摘要

为研究湿热地区街区尺度地表形态特征对城市热湿环境的影响

基于局地气候分区的分类方法

在湿热地区广州市选取了7个典型街区并对其进行地表形态特征的参数化表达; 采用实测与ENVI-met模拟相结合的方法

分析了不同街区地表形态特征条件下的热湿环境参数时空分布特征。结果表明

具有高层密集建筑群的街区内呈现出较低的空气温度

而紧凑低层建筑区呈现出高温低湿的热湿环境

开敞空间的街区内空气温度与相对湿度分布更均衡

空间差异性较小。此外

基于实测数据对ENVI-met软件模拟湿热地区街区热湿环境的结果精度进行了验证

结果表明ENVI-met整体上可以较好地预测湿热地区不同街区内的热湿环境特征

但对于紧凑低层建筑区的模拟精度偏低。

Abstract

In order to study the influence of block-scale surface morphological characteristics on the urban thermal and humid environment

seven study typical neighborhoods in Guangzhou are selected based on the classification method of local climate zone and the surface morphological characteristics of them parametrically expressed. And field measurement and ENVI-met simulation are used to analyze the spatial and temporal distribution characteristics of thermal and humid parameters under different block-scale surface morphological characteristics. The results show that the neighborhoods with compact high-rise buildings present lower air temperature

while compact low-rise district presents a high temperature and low humidity thermal and humid environment. Besides

the neighborhoods with open space have more balanced air temperature and relative humidity distribution with less spatial variability. In addition

the accuracy of the results of ENVI-met software simulating the thermal and humid environment in the neighborhoods of hot-humid regions is verified based on the field measured data

and the results show that ENVI-met can predict the characteristics of thermal and humid environment in different neighborhoods of hot-humid regions better overall

but the simulation accuracy for compact low-rise districts is low.
