toponymic cultural heritage entities, neglecting the influence of environmental condition. This study selected an ecologically and culturally sensitive region with environmental complexity and cultural diversity as an example and constructed a toponym database from multi-source heterogeneous toponym data; screened out toponymic cultural heritages based on a decision tree model; constructed an evaluation model of heritage protection value based on internal and external conditions by considering environmental effects, including toponymic words and entities; complemented an environmental condition evaluation by including natural and man-made disturbances; further widened resource value evaluation dimension with expert judgment and public judgment; and formulated a relatively comprehensive protection value assessment for such heritage.
