山区城镇泥石流减灾决策支持系统是山区城镇泥石流减灾的重要手段之一。该系统由基础数据库、泥石流模型分析和泥石流减灾决策应用三大模块构成 ,其主要功能有降水、泥石流地声和运动监测及信息实时发送和接收、泥石流预报、泥石流危险范围预测与灾情预估、泥石流警报和临灾预案制定。其工作流程为 :降水监测仪将降水信息无线发送到控制中心主机 ,主机对降水信息处理后发送给泥石流预报模型进行泥石流预报 ,并利用泥石流危险性分区模型进行危险范围预测 ,同时进行灾情预估 ;泥石流地声监测仪将地声信号发送给主机 ,主机检测到泥石流地声后发出泥石流警报 ;泥石流运动监测仪将运动信息发送给主机 ,主机根据泥石流运动要素进行危险范围划定和灾情预估 ,最后制定临灾预案。
Mountainous area debris flow disaster reduction decision-making support system is one of the important means to reduce the landslide hazard in the urban area. The system consists of three modules: basic database, debris flow model analysis and debris flow disaster reduction decision-making. The main functions of the system are precipitation, debris flow and motion monitoring, information real-time sending and receiving, debris flow forecasting, debris flow hazard prediction and disaster prediction, Debris flow warning and disaster preparedness plan. The workflow is as follows: the precipitation monitor wirelessly sends the precipitation information to the host of the control center, and the host computer processes the precipitation information to send it to the debris flow forecasting model for debris flow forecasting, and then uses the debris flow hazard zoning model to predict the danger range, Earth’s surface acoustic monitor sends the ground acoustic signal to the host computer, and the host computer sends a debris flow alarm when the host detects the earth’s muddy noise; the debris flow motion monitor sends the motion information to the host computer, and the host computer delineates the dangerous area and estimates the disaster according to the debris flow movement element Finally, prepare a disaster plan.
