Development of Three Dimensional Numerical Plant Model including relazation effects on outdoor thermal environment comprehensively

(1)建立了考虑室外热环境松弛效应的三维植物模型原型，包括防风效应、遮阳效应和降温效应。(2)上述植物模型的物理参数，如植物冠层的几何形状，叶面积指数或阻力系数，是通过对典型的路边树木的现场试验结果确定的。(3)并将上述规划模式应用于室外空间规划，进行了多个案例研究。在此基础上，研究了行道树对室外热环境的缓解作用。(4)利用田间试验结果对所建立的植物模型进行了验证研究。这一检验结果反映了该模型的进一步改进。(5)利用实例研究的结果，对植树造林的最佳安排进行了研究。然后确定种植设计文件。

(1) The proto-type of three dimensional plant model including relaxation effects on outdoor thermal environment, such as wind-reduction effect, solar shading effect or temperature decrease effect, was developed.(2) The physical parameters of the above plant model such as plant canopy geometry, leaf area index or drag coefficient, wrere determined through the field experiment results for representative roadside trees.(3) Several case studies that the plan model developed above was applied to outdoor space was conducted. Then the relaxation effect of roadside trees on outdoor thermal environment was examined.(4) The validation study of the plant model developed here was conducted using the results of field experiment. This examination results was reflected for fouther improvement of this model.(5) Optimum arrangement of planting trees were examined using the results of case studies. Then planting design documents were fixed.
