    摘要:在城市社区2km内尺度上,应用计算流体力学(CFD)空气动力模拟软件,融合绿地生物特征解释式,设置城市近地面层典型气候条件,模拟社区建筑群与绿地之间的局地微气候风温效应场景。模拟实验结果证实,绿地与建筑区域之间的气候效应与其布局方式密切相关,绿地格局的变化会引起区域微气候风温环境的变化。正是由于不同空间格局绿地营造的不同微气候环境,因而不同规划设计方案对生境状况的影响也有所不同。从模拟结果来看,在绿地的不同布局环境中,绿地与建筑区之间微气候的风速大小、风场分布及温度分布都有一定的规律性,其定量关系是可以通过一定的技术方法来确定

    Abstract:This study simulates local micro-climate effects scenarios between community buildings and green space with the aerodynamic simulation CFD software and the fusion of green space biological characteristics explanation type. The simulation area is about 2km, which is the urban community scale. The simulation background environment set by the city near the ground layer typical climatic conditions. The simulation results indicate the micro-climate effect between the green space and building closely related to their regional layout. The changes of green space layout induce regional micro-climate changes. Because different spatial patterns of green space generate different micro-climate environments, the different planning and design scheme has different effect on the condition of the habitat. From the experimental results, in the different layout of green space environment, the micro-climate between green space and building area, the size of wind speed, wind field distribution, and temperature distribution show certain regularity, and the quantitative relationship can be done by a certain technical methods.
