摘　　要：针对目前我国城市人防工程空间分布和防护效能定量描述理论不足、工程演化规律把握不到位等问题,引入分形理论,在城市规划视角下探讨城市人防工程系统的分形演变特征,有效填补了目前城市人防工程研究中关于空间分布和防护效能演化方面研究的空白,并取得了较好的结果。结果显示:(1)研究区人防工程空间结构具有分形特征,经历了由集中分布向均衡分布的演变过程;(2)研究区人防工程空间分布和防护效能演化的速度经历了"先快后慢"的过程;(3)研究区人防工程的空间分形结构逐渐简化。In view of the lack of research on the quantitative description of the spatial distribution characteristics of urban civil air defense projects in China and the inadequate grasp of the law of engineering evolution,the fractal theory is introduced to discuss the fractal evolution characteristics of urban civil air defense engineering system from the perspective of urban planning.which have effectively filled the gaps in the current research on the evolution of spatial distribution characteristics in the current urban civil air defense engineering research,and achieved good results.The results show that:(1)in the study area,the space structure of the civil air defense engineering has fractal characteristics and has experienced an evolution process from concentrated distribution to a balanced distribution;(2)the evolution speed of the space distribution characteristics of the air defense engineering in the study area has undergone a process of"first fast and then slow";(3)the spatial fractal structure of the civil air defense engineering in the study area is gradually simplified.
