嶺南地區(qū)郊野公園游客活動(dòng)區(qū)植物遮蔭效果研究
[Abstract]:With the development of urban construction, the earth is getting warmer, and the influence of solar radiation on people's life is becoming more and more intense. In the architectural design, sunshade is often used as the main means to resist solar radiation. In the developed countries of Europe and America, architects also pay more attention to the design of sunshade. But in the landscape design, the landscape architect to the landscape design domain plant shading design research compared with the architectural field shade research appears to be a little less. Plant shading can not only block some solar radiation and reduce atmospheric temperature in landscape design, but also improve landscape microclimate and create suitable landscape. Through the investigation of the tourist activity area in Lingnan country Park, it is found that the measured temperature is worse than that announced by the weather station, and the design of plant shade should be taken into account. In this paper, the effect of plant shading in the tourist activity area of Lingnan country Park was explored by combining the actual survey and ENVI-met software simulation. Firstly, based on the analysis of the geographical and climatic conditions in Lingnan region, this paper studies the effects of plant shading in the tourist area of Lingnan country park, such as landscape design, evaluation index of plant shading effect in Lingnan country park. The research methods of outdoor thermal environment and thermal comfort are analyzed and summarized. Then, the field survey and data analysis on the tourist activity area of country park representative case in Lingnan area are carried out. According to the investigation and data collation, the present situation is summarized which need to consider shading design, including tourist activity center, entrance area, management office and barbecue area, etc., which is the main research object of this paper. Based on the survey data, the effect of shading and cooling in country parks in Lingnan area was analyzed, and the common greening trees in country parks in Lingnan area were analyzed. Then, the common greening shading trees in Lingnan country Park were selected, and the parametric modeling experiment was carried out with different crown shape, crown width and leaf area, combined with rhino software and grassshoper plug-in. The solar radiation transmittance under different leaf area indices was analyzed, and the requirements of leaf area index for Arbor trees under good shading effect were explored, and suggestions for tree shade selection in Lingnan country Park were put forward. Finally, based on the analysis of theoretical basis and practical investigation, the shading effect of Lingnan country park tourist activity area is analyzed. Then it is extended to a practical project of scenic area planning and design. The site model of the entrance area with more tourists' activities is established by using ENVI-met simulation software and the shading situation after the site is completed is analyzed. This paper is a part of a project supported by the National Natural Science Foundation of China Youth Science Foundation (No:50908087), "Regional study on the Planning and Design of country Parks in Subtropical regions-taking the Pearl River Delta region as an example". The purpose of this paper is to explore the effect of plant shading in the tourist activity area of country parks in Lingnan area, and to provide guidance and reference for the study and design of shading system in country parks.
