Research on Climate Adaptation of Bayu Traditional Settlements
(Lodz University of Technology Press, 2023) Li Xu; Wang Xiaofang
The form deeply affects the use of mountain topography and wind environment in the Bayu region are complex and diverse, and the spatial forms of traditional settlements are unique and rich. Studying their spatial patterns and mechanisms which adapt to the local climate will help to explore theories and methods of climate adaptability with low regional energy consumption. Taking 18 national historical and cultural towns in the Bayu region as examples, this paper uses historical documents and remote sensing information, integrates GIS morphological analysis, wind field simulation and actual measurement to analyze the correlation between the mountain terrain, the wind and the form of landscape pattern, street structure and building layout. The result shows that Bayu ancient towns are preferentially located in the flat dam area of hilly Valley or well-ventilated trough (gorge) Valley, and avoid the mountain top and low-lying calm wind area with violent air flow change. They often face the water and sit with their back against mountains, so they could avoid the chilly wind in winter and introduce cool wind in summer. The street is parallel to or forms an included angle of less than 30 degrees on the side of the dominant wind direction in summer, and is perpendicular to or forms an included angle of more than 60 degrees on the side of the dominant wind direction in winter. The Polyline branched or compound street form are flexible. With the cooperation of cascading architectures, the streets can well adapt to different terrains and the prevailing wind directions in summer and winter to form a suitable microclimate.Synergy and integrity are the key points of climate adaptability for the traditional settlement, and also the key to the protection and inheritance of traditional settlements.
Research on Evolution law and driving factors of rural settlements in hilly areas of western Chongqing from the perspective of urban-rural interaction – A case study of Yongchuan District in Chongqing
(Lodz University of Technology Press, 2023) Li Xu; Luo Qiuyi
From the perspective of urban-rural interaction, taking Yongchuan district in hilly area of western Chongqing as an example, the characteristics of urban and rural settlement evolution were quantitatively studied based on land conversion and human-land relationship, and the influencing factors were quantitatively analysed by geographical detector. The research shows that the rural revitalization cannot be only discussed on the basis of countryside, and the development of villages and towns is not only different but also closely related to the urban development. Industrial transformation and integration, road and port construction and related policies and plans are the core driving forces of rural urbanization development in Yongchuan District. Natural resource endowment, location and population migration are the leading factors of development. Under the comprehensive action of these factors, the local reconstruction of urban and rural space constantly takes place, forming the regional spatial pattern of ‘group layout, driven by multiple points; Central agglomeration, periphery expansion; the inner suburbs compact and the outer suburbs shrink’. Different development modes, land use indicators and development strategies should be determined according to different types of urbanization areas, sustainable development and contraction of rural areas, so as to play a better leading role of planning.
