Lightning fire has its own unique time and space law. In this paper, to collate data on the Daxinganling nearly 40 years of lightning fire lightning fires in the region underlying data and meteorological data analysis using Excel, SPSS and ArcGIS software. The existing lightning fire at home and abroad research and data Daxinganling comprehensive demonstration lightning fires difficult to control this natural phenomenon, the formation mechanism of the complexity of the Occurrence of the unique, the difficulty of the forecast monitoring and early warning systems Necessity Daxinganling forest fire fire and frequency research showed that: Daxinganling cause of the fire, a fire due to the recording of the 1494 forest fires, lightning fires 545 times, accounting for 37%, is an important part of the Daxinganling forest fires; region occurred in the fire about 37 lightning fires occurred in 13.6, 87 years ago, lightning fire occurrence frequency of the total 33%, and 87 years accounted for 59%, an increase of 26 percentage points, lightning fires destroy the proportion of have increased significantly, the area of ??deforestation from 1% to 3.4%. The Daxinganling lightning fire in time and space studies have shown that: Daxinganling region, Heilongjiang Province, almost every year occur with a certain periodicity, often after several years of low, causing the frequency of lightning fires, 87 years ago, the frequency of occurrence of lightning fire cycle is 4 years, 87 years after the lightning fire frequency increased to 2-year cycle; lightning fires occurred mainly in the summer and autumn of each year, and are concentrated in May and June, the two seasons lightning fires occurred 403 times, total lightning about 72.5% of the fire; lightning fires occurred hours during the day, and concentrated in the morning from 10:00 to 17:00. Lightning fires occur more scattered throughout the region have a lightning fire. Five amur, call Plata, Songling, the new forest lightning fire high incidence, accounting for 58.9% of the lightning fires occurred. The Daxinganling weather conditions analysis shows that the impact of lightning fires: lightning fires and meteorological factors, average precipitation, relative humidity, average wind speed negatively correlated with average summer temperature is positively correlated. Precipitation occurrence of lightning fires is a control factor, lightning fires occur frequently when the precipitation of 400mm when precipitation over 500mm, lightning fires occur rarely; temperature is a key factor affecting the occurrence of lightning fires, when summer temperatures in the 14 ℃ probability of lightning fires is very small, accounting for only 8%. Temperatures between 14-20 ° C the lightning fire high-fat segment, accounting for 68%, most of the lightning fires occur at this temperature. When the temperature is higher than 20 ° C when the lightning fire reduced. The history of the development and monitoring and forecasting Overview of lightning fire early warning system and its main function by comparing the lightning fire at home and abroad. Domestic lightning fire monitoring and forecasting a late start compared with developed countries, to be quickly improved. Lightning fire early warning system combines satellite monitoring, monitoring observatory, ground patrol three ways to form a three-dimensional safety net, to provide forecasts for forest fire prevention, monitoring and loss of large amounts of data, will help to avoid fires and catastrophic fire occurs, reduce fire losses.
