A Study on Disastrous Law of Flood in Hubei Province

Abstract:

Using the daily precipitation and disaster census data of 76 metrological stations in Hubei province from 1960 to 2005, the authors studied the temporal-spatial distributions and disastrous laws of flood. The results show that the frequent occurrence area of flood mainly occurred along the river, with the high value center in Tongshan, Chibi and Chongyang. The average annual occurrences of flood disaster showed three different tendency periods from 1960 to 2005, with a decrease of stations of flood after 1996. The flood disaster mainly concentrated in summer. The overall variation trend of flood disaster-causing intensity is quasi periodic oscillation. Both of the damaged areas of agriculture crops and agricultural economic losses reached maximum values in the 1990s, and with a correlation coefficient of 0.80 between the two variables. There was good relationship between the flood-affected population and direct economic losses. The increasing speed of direct economic losses was accelerated with the growth of flood-affected population, while the abilities to prevent flood disaster were also strengthened.
