摘　　要：京津冀山区受地理条件限制,在区域城镇发展和灾害防控等方面问题突出。从山地城镇扩张与生态约束的关系出发,明确山地城镇扩张的动力以及城镇化影响下山区典型灾害特征,利用P–S–R模型构建基于山洪灾害防控的京津冀山区生态安全格局,并耦合各城镇扩张压力强度,分析得出生态约束条件下山地城镇扩张的四种模式:生态安全水平较低+低度扩张(包括隆化县等21个城镇);生态安全水平较低+中度扩张(包括迁安市等21个城镇);生态安全水平一般+高度扩张(包括蓟州区等11个城镇);生态安全水平较高+低度扩张(包括张北县等14个城镇)。由此通过生态导向的可持续城镇化发展战略与国土空间规划下的区域生态网络建设,有针对性地提出山地城镇的韧性安全发展路径,以有效缓减山洪灾害的风险性与山地城镇扩张的生态胁迫性。Beijing-Tianjin-Hebei Mountainous Area is limited by geographical conditions,and has prominent problems in regional towns development and disaster prevention and control.Starting from the relationship between mountain towns expansion and ecological constraints,this paper clarified the driving force of mountain towns expansion and the typical disaster characteristics of mountainous area under the influence of urbanization.This paper constructed the ecological security pattern of BeijingTianjin-Hebei mountainous area with the P-S-R model based on the prevention and control of mountain torrent disasters.Coupling the expansion pressure strength of each town,four types of expansion patterns of mountain towns under ecological constraints were obtained:Low expansion+low ecological security level,moderate expansion+low ecological security level,high expansion+average ecological security level,low expansion+high ecological security level.Therefore,through the ecooriented sustainable urbanization development strategy and the construction of regional ecological network under national land use and spatial plan,resilient safety development paths of mountain towns were proposed,so as to effectively reduce the risk of mountain torrent disasters and ecological stress of mountain towns expansion.
