【正文】 rs database, preparation of plans for the prevention of flood disasters, anized munication system of flood disasters, prevention of flood disasters, and disaster assessment system, mand system and so on. 5, the establishment of regulations and policies mountain flood prevention system By means of laws and policies for disaster risk areas mandatory for torrent control and management, norms, constraints caused by various human 6 activities, disaster aggravated disorderly conduct, has been damaged from the root to prevent the continued deterioration of the ecological environment. Improve and perfect the relevant laws and regulations, in particular, focus on prevention and control to make the area flood disasters Forest and relocation, environment protection and other policies, laws and regulations are strictly enforced. 6, to raise public awareness of flood disasters defense Activities in areas prone to flash floods, people always thought the string taut defense flash. Awareness training should be prepared in peacetime to enable the masses to understand familiar with the alarm signal and the transfer line。s annual flood disasters account for about 80% of flood disasters. 4, regional apparent strongprone Flash floods occurred mainly in the mountainous, hilly and mound, especially in the center of the storm area, storm impact when the easy formation of surface runoff, leading to flash floods, scour disaster. The causes of flood disasters The flood disaster in the main stream and weather, topography and human factors and so on. Sudden flooding rain is the main factor of flood disasters caused by heavy rain causes of the formation is the main reason for the flood disaster, coupled with human factors, the impact of topography, but also contributed to the formation of flood disasters. 1, the precipitation is caused by the most direct cause of flood disasters Uneven distribution of rainfall during the year, the annual variation and other characteristics, due to different conditions produce rain, flood with 4 strength, very vulnerable to flood disasters. From the statistics of view of flood disasters, longduration highintensity rainfall and storm surge cause flash floods, slope saturated soil moisture, soil softening, strength weakening, bined with rain or rock fractures along faults into the ground, leading to the collapse slip, creep, shallow landslides and debris flows occurring on a large, strong hydrodynamic conditions and poor geological development of the valley, as the environmental conditions of flood disasters. 2, the terrain is the basis of factors that lead to flood disasters Steep topography as floods, mudslides, landslides provides a powerful potential, so that rainfall generated runoff down slope down to the valley together, quickly forming a strong peak flow, and thus trigger the occurrence of debris flow and landslides. 3, human activities are intensifying an important factor in flood disasters occurred Good ground cover can play a solid role in soil water conservation, prevention of flood disasters for the important significance. Vegetation on the ground to prevent water erosion, surface runoff can reduce the convergence speed and reduce the occurrence of flash floods and damage. Human production, living, construction and other activities on the environment damage and the damage to natural vegetation, inc
