Study On Urban Disaster Prevention And Avoidance Green Space System

As a number of natural disasters,and sudden earthquakes,floods,typhoons and other disasters is very strong,is difficult to accurately estimate,and with the increase of concen-tration,the population of the city of the construction of the city,city residents face huge se-curity threats,city security has become one of the major tasks in twenty-first Century of a city the construction of the city and an important goal,the first is the safety of the city liva-ble city,and green city infrastructure is the most vitality of the city,has an irreplaceable position in the city of refuge for the function,so the construction of city disaster prevention green space system is very necessary,but at present our country on construction city disas-ter prevention hedge green space system has not been clear norms and standards,this paper on the basis of research and analysis,mainly including the construction of city disaster pre-vention The function of the green assessment,planning target,command system,index sy-stem,layout structure,evacuation channel system,facilities,management,placement,barr-acks and research for different types of green building disaster points of disaster prevention green space system.With a view to improving the existing urban disaster prevention and Disaster Prevention Green Space System in China,enhancing the ability of comprehensive urban disaster prevention and disaster reduction,and improving the safety factor of the city.Based on the current domestic suffered various disasters especially under the backgground of earthquake disaster prevention,put forward the necessity of perfecting the dan-ger avoidance system,through the analysis of learning Japanese disaster prevention park network system and the community disaster prevention system,and summarizes the defi-ciencies of China's disaster prevention hedge green construction system,combined with the actual situation of our current domestic disaster in China,and according to the specific dis-aster in different areas of the city,the reasonable construction in accordance with the featu-res of each city disaster prevention green space system,improve the comprehensive preve-ntion of all city disaster response and recovery ability.The main results are as follows:1)According to the city of our country,the disaster is different,according to different types of disasters,according to disaster prevention green space classification,increase the resear-ch points of the construction of flood control,fire,wind and green green green,green,gre-en sandstorm slide several types of green space.2)From the Japanese disaster prevention park network system,and the community disaster prevention system,learning foreign city green space comprehensive prevention network,and the public to participate in the practice of disaster prevention,combined with the real-lity of our country,the construction of new barracks resettlement system,in addition to the various types of equipment in the City Greenbelt Types,barracks resettlement system to avoid heavy casualties and losses occurred at the time of the disaster,effectively enhance the ability of city disaster prevention and mitigation.3)The construction of different city China's disaster prevention green space system has cer-tain reference significance,domestic city should be based on the city's main disaster and type two disaster planning,disaster fortification focus,to construct the corresponding system contain relevant content,and reasonable layout,comprehensive consideration,optimization,to maximize the protection of people's lives and the security of the property.
