The Ecological Adaptability Study For Chongqing Rural Human Settlements Plan

With the in-depth development of ecological protection concept in China,the ecological environment protection within current urban areas has made great progress.However,the rural human settlement environment is facing more ecological contradiction affected by the contradiction between urban and rural duality system,the large base figure of the rural population and construction land,the urban expansion and urban living habits,which has become the bottleneck of the overall ecological civilization construction of the country.In western provinces,mountainous areas are more sensitive and fragile in ecological environment because of the relatively backward economic development stage.Moreover,the idea of adaptive planning as well as lag of construction method and technical method require urgent implementation of ecological adaptability study on the rural human settlement environmental planning in Chongqing.On the basis of combing the ecological planning and construction of the rural human settlement environment at home and abroad,this thesis establishes the ecological adaptability theory of the rural human settlement environmental planning in Chongqing at the theoretical level,and discusses the planning path of ecological adaptability of rural human settlement environment in Chongqing at the empirical level.Firstly,the thesis combs the traditional ecological concept and historical law of the rural human settlement to analyze the basic theory of ecological adaptability of rural human settlement environmental planning,and draws on the scientific spatial hierarchy concept of human settlement environment to divide the ecological adaptability of rural environmental planning in Chongqing into three levels of “macro-village domain,meso--village community,micro-farm house environment”.Furthermore,it puts forward the ecological adaptive control path at the macro-village domain level,the ecological adaptive promotion path at the meso-village community level and the ecological adaptability optimization path at the micro-farm house environment level.The main contents of the thesis consist of six parts.(1)Along with the idea of investigation,discovery and analysis of problems,this thesis takes the Chongqing area as an example to carry out an investigate on the related problems during the construction of rural human settlement environment planning.From the macro,meso and micro-level points of view,it puts forward three core problems that the sound ecological network structure under the native state of village community requires control by means of planning measures,the rural human settlement planning structure needs further optimization at the ecological factor level,and the ecological construction activities of rural farm house environment are still at a low level and remain to be improved.(2)The establishment of theoretical framework of ecological adaptability of rural human settlement environmental planning in Chongqing mainly includes historical law cognition,modern basic theory cognition,ecological adaptive mechanism analysis and content interpretation of rural planning,and it puts forward the planning paths corresponding to three levels.Firstly,it summarizes the time development law and ecological construction wisdom of ecological adaptability of rural human settlement environment.Secondly,it studies the basic theory of ecological adaptability from the theories of human settlement environment science and ecological adaptability with overall guidance significance to the theories of landscape ecology,ecological adaptability planning and suitable technology at different spatial levels.Thirdly,it analyzes the ecological adaptability mechanism such as endogenous mechanism,external driving mechanism,differentiation mechanism and multi-scale guidance mechanism.Finally,it proposes the composition of ecological adaptability of rural human settlement environmental planning in Chongqing,including the objectives,principles and elements of planning ecological adaptability,and the planning path frame of “pattern control — structure optimization — quality promotion”.(3)At the macro-village domain level,this thesis takes pattern control as the orientation to study the landscape ecological pattern control path of the village domain in Chongqing.Firstly,it studies the connotation constitute of ecological adaptability of village domain,such as landscape ecological resource investigation,landscape ecological pattern and ecological sensitivity analysis,function analysis and division of ecological service,suitability analysis and evaluation of village domain construction,etc.;Secondly,it puts forward the application path of ecological adaptability in the overall planning of village domain,such as village ecological feature and positioning study,ecological space planning of village domain landscape,spatial control planning of village domain,industrial development and spatial layout planning of village domain.Finally,it carries out the empirical study in combination with the actual cases in Chongqing.(4)At the meso-village community level,this thesis takes structure optimization as the orientation to study the spatial structure optimization path of the rural human settlement environment in Chongqing.Aiming at various factors of spatial structure level of village community,it makes adjustment at the path level so as to achieve the ecological goals of effectively saving resources and energy,planned ecologicalization and sustainable development,and relieve the ecological contradiction caused by planning and construction.The optimization path of spatial structure of rural human settlement environment in Chongqing mainly includes four aspects of cluster layout of the human settlement spatial structure,ruralization and ecologicalization of public space,ecological planning of road traffic and nature-friendly treatment of infrastructure.(5)At the micro-farm house environmental level,this thesis takes quality promotion as the orientation to study the ecological quality upgrading path of the rural farm house environment in Chongqing,and concretely sums up four paths of land-saving guidance,energy-saving guidance,material—saving guidance and locality guidance,together with three paths of strategic guidance,index control and rational design.The energy-saving guidance path carries out study from the aspects of energy-saving planning of farm house settlement environment,seasonable energy-saving design of farm house,effective utilization of household renewable energy,etc.The material-saving guidance path includes the economization of construction material of farm house and the modularization of local material of farm house.For locality guidance path,it analyzes two main types of common farm house environment and traditional dwelling environment.(6)The innovative points of the study are mainly reflected in three aspects of ecological adaptability perspective,ecological adaptability thinking framework and ecological adaptability planning path in the rural human settlement environment planning in Chongqing.Firstly,this thesis probes into the ecological adaptability perspective of rural human settlement environmental planning in Chongqing based on communities of different spatial levels through mechanism and factor analysis.Secondly,it establishes the ecological adaptability thinking framework of rural human settlement environmental planning in Chongqing of “3 challenges — 3 levels — 3 paths”.Finally,it combines the thinking framework to put forward the planning path of ecological adaptability of rural human settlement environment in Chongqing,namely macro-village domain,meso-village community and micro-farm house environment.
