摘要
防灾公园是城市防灾避难场所系统的重要组成部分,为了强化防灾公园的防火功能,有效阻隔火灾蔓延、抵御外火入侵,宜在其周边栽植防火树林带。本文通过对防灾公园中防火树林带的规划设计与防火功能分析,提出了提高其防火功能的主要措施,即形成防火规模、选择防火性能好及辐射热遮蔽率高的树种和适宜的栽植模式并设置水雾喷洒装置,可以有效地提高防火树林带的防火功能。
Disaster prevention park is an important part of the system of urban disaster prevention and shelter and the planting of the fire prevention forest belts is suitable for strengthening the function of disaster prevention, for fire prevention forest belts can obstruct fire spread and resist the intrusion of outside fire source. This paper designs and analyzes the fire prevention forest belts and their function,and puts forward some measures of improving the fire prevention function by choosing species with high obscuring ratio of radiant heat and proper planting patterns and setting water mist spray devices, which can effectively im prove the fire proof performance of fire prevention forest belts.
