Study On Forest Fire Spatial Temporal Pattern And Influencing Factors In Fujian Of Sanming City From 2000 To 2014

As a high incidence of forest fire zone,Sanming City studying the spatial pattern of its forest fire and impact factors,is not only for the Sanming City forest fire management and forest fire prevention project to provide a scientific basis for the same time to improve the Sanming precautionary measures against forest fires,Therefore,based on the forest fire data from 2000 to 2014 in Sanming City of Fujian Province,which analyzed the safety of forest resources.The author analyzed the spatial and temporal changes of forest fires,and combined the monthly forest fire changes,the forest fire changes and the forest fire danger area which combined with the location factors,the meteorological factors,the meteorological factors,the infrastructure factors and the terrain factors that affect the forest fire changes in Sanming city Over-fire time and influencing factors of multiple linear regression model,and then analyze the main influencing factors of forest fire in Sanming City,Fujian Province,the conclusions are as follows:(1)Forest fires in Sanming City,Fujian Province During 2000-2014,the overall forest fires in Sanming City of Fujian Province showed an upward trend and then a downward trend.The winter was the high season for forest fires in Sanming City,Fujian Province.The forest fires took up the entire territory of Sanming City The occurrence of forest fire was 47%.The change of forest fire month showed the change of double valley.Among them,the forest fire had the highest frequency in June and the forest fire was most likely on the 11th to 15th day of each month.(2)The spatial distribution of forest fire in Sanming City,Fujian Province shows that the distribution of forest fire in 2008 shows obvious agglomeration characteristics.The northeast and northwest of Sanming City are the main forest fire gathering area.In January and December,Fire distribution throughout the month basically the same,there are two forest fire gathering area in the northwest and northeast.Annual center of mass transfer:2000 Meilie zone->Sanyuan zone in 2006->2008 Jiangle County->2014 Meilie zone;monthly heart mass transfer line:January Mingxi County->June Sanyuan zone->December in Jiangle County.The distribution of low,medium and high-level fire hazards in Sanming City is staggered.The low-fire danger zones are mainly distributed in the central area of Sanming City.The high-fire danger zones are located in three counties of Jianning County,Yong'an City and Youxi County in the north,southwest and southeast regions.(3)For the main factors affecting the forest fire changes in Sanming,Fujian,the main influencing factors of forest fire in different months are different.In January and December,the distance to the railway" in the forest fire model is the most important factor in the forest fire changes,Latitude and longitude factors,compared with the latitude and longitude on the forest fire month strong changes,and latitude and longitude factors are the second impact of forest fire on the second factor.In terms of meteorological factors,monthly average precipitation has a significant impact on the forest fires in January and December.The monthly average temperature in June is a major factor affecting the month.The main influencing factors of different years are different.In 2008,distance to railway,average longitude,average monthly precipitation and average elevation are the main influencing factors.The relative important factor of 2014 forest fire factor is month Precipitation,Provincial Highway Distance,and Average Grade.The influence factors of forest fire changes affected by different forest fire districts are different,and the main factors influencing forest fire changes are average latitude,average longitude,average monthly precipitation and average elevation.The main factors of forest fire change are:average longitude,distance to railways,distance to residential areas,average monthly precipitation,average monthly temperature,and average gradient;impact forests in high fire risk area model.The main factors of fire changes are average latitude,average longitude,distance to the railway and average monthly precipitation.
