摘要
选取长沙市不同植被覆盖度的3个小区,分析植被覆盖度对居民区环境温度的影响与两者间的定量关系。结果表明:(1)植被覆盖度与周边温度之间存在明显的负相关关系,且不同居民区的树冠遮蔽处、阳光直射处、构筑物阴影处也存在类似关系;(2)当居民区植被覆盖度超过40.22%时,植被调节能力有所下降;(3)秋季长沙市居民区内植被覆盖度每增加10%,温度调节能力约0.2℃,植被对居民区内高温、低温均有调控作用。
In order to analyze the influences of vegetation coverage on the ambient temperature of residential communities and the quantita tive relationships between them,three communities with different vegetation coverage in Changsha City were selected.The results showed that:(1)There was a significant negative correlation between vegetation coverage and ambient temperature,and similar relationships existed at canopy shelter,direct sunlight and shadows of structures in different residential areas as well.(2)When the vegetation coverage of residential areas ex ceeded 40.22%,the regulation capacity of vegetation decreased.(3)In autumn,when the coverage in the residential area was increased by10%,the temperature regulation ability was about 0.2℃,whereby the vegetation had a considerable regulating effect on high temperature and low temperature in the residential areas.
