摘要

对基于个人风险的土地利用规划进行研究,确定方法的框架和程序,并应用于某拟建液化天然气储备库周边的土地利用与布局调整。对拟建天然气储备库可能发生的事故,选取蒸气云爆炸及沸腾液体扩展蒸气爆炸进行讨论。在确定事故发生概率及事故后果的基础上,对拟建液化天然气储备库的个人风险进行计算。借鉴英国土地利用规划中个人风险的可接受标准,在液化天然气储备库周围划分三个风险区域,根据各区域的功能规定及储备库周围土地利用现状,对储备库周围的土地利用进行规划与调整。结果表明,液化天然气储备库附近有两处居民区、一个工厂需要搬迁。基于个人风险的土地利用规划方法在合理确定重大 工程选址及周边建筑与设施的布局上是行之有效的方法。
