从人体呼吸健康的角度,提出健康风速区的概念,并
计算相应的风速范围。以北京地区多层板式小区为研究对象,
利用调研数据构建植物模型,逐项模拟植物群落的形态特征(群
落高度、群落宽度)和结构特征(群落叶面积指数、群落冠下高
度)对居住区健康风速区面积的影响。结果表明:居住区户外风
环境可以通过调节植物群落提升健康性。在形态特征方面,健
康风速区面积随着群落高度和群落宽度的增加而增加,高大乔
木多、占地面积大的植物群落可显著提升风环境的健康性;在
结构特征方面,群落叶面积指数和群落冠下高度与健康风速区
面积之间呈现先递增、后递减的非线性函数关系。群落宽度对
风环境健康性的影响程度最大。以高大乔木为主、冠层疏松或
种植分散的植物群落更有利于改善风环境的健康性。在北京多
层板式小区的布局下,增加绿化面积和高大乔木的数量、加强
管理养护、维持植物群落疏密程度对于创造健康的户外风环境
具有重要意义 |

Research on the Influence of Plant CommunityCharacteristics on the Health of Residential WindEnvironment: Taking Multi-storey Slab ResidentialArea in Beijing as an Example |
PENG Lei,YIN Hao |
Abstract: |
From the perspective of human respiratory health, the
concept of healthy wind area was proposed and its wind speed
range was calculated. Taking multi-storey slab residential areas in
Beijing as research objects, this study builds plant models based
on survey data, and simulates the influence of morphological
characteristics (height and width) and structural characteristics
(LAI and height under canopy) of plant community on the healthy
wind area in residential areas. The result reveals that the wind
environment of residential areas can be improved by adjusting plant
communities. In terms of morphological characteristics, healthy
wind area increases with height and width. Plant communities with
more tall trees and larger covering area can significantly improve
the health of wind environment. As for structural characteristics,
there comes a curve regression relationship that increases first and
then decreases. Among them, width has the greatest influence on the
health of wind environment. Plant communities with more tall trees,
sparser canopy or scattered planting location are more conducive
to strengthen the health of wind environment. Under the layout of
multi-storey slab residential areas in Beijing, increasing the area of
green space and number of tall trees and enhancing management to
maintain the density of plant communities make sense to create a
healthy outdoor wind environment. |
