Study On Microclimate Of Sichuan Hilly Tourist Attractions

With the continuous improvement of people's life and economic level,outdoor tourism activities are also increasing.Under the obvious background of global climate change,the energy consumption of tourist attractions is also becoming more and more serious and needs to be given some attention.Research on the microclimate in the outer space of the scenic area is conducive to reducing energy consumption,improving human comfort,providing a healthier and safer environment for tourists and residents,and broadening the thinking of energy-efficient building design,which ultimately benefits the sustainable development of the scenic area.The tourism resources in our country are quite rich.Different landscape features and different geographical locations correspond to different climatic features and topographical locations.The research in this paper is limited to tourist attractions in Sichuan hilly areas.1.Four typical regions(Yibin,Leshan,Luzhou and Mianyang)in hilly areas of Sichuan Province were selected.According to the typical year's meteorological data,the four aspects of solar radiation,air temperature,air humidity and wind weather Data,and draw a line chart,and the hilly areas of Sichuan's geographical features and climate characteristics are summarized.2.Firstly,the domestic and foreign microclimate evaluation models are summarized,and then the advantages,disadvantages and applicability of typical microclimate evaluation models are analyzed.Finally,the climate model suitable for this area is selected based on the climatic characteristics of the hilly area in Sichuan Province.In this paper,the simplified outdoor WBGT index is selected to evaluate summer outdoor microclimate of Sichuan hilly tourist attractions and the TS-Givino index method to evaluate winter outdoor microclimate.3.Taking the typical bamboo scenic area of Sichuan Province as the example,the micro-climate of the scenic spot was measured by using the experimental apparatus in summer and winter.The main measured environmental parameters are solar radiation,wind speed,temperature and humidity Summer and winter data comparison.The data of summer and winter are respectively analyzed and evaluated,and the evaluation results of summer andwinter are compared and analyzed.At the same time,tourists and local residents were surveyed and subjectively assessed for their micro-climate comfort,and the subjective and objective evaluation results were compared and analyzed.4.The relationship between microclimate comfort and architectural elements(building shape,building orientation,architectural structure,building materials,building color),green plant,water body and so on in scenic area is analyzed.Based on the actual measurements of microclimate and the geographical features of the hilly region,this paper puts forward the optimization strategies on the three aspects of building site selection,building body design and building external environment design.Regarding the research of tourism comfort,most scholars study the climate and environment from the large-scale scope.Although some scholars have studied the micro-climate with the small-scale tourist attractions as the research object,but less for hilly areas.Based on the geographical and climatic characteristics of the hilly region,this paper presents a microclimate evaluation model suitable for the region.Through the actual measurement and questionnaire survey in summer and winter,the microclimate is comprehensively evaluated from the subjective and objective aspects.The article puts forward the strategy of optimizing the architectural elements and creating a good microclimate.
