【摘要】 本文介绍了雅安市地质灾害预警预报系统的建设基础、工作流程和2013年汛期运行情况。本系统在地质灾害调查获取的易发性分区图及预警判据体系的基础上,利用WEBGIS平台构建;运行时需要输入区域降雨量监测值和降雨预测值,得出相应的危险性分布情况。本系统2013年汛期运行,对地方地质灾害防灾减灾提供了技术支持。本文结合一次典型的预警实例(2013年7月7日),对预警的效果进行了评价,并指出了系统存在的问题和下一步的工作方向。更多还原

【Abstract】 In this paper,the authors introduced the basis,flowchart of the geohazard warning system of Ya ’an,Sichuan. This system is based on the geohazard susceptibility map and critical rainfall values,which were obtained by geohazard survey and mapping. WEBGIS platform was also used. To run this system,the rainfall monitoring data and rainfall prediction data are required. In the rain season of 2013,this system greatly strengthened the geohazard prevention work of Ya ’an. We take the warning of July 7,2013 as a case,evaluated the consequences of this system,and analyzed some issues in the geohazard warning realm,and put forward several points which should be focused in the future studies.更多还原
