Study On The Spatial Model Of Microclimate Effect Of Multi-type Mountain Caves In Suzhou Traditional Private Gardens

With the rapid development of urbanization in China,the environment has deteriorated,and the comfort of people's living environment has dropped drastically.There is an increasing demand for garden comfort.As an indispensable part of the garden,the mountain cavern is of vital importance in the design of the garden climate.Studying the influence of mountain caverns on garden microclimate has increasingly become a topic that cannot be ignored in the field of landscape architecture.In this paper,the traditional cave garden caverns in Suzhou are taken as research objects,and the caverns are divided into different types by the design factors that influence the climatic effects of the caverns.The software simulation and site measurement method were used to analyze the microclimate effects of different types of mountain caverns in winter and summer.The effects of different types of caverns on microclimate effects were derived and the spatial patterns of different types of caverns were analyzed.Specifically carry out the following work:(1)Classification of mountain caverns based on climate design.Firstly,the small-climate effect of the mountain cavern is demonstrated,and then the purpose and method of the classification are proposed.On this basis,the existing caverns in Suzhou garden were investigated and a variety of classification methods were compared,and then the classification of mountain caverns based on climate design was proposed.Finally,the typical caverns of gardens were selected.(2)Simulation software verification and typical weather day selection.Taking the typical representative of the existing mountain view garden in Suzhou as an example,the model software verification of the simulation software NVI-MET was carried out.Select a summer day to conduct a test on Huanxiu Mountain Villa,simulate the dailymeteorological data as the initial data,and compare the measured data with the simulated data to determine the accuracy of the ENVI-MET simulation.Based on the evaluation of Suzhou comfort,the typical daily meteorological data of the extreme summer and summer seasons is selected as the basis for the following simulation analysis.(3)Simulation analysis of winter and summer microclimate effects of different mountain types ENVI-MET.Based on the above verification and simulation day selection,combined with the previous classification method,the simulation analysis of different types of mountain winter and summer microclimate effects.The specific method is as follows: the second level index of mountain classification,the position,size,orientation and plant coverage rate of the mountain are studied by variables,and the characteristics of microclimate effects in winter and summer under different variables are explored.(4)The verification of microclimate effects of different types of caverns.On the basis of the previous simulation,the typical Suzhou garden mountain caverns selected in the previous section were tested and verified.Verify the theoretical analysis of the previous text and the correctness of the simulation.(5)Derivation of spatial model of microclimate effect of different mountain cavern types.Based on the theoretical analysis,computer simulation and actual measurement of the microclimate effects of different types of caverns,the spatial patterns of microclimate effects of different cavern types are deduced.
