Study On The Principle Of Ecological Symbiosis And Collaborative Construction Method Of "Plant-Houses" In Loess Plateau

The opportunities and challenges for rural development coexist in the new period of China.Rural environment and construction are facing the severe challenge of sustainable development.The idea of win-win effect of economic energy saving and health and comfort has become increasingly clear.In the Loess Plateau,the gullies are vertical and horizontal,the rainfall is less and concentrated,the wind and sand are strong,the comprehensive ability of sustainable development is low,and the natural ecological foundation is weak.This study is based on the Loess Plateau area,with the microclimate regulation as the breakthrough point,using the combination of design and technology,focusing on the Ecological Symbiosis Mechanism of plants and dwellings in the Loess Plateau,in order to better play the role of plants in improving microclimate.On the basis of clarifying the quantitative relationship between plant elements and indoor and outdoor thermal environment of residential buildings,this paper explores the ecological symbiosis mode and cooperative construction method of plants and residential buildings suitable for the Loess Plateau.This is not only beneficial to solve the indoor and outdoor environment comfort problems of residential buildings through plant microclimate design,but also provides a reference for improving the space quality of residential houses.It also provides scientific guidance for the planting design of residential houses built in rural landscape planning and the "integration" design of plants and residential buildings.It has practical significance for achieving the sustainable development goal of economic energy saving and health comfort win-win.Based on this,the study is divided into four parts:Firstly,based on the law of regional differentiation of water and heat factors,taking the overall vegetation landscape as a reference,taking the local environmental background as the basis,following the principles of local residential culture and residents' needs,the greening plants of residential buildings in the Loess Plateau were zoned and selected(Chapter II).Through in-depth and detailed field research on different types of courtyards in typical research areas of the Loess Plateau,the planting habits of residential courtyards in the region were summarized and the influencing factors were analyzed.(Chapter III)Secondly,in order to create a comfortable living environment and economic and energy-saving goal,using the combination of field measurement and ENVI-met software,this paper analyzed the changing law of the influence of plants on thermal comfort in the courtyard space,and determined the reasonable layout and planting scale of plants in the courtyard space.Ecotect software is used to quantitatively analyze the shading effect of shading trees on buildings,and to determine the scientific planting and type selection of shading trees in residential building environment,to clarify the function mechanism of plants on dwellings and maximize the ecological co-benefits of plants and dwellings.(Chapter IV)Thirdly,considering the ecological factors to meet the growth needs of plants,the software Skethup is used to simulate the influence of vertical factors on sunshine.According to the changing law of the temperature of houses and the requirement of winter sunshine,the height control requirements of plants planting in the space of houses are obtained.At the same time,the main modes of rainwater collection and utilization in houses are discussed.(Chapter V)Finally,based on the results of simulation analysis,the Ecological Symbiosis Model of plants and dwellings on the Loess Plateau is discussed in combination with factors such as the overall spatial form of villages,the architectural form of dwellings,folk culture and economic and technological level(Chapter 6).Focusing on the optimization of plant layout in residential environment,this paper constructs a cooperative construction system to meet the ecological symbiotic needs of plants and residential buildings,and puts forward a method of "plant-residential" cooperative construction on the Loess Plateau.(Chapter VII)This paper innovatively divides and chooses the greening plants of the residential buildings on the Loess Plateau;simulates and analyses the Ecological Symbiosis Mechanism of plants and residential buildings by using computer software;studies the ecological symbiosis mode of plants and residential buildings on the Loess Plateau;puts forward the optimized layout mode of plants in residential space environment to meet the thermal comfort in summer;and constructs the synergy of plants and residential ecological symbiosis needs.The construction system and the method of "plant-dwelling" co-construction on the Loess Plateau are put forward.It provides a convenient and effective guidance for the design of plant microclimate in the residential environment of the Loess Plateau.It is of practical significance to quantify plant microclimate design by technical means and to effectively play the regulating role of house planting design in residential outdoor environment.It is the perfection of the theoretical system of rural planning and design in the Loess Plateau,and plays a role in promoting the sustainable development of human settlements in rural areas.
