| By means of field investigation,data statistics and analysis,Linpan microclimate evaluation and quantitative analysis of microclimate elements in winter and summer,this paper integrates and puts forward the optimization strategy of Linpan microclimate in Western Sichuan,which provides ecological research support for Rural Revitalization and beautiful rural construction.The main work and conclusions of this study are as follows:(1)I measured and analyzed the microclimate parameter of different living spaces in Linpan of Western Sichuan in winter and summer,and studied the influence of Linpan elements on microclimate qualitatively.We analyzed the influence of Linpan elements on air temperature,relative humidity,solar radiation,wind speed and other microclimate parameters from time and space step by step,and compared the Linpan essentials's function in winter and summer comprehensively.The analysis shows that the microclimate of Linpan is affected by environmental factors such as building layout,tree top interface coverage,tree and grass green quantity,underlying surface material,water area and so on.(2)On the basis of qualitative analysis,combined with Google Earth high-definition satellite images,quantitative factors affecting the microclimatic environment of Linpan were quantified on the scale of 10 m radius and 30 m radius:tree coverage,forest-grass coverage,tree-grass ratio,building density,hard ratio and water ratio.The correlation between each influencing factor and microclimate parameters was analyzed,and the multivariate regression equation of microclimate comfort was constructed.The results show that tree-grass ratio has the strongest ability to change WBGT,and can be used as an important design factor in vegetation elements.Building density is negatively correlated with air relative humidity at the radius of 10 m,but its influence ability decreases with the increase of research scale.The proportion of water body is negatively correlated with temperature at 30 m radius scale,and significantly correlated with relative humidity at both scaleS,Which means that small-scale water body can humidify and large-scale water body can cool down.(3)On the basis of the above research,combined with the reading and collation of literature,the evaluation indexes and standards of winter and summer were determined.WBGT index was used in summer and TS index was used in winter to analyze and evaluate the microclimate comfort of winter and summer respectively.The Linpan measurement points will be very good comfort in summer,but most of them are in a "cold"state before 12:00 in winter,and the comfort level of the house area is almost in the "cold"level during the actual measurement period in winter.In tie planning aad design,measures should be taken to increase the winter temperature of the house area,while maintaining its good characteristics of passive cooling in summer.(4)Combined with the previous research,the paper puts forward the construction strategy based cm the improvement of micro-climate comfort for the layout of courtyard,plant planting,waterscape construction and underlying surfae configuration.Through reasonable spatial layout,suitable water landscape construction,diversified green vegetation collocation,humanized design of hard activity sites and other means of landscape improvement,can greatly enhance the comfort of Linpan microclimate,and provide an effective way to create a good living environment with low energy consumption. |
