Study on space diversity and influencing factors of Tunpu settlement in central Guizhou Province of China

Abstract

AbstractThe Tunpu settlements are the historical product of the co-evolution development of the unique geographical and cultural environment of Guizhou and the military defense policies of Ming Dynasty (1368–1644 AD), which created products such as the station troops and station farms. In this study, taking 10 Tunpu settlements in central Guizhou as the research objects, the space diversity of the Tunpu settlement and its influencing factors were analyzed based on the theory and calculation method of plant community species diversity. The results showed that: (1) On the whole, the space α-diversities of the military Tunpu settlements and the commercial Tunpu settlements were relatively high, with strong spatial similarity, while the residential Tunpu settlements had a lower degree of space α-diversity and significant difference. The space α-diversity of different types of the Tunpu settlement presents a variety of changes from the core protected areas to coordinated control areas. (2) There was a significant correlation between the spatial network and spatial morphological indicators and space β-diversity among the Tunpu settlement, and the stepwise regression showed that spatial morphological indicators had a strong explanatory power for the space β-diversity among the Tunpu settlements. (3) The space diversities of the Tunpu settlements were affected by the multiple synergies of natural environment, policy support, social-economic factors and cultural customs. Among them, policy factors and cultural factors were the dominant factors in the space diversity characteristics of the Tunpu settlements. By analyzing the space diversity law and its driving factors of the Tunpu settlements, this study could provide an important scientific basis for the protection planning and management of traditional settlements.
