Based On Natural Disaster Risk Prevention Of Urban Infrastructure Supply Countermeasures Study In China

Along with the development of society and economy, in the production and living of people is improved at the same time, also make the ecological environment has been severely disrupted. Especially in recent years, frequent natural disaster risk in our country, such as wenchuan earthquake, yaan earthquake, natural disaster risk is to China’s economic and social development and people’s production and living causing severe damage. Due to historical reasons, the role of disaster prevention and mitigation of urban infrastructure in China is not fully understanding, after the reform and opening up urban infrastructure construction scale expands unceasingly in our country, but its function has not been seriously of disaster prevention and mitigation, and buildings in the city, city roads, communication facilities and other infrastructure of seismic disaster prevention ability is insufficient. Whenever there is a natural disaster occurs, the urban infrastructure is often destroyed, even as the second killer of people’s life and property loss, not to mention its disaster prevention function, so the urban natural disaster risk problem of disaster prevention and mitigation, and establish and improve urban natural disaster risk prevention and control of infrastructure supply mechanism, reduce the risk of natural disasters happen the possibility of reducing the loss caused by disasters, make urban infrastructure in the prevention and control of natural disaster risk early warning, the function of relief, recovery and repeated construction has become a part of our is of vital importance to the disaster prevention and mitigation work.This article mainly USES the literature material method in the process of writing, system integrated analysis, the method of theory with practice, The article is important research content includes the following several aspects:First through the literature collection, sorting out and analyzing data, understand the countries such as Japan, Australia, UK research achievements of disaster prevention and reduction. Then analyzed the urban infrastructure supply and the relationship between natural disaster risk prevention and control, learning and using the theory of the integrated natural disaster risk management, analysis the characteristics and harm of the major natural disaster risk in China; In accordance with the standards of different categorizing natural disaster risk prevention infrastructure supply, such as divided into engineering measures and non-engineering measures, clear the infrastructure work in disaster prevention and mitigation of prevention, relief, recovery and reconstruction. Then analyzes the urban infrastructure supply and natural disaster risk prevention and control of the status quo, confirms our country has obtained certain achievements in the field of disaster prevention construction, proposed the supply of disaster prevention infrastructure humanist, scientific, pertinence, reusable, completeness, integration and so on six standards and principles, Found China’s disaster prevention infrastructure five main problems of the supply:Urban infrastructure hazard-affected ability is insufficient; Infrastructure, lack of regular maintenance and update; Relevant laws and regulations system is not sound; Underfunded lead to the shortage of infrastructure; Infrastructure construction technology lag behind. And analyzed the prevention and control of the United States, Japan and other foreign supply of urban infrastructure natural disaster risk experience and enlightenment:pay attention to the resources integration, construction of the whole society to participate in disaster relief mechanism; To establish and gradually improve covering the whole city, patency of refuge, escape system; Strengthening buildings, public buildings seismic disaster prevention function, fully prepared to daily disaster prevention work. Finally put forward the natural disaster risk prevention and control of infrastructure construction in China to supply four policy Suggestions are put forward:the first to establish a comprehensive, Chang Shexing natural disaster risk prevention and control of infrastructure supply departments and coordination; The second gradually establish and perfect the natural disaster risk prevention and control of infrastructure supply legal system; The third strengthen infrastructure supply natural disaster risk prevention supervision; Fourth, relying on science and technology, innovative technology for natural disaster risk prevention and control of the construction of infrastructure. In this paper, the main innovation of perspective is unique, ever though the study of natural disaster risk prevention is rich, but this article only choose the infrastructure supply this point of view, from the most basic is, provide the basis for the urban disaster prevention and mitigation. But this article have many shortage, such as data insufficiency.
