Abstract:

In order to establish a meteorological disaster risk evaluation index system, establish the meteorological disaster risk zoning map, the meteorological disaster risk zoning, in the Huixian, northern Henan 1961-2009, meteorological data and the 1961-2009 geological hazards data, the use of meteorological materials, methods and evaluation, from 4 areas of heavy rain, hail, high winds, and geological hazards, hazard analysis, and comprehensive consideration of the hazard, disaster, environmental hazard bearing body. The results showed that the mountainous area of northern Henan heavy rain, hail, the probability of geological disasters was greater than the plains, the opposite gale probability, the occurrence probability of the plains strong winds above the hills and mountains, which provided for local defense meteorological disasters, technological support and theoretical basis.
