| Our country is the most complicated hydrologic information in the world, most of the countries of the positive heavy task. Along with the growth of the population and economic and social development, the flood control situation of China took place the new change, faced with severe challenges. From our country in recent years, the characteristics of the flood disaster to see, mountain torrent disaster account for a considerable proportion of and the harm caused more and more serious, the casualty and property loss is more and more big.Yanping area within the boundaries the terrain complex geological conditions, with the river, the river is mountain river, the mountain of the typical flood jumped characteristics, fujian province is one of the mountain torrent disaster areas.This paper analyzed the reason yanping area nature geography and the social and economic situation of the basis, discusses the causes of the mountain torrent disaster science, research at present mountain torrent disaster prevention and control problems, and actively explore yanping area mountain torrent disaster prevention and control countermeasures and measures, and feasible measures.This paper is divided into six parts:The first part is a foreword. Mountain torrent disaster prevention and control of this research background, significance, express mountain torrent disaster prevention research situation at home and abroad, introduces the mountain torrent disaster prevention and control experience.The second part is the basic situation yanping area. Investigation and analysis of the geographical position, yanping area meteorological and hydrological, topography, geological structure, river system and other natural geographical conditions and social economic conditions.The third part is the mountain torrent disaster causes. The analysis yanping mountain torrent disaster area in regional and seasonal, sudden and sustainability, destructive five characteristics. Explore the mountain torrent disaster frequent four main causes:meteorological factors, geographical factors, hydrological features and human factors.The fourth part for the present yanping area mountain torrent disaster prevention and control the existing problems. There are mainly three problems:one is the construction of flood control works system lags behind, the flood control headquarters under decision system is weak, three is the flood control and disaster alleviation social consciousness.The fifth part yanping area for mountain torrent disaster prevention countermeasures and measures. In this part of the first four parts of the foundation, strengthening of the understanding of the mountain flood disasters, active exploration for the yanping mountain torrent disaster prevention and control measures, and puts forward to building with non-structural measures and engineering measures with the combination of system of disaster prevention and mitigation, and to enhance the ability of mountain torrent disaster prevention and control, ensure the safety of the people’s life and property. Engineering measures through the high standard, speed up the construction of medium and small rivers flood management, solid small watershed comprehensive management, in small reservoirs in real earnest problems such as strengthening the coverage to improve mountain torrent disaster prevention and control level. Non-structural measures to establish monitoring and warning system, the mountain flood disasters of prevention and control plan, a group of predicting the organization system, and mountain torrent disaster areas prone to publicity and training, and other means to improve "warning to the township, plan to the village, the responsibility to the people" the work mechanism, yanping area in China building monitoring and warning network and group of predicting the defense system, and realize effective defense mountain torrent disaster, minimize mountain torrent disaster bring losses of life and property.The first six divided into conclusion and prospect. The conclusion of this study, puts forward the direction of future research. |
