Due to the variability and complexity of landscape design in space and time, it is difficult to accurately express landscape design only by relying on individual hand-drawn effects and text descriptions. Based on this, the application research of virtual reality technology in the integrated design of architectural landscape is carried out. First, through the analysis of virtual reality technology, the advantages of virtual reality technology are explored in depth, and then the advantages of virtual reality technology are applied to the 3D landscape modeling design. Finally, application examples are analyzed. The results show that the entire roaming scene more truly reflects The local topography and landforms realistically simulate the local architectural landscape and restore the damaged characteristic town. The average FPS of the user roaming scene on an ordinary computer is not less than 18 frames/s, and the browsing is basically smooth.

China is one of the countries with the most serious natural disasters in the world.In order to find out the historical disaster information in China,the attributes of disaster-bearing bodies,and the regional comprehensive disaster reduction and relief capabilities,the State Council requires each province to carry out the first national comprehensive risk census of natural disasters.Nine departments,including the emergency system,have the census tasks.Taking Fenghua district of Ningbo city as an example,its implementation of the census tasks by Fenghua district emergency system is illustrated in this paper.Through risk census,the distribution of major disaster-bearing bodies such as public service facilities,hazardous chemical enterprises and non-coal mining enterprises in Fenghua district is obtained,the information of disaster reduction capacity and historical disaster in key regions is figured out,and then the level of natural disaster prevention and reduction is objectively understood.It will provide natural disaster risk information and scientific decision-making basis for Fenghua District Emergency Management Bureau to effectively carry out natural disaster prevention and emergency management work,and to practically guarantee sustainable economic and social development.
