“长治”工程滑坡泥石流预警信息系统的构建

Information system construction of early warning for landslide in "the Yangtze River Management Project"

长江上游是我国著名的滑坡危险区、泥石流易发区,滑坡、泥石流具有突发性和瞬时性的特征,危害巨大。长江上游水土保持重点防治区滑坡泥石流监测预警系统(简称预警系统)监控面积达11.34万km2,是全国覆盖面最广、规模最大的山地灾害监控网络,预警系统对于有效降低长江上游水土保持重点防治区滑坡泥石流灾害程度起到积极作用。为提高预警系统管理水平,达到科学监测、预警及时、规范管理,实现监测数据和成果的远程准确上报、快速查询、分类统计,对长江上游滑坡泥石流灾害进行自动化和信息化处理,为科学决策提供依据。

The upstream area of the Yangtze River is a typical dangerous landslide and mud-rock flow prone area in China.The landslide and mud-rock flow have characteristics of suddenness and instantaneity with great harm.Landslide and Mud-rock Monitoring and Pre-alarm System for Main Prevention and Control Area of Soil and Water Loss in the Upstream Area of the Yangtze River covers an area of 113.4 thousand km2,where is the most widely area-covered and largest mountainous disaster monitoring network in China.The pre-alarm system plays an active role in effective reduction of landslide and mud-rock flow in the area.In order to improve management level of the pre-alarm system to realize scientific monitoring,timely alarm and standardized management,the Information Management System of Landslide and Mud-rock in the Upper Yangtze for the pre-alarm system is applied to realize accurate remote report of monitoring data,quick query,classified statistics,automatic information processing,so as to provide scientific basis for decision-making.
