Research On Influence Between Scale,Tree Cover And Surrounding Microclimate Of Lin Pan In West Of Sichuan

As typical form of living in West of Sichuan,Lin Pan has a rich landscape and ecological value in the development of thousands of years.However,because of the Incomplete understanding,many unique Lin Pan was severely damaged in the rapid development of the city,in which the traditional local civilization is facing the crisis of destruction.Through the study of Lin Pan,this paper will help us to understand the value of Lin Pan in order to protect and utilize the Lin Pan in west of Sichuan,which can ensure the sustainable development of local landscape.At the same time,it can bring a lot of inspiration for the exploration of the rural settlements in western Sichuan.And It's also important for the study of habitat ecological environment.Based on the collection of area,perimeter,tree cover and microclimate data of 36 Lin Pan in Chengdu,Sichuan Province,we come to the conclusion on influence between scale,perimeter,tree cover and the,humidity,wind speed,light by spatial statistical analysis,correlation analysis and regression analysis,which is a supplement on research of Lin Pan and provide some theoretical guidance for the new rural construction.Through the analysis and comparison of the research data,we found that The Lin Pan can affect the microclimate environment in a certain range in the four seasons.The conclusions are as follows: The temperature cool down in the spring,summer and autumn,but the temperature heat up in winter;The humidity increases in spring,autumn and winter,but reduces in summer.The wind speed and light intensity are reduced in four seasons.In the correlation analysis of the micro-climate of the Lin Pan.it was found that there was no correlation between the area,the circumference,the tree cover and the sphere of influence.It is partly related to the degree of influence.In the spring,the degree of humidification was linearly correlated with tree conver,and the degree of cooling in summer was linearly correlated with circumference,and the degree of decreasing temperature in autumn was correlated with tree coverage,and the largest degree of cooling was in 65%-68% range.The degree of humidification in autumn is also related to circumference,in which the largest degree of humidification is 850m-950 m.The degree of heat preservation in winter was correlated with the circumference and tree coverage.The degree of humidification in winter was linearly correlated with area and tree coverage.On this basis,the comprehensive discovery of the Four seasons,we conclude that when the circumference is bigger than 750 m,tree coverage deviations from 65%-68%,It's good for temperature in summer and winter.And the more tree coverage,the larger area,the better on t influence of the surrounding humidity in winter.Therefore,the 750 m is the lowest limit of the circumference of the Lin Pan,which has a smallest effect on the extreme seasonal environment.At the same time,more than 68% in tree coverage is better for the control of extreme microclimateOn the whole,the relationship between the Lin Pan and the surrounding microclimate provides a good reference for the future planning of new countryside and urban green space,and can guide the design more concretely.
