| In areas with unique traditional customs,it is of great significance to study the ecological network relationship between green space and residential space.In order to understand the characteristics of green space and living space in traditional villages of Bai nationality in Yunnan and find out its influencing factors and maintenance mechanism,we selected five traditional villages in Dali Bai Autonomous Prefecture for data collection of green space network and living space network,and constructed a series of quantitative indicators,network models and spatial network index systems.The characteristics and influencing factors of green space,living space,ecological network of green space and living space in traditional villages of Bai nationality in Yunnan were studied comprehensively by means of network analysis,spatial connectivity analysis and correlation analysis.It provides new research ideas and theoretical support for the construction,protection,renewal,development and utilization of Bai traditional villages.The results showed that:(1)In the living space of the five Bai traditional villages of Sideng,Nuodeng,Baofeng,Xizhou and Hecun,the overall completeness of Sideng and Xizhou was relatively good,followed by the overall network completeness of Baofeng and Hecun,and the overall completeness of Nuodeng was the lowest.The overall stability of the residential space network of each village was high,and the local stability of the residential space ecological network of Sideng Village was better than that of the other four villages.Among the five villages,only the living space of Nuodeng ancient village had the highest vulnerability;the residential space network aggregation of Sideng and Xizhou was the highest,and the residential space network aggregation of Nuodenggu Village was the lowest.There were multiple central potential areas in the residential space network of the five villages,and these residential space nodes closer to the center were mostly schools,ancient buildings,characteristic activity centers,commercial centers,entrance service buildings and other residential space areas with high population aggregation,and the interaction between the crowd and them was high.(2)In the three villages of Sideng,Baofeng and Hecun,there was a strong traction effect in the ecological space types of water green space.This traction strength was usually between waters and waters,between waters and other green space types.The correlation between water area and water area was very high,mainly because there were usually landscape bridges and galleries in this type of water landscape in the village to divide the water body and form different water features,which was also the characteristic of the village.The scale of the living ecological space in the four villages of Luosideng,Baofeng,Xizhou and Hecun was larger and the correlation phenomenon was more common.There was a scale effect of radiation with one of the living spaces as the radiation center.(3)The overall level of ecological network of Sideng,Nuodeng and Baofeng green space in the five Bai traditional villages of Sideng,Nuodeng,Baofeng was close,while the overall level of Xizhou and Hecun was low.The overall network completeness of Sideng,Nuodeng and Baofeng green space was good,and the overall completeness of Hecun green space was the lowest.In the green space network of the five traditional villages of the five Bai ethnic groups,the overall stability of the Hecun Village was the highest,the overall stability of the Nuodeng Green Space was the lowest,and the overall stability of the Sideng,Baofeng,and Hecun Green Spaces was not much different and was at a medium level;there were multiple central potential areas in the green space network of the five villages.The green space nodes closer to the center in the four villages of Sideng,Nuodeng,Baofeng and Hecun all appear water area(RS)type.The green space nodes closer to the center in the four villages of Sideng,Xizhou,Baofeng and Hecun all appear public activity(PSF)green space type.(4)Sideng,Nuodeng,Baofeng,Xizhou and Hecun five Bai traditional village green space and living space in Sideng,He village green space and living space ecological network overall level was higher,and Xizhou green space and living space overall level was low,Sideng,He village green space and living space overall network completeness are good,Nuodeng green space and living space overall completeness was low;there were multiple central potential areas in the five village green space and residential space networks,and there are more network nodes closer to the center.The residential space nodes closer to the center of Sideng Village were mostly key protection buildings and a little improvement buildings.(5)The centrality,stability and vulnerability of village green space and residential space were affected by both natural and human factors.There were significant correlations between the centrality,stability and vulnerability of green residential areas in each village and the perimeter(SL),area(Si),comprehensive value(Vi),functional value(Mi),and geographical X and Y coordinates.This study reveals the interaction relationship and influencing factors between the green space network and the living space network of Bai traditional villages in Yunnan,and provides theoretical guidance for the protection of green space and living space ecological network of Bai traditional villages. |
