| Abstract: | GIS,SPSS17.0 and Excel were used to study the temporal and spatial distribution patterns of forest fires in Yichun forest region,Heilongjiang Province using the forest fire data for 1970-2010(except 1979,1997 and 2000).Results show that the 38 years of fire history can be divided into two stages: high fire occurrence stage from 1970 to 1978 and steady fire occurrence stage from 1980 to 2010,and the whole period shows a decreasing tendency.The main types of forest fires are general forest fire and bigger for... |
