随着城市化进程加快,城市生态环境特别是热环境越来越受到人们的重视。城市建成区的持续扩张以及绿地的不断减少,加上人为释热增多,明显地改变着城市局部热环境,并产生了可能危害人体健康、影响气象气候、加重能源负担等的“热岛”效应。从城市生态结构区划角度出发,本文提出通过划分生态功能区及生态廊道、设定各区控制指引、构筑生态结构格局,从而缓和城市热环境的一些建设性对策。
With the acceleration of urbanization, urban ecological environment, especially hot environment, has drawn more and more attention. The continuous expansion of urban built-up areas and the continuous reduction of green spaces, coupled with the increase of man-made heat release, have obviously changed the local thermal environment in cities and created “heat islands” that may endanger human health, weather and climate, and increase the energy burden. effect. From the perspective of the zoning of urban ecological structure, this paper proposes some constructive measures to ease the urban thermal environment through the division of ecological function zones and ecological corridors, setting the control guidelines for each district and building the ecological structure pattern.
