| Abstract: | This paper describes studies on the integrated risk assessment and zoning of meteorological disaster in Heilongjiang Province, in northeastern China, by using information-diffusion theory and cluster method with 35 years of summer temperature and precipitation data from 74 meteorological stations from 1971 through 2005. The information-diffusion theory has been used extensively in risk assessment, yet almost no one has done research about risk assessment by information-diffusion theory based on meteorological disaster standards. Some research results are as follows: the risk probability of low temperature and cold damage in the northern region is higher than that in the southern region; the risk probability of general low temperature and cold damage in the southwestern region is the highest; the risk probability of serious low temperature and cold damage in the northern region is the highest, followed by the central and southeast region; the high-risk region of arid disaster in Heilongjiang Province was primarily located in the southwestern, central, and southern parts of the province; the high-intensity arid disaster was located in the southeastern region; the high-risk region of flood in Heilongjiang Province was primarily located from the southwest and then across the central part to the western part of Heilongjiang Province; the high-intensity flood disasters were located in almost every part of Heilongjiang Province. We can conclude from the integrated meteorological disaster risk zoning that the high-risk region of meteorological disaster is primarily located in the southern and northern part of the province, the moderate-risk region is distributed in the central southern region and western region, the low-risk region is located in the eastern part, and the light-risk region is located in the central western part of Heilongjiang Province. |
