Investigation And Research On Microclimate And Comfort Of Dalian Labor Park

With the rapid development of urban economic construction,people's requirements for the quality of life are gradually increasing.The social,economic and ecological benefits of urban parks will have a direct impact on the quality of life of citizens,so it is very important whether the planning and design of the park is reasonable.Dalian Labor Park has a long history,a special location and a large area.It is one of the representative parks in Dalian.Located in the center of Dalian,the park is the most scarce area of urban land resources,but it has not been fully and effectively used.In the field investigation,it was found that the distribution of the number of tourists in each area in the park is extremely unbalanced,and the microclimate and comfort are one of the important factors that affect the movement and distribution of tourists.Therefore,in this article,the microclimate of Dalian Labor Park Investigate and research on comfort level,hoping to improve the utilization rate and use evaluation of the park.This paper takes Dalian Labor Park as the research area and takes a one-year cycle to collect the air temperature,relative humidity and wind speed data of the four seasons in the park,and calculate the park comfort.Analyze the microclimate elements and comfort of the park from the perspective of time and space;collect the structural feature information of park users and their subjective evaluation of comfort through questionnaire surveys,and use SPSS software to conduct correlation analysis of subjective and objective comfort evaluation results.Measure the air temperature,relative humidity,and wind speed of different types of landscape elements in summer and winter on the spot,calculate comfort,and analyze the impact of various landscape elements on comfort.Draw conclusions based on the above research:The overall four-season comfort index evaluation of the park,spring comfort level: "comfortable,feel comfortable";summer comfort level: "hot,most people feel uncomfortable";autumn comfort level: "comfortable,feel comfortable";winter comfort level: "Cold and uncomfortable".The order of the comfort level of the four seasons in the park: autumn> spring>summer> winter.Although there are differences in the subjective and objective evaluation of park comfort,the overall relationship is significant.The four seasons in the park have different effects on the comfort of microclimate elements: relative humidity > air temperature > wind speed in spring;relative humidity > air temperature > wind speed in summer;air temperature > wind speed > relative humidity in autumn;wind speed > air temperature > relative humidity in winter.In summer,the comfort level of different ground paving: grass > masonry paving > asphalt road;the comfort level of different plant types: arbor forest > grass > bamboo forest > hedge;the comfort level of different water bodies: middle pool > waterfall > stream > small pool > large pool;comfort level of different structures:corridor(no wall)>water pavilion>pavilion>corridor(with wall).In winter,the comfort level of different ground paving:grassland>masonry paving>asphalt road;microclimate comfort level of different plant types:grassland>hedgerow>bamboo forest>arbor forest;different water body comfort level:small pool>large pool>stream>Waterfall>Middle pool;comfort level of different structures:water pavilion>pavilion>corridor(with walls)>corridor(without walls).According to the degree of influence of microclimate elements on comfort and the influence of various landscape elements on comfort,shading design is one of the most effective means when improving the effect of comfort through landscape design.Combining the above research content and conclusions,suggestions are made to improve the effect of landscape management and maintenance of park facilities and the improvement of comfort,as well as the reasonable utilization of park tours in each season.
