【文章內(nèi)容簡介】 ironmental 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, increased soil erosion and the environment continues to worsen, as torrential rains into a disaster has provided favorable conditions as the formation and the occurrence of flood disasters can not be ignored important factor Control measures for flood disasters Can be used for prevention of flood disasters engineering measures and nonengineering measures for prevention and treatment. Works include: flash ditch, debris flow, landslide。 Water reinforcement, flash floods and other disasters threaten Soil and Water Conservation District. Nonengineering measures include: meteorological, hydrological monitoring system, warning system and decision support system construction. The main research projects of nonengineering flood disasters prevention measures. 5 1, the establishment of meteorological and hydrological monitoring system According to sudden flash floods, regional characteristics, in a small basin, in the key areas of debris flow and landslides, increased rainfall and hydrological observation stations, automatic monitoring of key areas, rainfall warning station layout, realtime monitoring of rainfall, scattered residential areas can be Simple to install rain barrels manual observation, rainfall data collection, analysis of rainfall intensity on landslides, debris flow impact. 2, create a picture, video, multimedia monitoring system Because the visual image and video multimedia visibility, giving the effect of immersive, mudslides and landslides in key areas, add images, video multimedia monitoring project, usually transmitted by a certain time interval still pictures, start the camera when in the event of disaster function, realtime dynamic changes in transport during the scene of the disaster, flood control and disaster assessment to gather firsthand information. 3, the establishment of warning system Establish an accurate collection, transmission system and warning system, realtime collection of rainfall within the catchment, water level and flow of information, the establishment of multimodel hydrological, geological prediction system. Its main ponents include: data analysis, processing system。 water situation information, monitoring system。 torrential heavy rainfall disaster warning system。 flood forecasting and debris flow, landslide hazard warning systems. 4, the establishment of decision support system for flood disasters Create flash floods and geological disasters database, preparation of plans for the prevention of flood disasters, anized munication system of flood
