【摘要】 以保定市龙潭公园为研究对象,在现场实测和ENVI-met软件数值模拟的基础上,立足于城市公园绿地内部空间热舒适度研究,深入探讨城市公园绿地空间布局和构成要素对城市热环境的调节作用,尝试总结并提出城市公园绿地热舒适度的改善策略,以期为类似尺度公园绿地的规划设计与优化改造提供一定的参考和依据。结果表明:(1)软件模拟结果与实测结果的校验表明,该模型能够较好的反映出模拟区域的微气候变化情况,运用该软件有助于对后续获得优化方案以及策略的可信性进行评估和判断。(2)运用数值模拟得到的直观数据,总结城市公园绿地景观要素(植物、铺装、地形、水体)等与小气候要素的量化关系,同时建立不同改善预案下的微气候模拟分析研究,对比分析城市公园绿地热舒适度改善效果,最终得到城市公园绿地热舒适度改善策略。更多还原

【Abstract】 We took Longtan Park in Baoding as the research object, based on field measurements and numerical simulation of ENVI-met software to research on the thermal comfort of the internal space of urban park green space, to discuss the spatial layout and constituent elements of urban park green space on the thermal environment of the city regulating effects, and to summarize and propose strategies for improving the thermal comfort of green spaces in urban parks, with a view to providing a certain reference and basis for the planning, design, and optimization of green spaces in similar parks. The results show that(1) The verification of the software simulation results with the measured results shows that the model can better reflect the microclimate change in the simulated area. The use of the software can help to obtain the credibility of subsequent optimization schemes and strategies. We make assessments and judgments.(2) Using the intuitive data obtained from numerical simulation, we summarize the quantitative relationship between the green park landscape elements(plants, paving, terrain, and water bodies) and microclimate elements, and establish microclimate simulation analysis studies under different improvement plans, and compare and analyze the thermal comfort improvement effect of the urban park green ground. Finally the strategy to improve the thermal comfort of the green space of the urban park is obtained.更多还原
