EFFECTIVENESS EVALUATION ON METEOROLOGICAL EARLY WARNING OF REGIONAL GEOLOGICAL HAZARDS

The meteorological early warning of geo-hazards has worked for eight years since 2003.The China Institute of Geo-Environmental Monitoring has gained 1281 early warning products.Based on the former products and accuracy methods,this paper establishes an integrated evaluation system for the effectiveness of geological hazard early warning in China.The warning has three elements including early warning time,space and magnitude.Three models are established.The accuracies of geo-hazards early warning in the July of 2008 and the July of 2009 are 16.57% and 24.51%,respectively.These results are just the same as the fact nowadays or in the near future.The integrated evaluation system model includes the time,space,and magnitude of geological hazard early warning effectiveness.This model introduced in this paper is feasible and practicable,which accords with the current level of national and provincial.Therefore it can be applicable to evaluating the level of geo-hazard early warning.
