Mountain Torrent Disaster Prevention Early Warning Index System Research In Jiangxi Province

Mountain torrent disaster is refers to the hills region due to precipitation of a disaster, the main factors affecting the climate, rainfall, geographical environment and human activities, etc.Mountain torrent disasters in jiangxi province, affected by the mountain torrent disaster is more serious, mainly for the mountain river floods.Mountain torrent disaster to the people’s life safety and property has brought great threat, to the society, economic development and the construction of a well-off society in an all caused serious influence.Based on mountain flood disasters in jiangxi province, the type, size, distribution and characteristics of the historical data collection, and analyze the causes and characteristics of mountain flood disasters in jiangxi province and jiangxi province mountain torrent disaster prevention and control of non-engineering measures early warning index system of research and application, in order to improve the technical level and effect of jiangxi mountain torrent disaster early warning and forecasting theory and technology support effect, is helpful to reduce to a great extent caused by mountain torrent disaster casualties and property losses.And according to the research situation at home and abroad, this paper introduces several kinds of method to determine the critical rainfall of the mountain flood disasters, analyzing various methods in the material, the applicability and limitations of typical geomorphic type and so on, combined with the actual situation of different regions in jiangxi province mountain flood disasters, through the typical basin analysis and calculation, the recommended several kinds of different areas suitable for our province mountain flood disasters early-warning index calculation method, the analysis of mountain torrent disaster prevention early warning index in jiangxi province research work to provide the corresponding reference.According to the Xiang Cun Ji and the conditions of mountain torrent disaster early warning monitoring facilities at the county level, recommendations based on Xiang Cun Ji and warning facilities at the county level of the calculation method of early warning indicators, and proposed the requirements of the early warning indicators.
