In the research process, I found Fuzhou urban green building disaster shelter stays in the initial stage, such as siting, erect signs, and in twenty-one disaster shelter, there is one that no longer exists but still identified as shelters; There are seven of the mountain parks, park slope in most places is too large, easy to trigger secondary disasters, disaster prevention is not suitable as a fixed shelter; There are four or located in Fujian Province, Fuzhou Inland River side, there were flooded security risks. These disaster shelter building from site selection to the theory of internal planning lack of professional guidance. In order to improve disaster shelter Fuzhou urban green space planning and construction theory, a clear urban green space in urban construction disaster shelters the important role and significance of a more systematic and scientific planning and design, the paper carried out as follows: Firstly, Through the urban disaster types, characteristics of the analyzed and classified, brief city's comprehensive disaster prevention system theory, summed up the city's five types of disasters, through the process of urban disasters the role of green space, disaster prevention and urban green space is proposed the city an important part of comprehensive disaster prevention, as well as through the prevention of urban green space on the domestic construction status of asylum summed construction of disaster prevention major problem. Secondly, through the access to large amounts of data, field surveys, literature searches summed urban green space disaster prevention function six kinds of forms, and practical experience in domestic and international disaster prevention were categorized and summarized for China's urban green space the construction of disaster shelters provide a theoretical reference. This article will urban green space disaster shelter divided into three categories, namely central shelter, fixed shelter and temporary shelter on the Japanese disaster prevention and disaster prevention construction, China has successfully concluded shelter, obtained disaster shelter planning principles, the basic requirements for siting, and through systematic analysis of the data and the associated mathematical theory of learning, disaster shelters proposed layout theory, the three types of disaster shelter service radius and scale, given Effective evacuation area, the capacity is calculated, and through a mathematical model to solve urban disaster shelter problem of the distribution. Finally, some examples of domestic fixed sum of urban green space ideal shelter layout, which mainly includes entrance humanized design, square rational distribution, improve the road system, the lifeline engineering construction, plant configuration and other aspects of the theory. The topics in Quanzhou and Fuzhou garden staff fieldwork in cooperation with the cities of refuge for all analyzes Fuzhou urban green construction status of disaster shelters, draw Fuzhou urban green space distribution of disaster shelters and service radius diagram, found in good condition in Fuzhou city green building, disaster shelter construction achieved initial results. However, in practice there are siting unscientific, unreasonable distribution, lack of green space per capita disaster prevention and infrastructure is still relatively weak, did not form a good disaster prevention system and other issues, and recommend areas for improvement for future construction, such as the overall planning to form a network; scientific siting, design development; rational distribution, highlighting function; propaganda exercise, and taking precautions. In theory suggests that at the same time, draw Fuzhou shelter ideal layout for discussion. Finally, the first one in Fuzhou disaster shelter - Hot Springs Park and Fujian disaster shelter is the first relatively complete construction of disaster shelters - Erythrina parks were compared on the proposed construction of the spa park some suggestions for the future construction of other disaster shelters for reference. Through the planning of urban green space disaster shelter theoretical research and case studies, hoping to improve the urban green space disaster shelter planning theory, able to shelter Fuzhou future planning and construction work and other related urban construction to provide some shelter thinking.
