山地城市绿地布局的防灾效能评价——以湖南省湘西州保靖县城市绿地为例
|
摘要
山地城市是一种生态敏感性较高的人居环境类型,面临多种自然灾害的威胁,建立完善有效的城市防灾系统是非常重要的。城市绿地作为城市防灾系统构成的重要环节,其空间布局需要在客观评价防灾效能的基础上进行规划。以湖南省湘西州保靖县城市绿地为例,通过对灾前城市灾害易发区的隔离性、灾时人群避灾救援的接纳性、灾后灾民临时安置的支持性3项内容的评价,探讨山地城市绿地布局防灾效能评价的基本方法,以期为山地城市防灾系统的科学建构提供行之有效的技术支撑。
Mountain city is a kind of human settlements with higher eco-sensitivity,and is faced with the threat of natural disasters.So the importance of establishing effective urban disaster prevention system is self-evident.Urban green space constitutes an important part of urban disaster prevention system,and planning of its spatial distribution must be made based on objective evaluation of its disaster prevention performance.Taking the urban green space of Baojing County,Xiangxi,Hunan,for example,through evaluating the isolation of urban disaster-prone areas,the crowd's admission of avoiding calamity,the support of temporary settlements of disaster victims,the basic approach of evaluating disaster prevention performance of the layout of green space in mountain city is explored,with a view to provide effective and technical support for construction of disaster prevention system in these area.
