【正文】 ters, causing huge losses, disaster prevention and disaster reduction has bee a 2 prominent issue. Must make the fight against flood disasters in an important position to conscientiously sum up experiences and lessons of flash floods characteristics and patterns of occurrence, adopt prehensive prevention and control measures to minimize losses caused by disasters. In 2021, led by the Ministry of Water Resources, in conjunction with Ministry of Land Resources, China Meteorological Administration and other relevant departments, has established a national leading group of mountain flood control planning to begin preparation of the national mountain flood prevention plan. October 2021, National Disaster Prevention Planning, flash report through the review to study and explore the characteristics of flood disasters occur and laws, scientific and reasonable planning countermeasures and prevention programs, and gradually establish and improve the disaster prevention and mitigation system for increasingly critical of the flood disasters in China to determine the control status of norms. According to the plan target by 2021, China will focus on prevention and control area in the flood disasters initially built for the surveillance, munications, forecasting, early warning and other nonengineering measures based, nonengineering measures and the bination of engineering measures, the mitigation system. Research Methods mountain flood warning system The main features of flood disasters 1, sudden strong Torrential rain caused by the disasters, the storm intensity, coupled with the specific geological, geomorphological and other surface conditions, leading to flash floods ferocious. Metamorphic massif in Henan Province, severely weathered limestone and granite mountains posed of mostly easy to erosion, is conducive to landslides, avalanches and debris flow formation。 flood disasters from 1999 to 2021 the number of deaths dropped to 1,100 ~ 1,400 people, but accounting for Flood death toll had risen to 65% to 75%。1 The early warning system of flood disasters significance As we all know, China is extremely frequent flood disasters hit countries, annual flood season flash floods triggered by rainfall, mudslides, landslides have caused heavy casualties and property losses, not only seriously threaten the lives of the masses, but the majority of seriously restricting the mountain hill areas of economic and social development and the people bee rich, of building a moderately prosperous society goals. According to statistics from 1950 to 1990, China39。s flood death toll from a total of million, of which the number of deaths hilly million, % of total deaths, average annual deaths 3707 people. Every year from 1992 to 1998 the number of deaths due to flash floods disaster is about 1900 ~ 3700 people, accounting for about flood deaths 62% ~ 69%。 2021,2021, respectively, of flood disasters caused by 767 and 815 deaths, accounting for the number of floods killed 49% and 76%. Thus, the number of deaths caused by flood disasters account for the proportion of the national flood death toll was increasing year by year trend, the harm caused by flood disasters increasing, more and more weight loss, flood control work has bee urgent to solve the outstanding problems in . Flood disasters over a broad area, with significant multiple, sudden and s
