Tourism Type Town Built Environment Of Micro Climate Research

Along with the advancement of urbanization development in our country,under the huge push of market economy,urbanization and rural residential construction makes the urban built environment become more and more attention.Tourist type towns construction is driving the development of the third industry the backbone of content, towns within the built environment of micro climate is directly related to people’s life and production, this paper has carried on the on-the-spot investigation and measurement,and through the numerical simulation software to type tourist towns built environment microclimate simulation and verification,finally summarizes the micro climate strategy of village environment.Type tourism towns built environment of the micro climate test content including towards street interface and street towards the streets, streets, green plant and form on measured the yard, the built environment, building envelopes in green plants and water test. Agricultural village in chengdu PI county was measured during the period, the author of street geometry, green plant scale and underlying surface topography has carried on the system of surveying and mapping, for the experimental study and numerical simulation provides an important support.towns built environment to as an example of numerical simulation of micro climate, through the numerical simulation software ENVI-met to the measured location selected area are simulated, the numerical simulation value and the measured values, and calibration. Full consideration in the simulation of the atmospheric turbulence, the soil thermal properties, greening and air evaporation, transpiration, and sensible heat coupling, such as using mathematical programming software within the parameter, the calculation of its physical property and the micro climate more reliable simulation analysis. At the same time, the software comes with greening plant species, underlying surface structure and water form the sensitivity analysis, obtained in hot and humid climate environment simulation, the software of the simulation accuracy, the best type of boundary condition, the vertical grid form and etc.
