Theoretical And Practical Research On Human Settlements Constructive System Of The Loess Plateau

Sustainable development, the guideline of human beings' existence and development in 21 century, has penetrated into all fields and industries, including architecture. In connection with urbanization of human settlements, problems, such as environment pollution, energy and resources crisis, living environment improvement and so on, caused by social and economical development and our national conditions, it has become an urgent and critical issue how to coordinate environment with development, globalization with regional problems and maintain sustainable development of building human settlements.Urban and rural areas have undergone irreparable damage in the process of large-scale construction. The traditional settlements and homes rooted in the natural and cultural environment are being replaced by the pattern of urban construction. The sustainable development of traditional constructive system is confronted with all kinds of difficulties. From the perspective of regional constructive system, the research aims at finding out how to uncover and sort the regional constructive experience, rich in ecological value and wisdom, then to combine the experience with the current scientific methods and technological achievements to turn it into scientific constructive system and method of regional human settlements, and finally to make the sustainable development of the regional traditional architecture reborn.In view of the human settlements conditions and problems in our country, this paper, drawing on the experience of oversea regional human settlements theories and practices, puts forward the concept and connotation of the regional constructive system.Second, inspired by knowledge in the following scientific fields: Archtypos theory from literary criticism, the law that gene acts on biological traits in biological gene, system theory and system engineering method from control theory, principles of ecology and its wisdom, and form conversion in overall structure from Topology geometry, the research places the regional constructive system in a dynamic network involving cultural, economical and natural elements, grasps the constitutional relationship of the system structure from all perspectives, discloses the origin, finds a scientific solution, masters the regulation mechanism, morphogenetic mechanism and evolution mechanism of regional gene. Furthermore, the paper builds a neuron BP network index method, based on which the theoretical framework and operation platform for the regional constructive system are formed, and they provide scientific methods and construction guidelines for research on the sustainable development of regional constructive system.Guided by the theoretical framework, the paper selects cave dwelling constructive system on The Loess Plateau to conduct case study. Through analysis of ecological, economical, cultural and social environment of The Loess Plateau, diagnosis, identification, restructuring and integration of the regional gene of cave dwelling constructive system and analysis and grasp of its systematic rules, the paper constructs a regional gene pool of cave dwelling and regulates the evolution process towards the goal of sustainable development.Finally, the paper applies the theories and principles of constructive system to the pattern design of green cave dwelling constructive system and constructs cave dwelling yards, basic living units and its settlements. Moreover, the paper provides countermeasures for all-level pattern design and diverse topological groups of form conversion, designs and provides templates for professionals and residents, thus can be beneficial to the benign development of cave dwelling constructive system. In order to verify the feasibility of the theoretical research, the paper conducts an empirical study on construction of Zaoyuan village, a demonstration of green settlements, hoping to bring experience and inspiration to research on green settlements in other regions.
