comparison of forest fire regimes between heilongjiang in china and ontario
abstract
this research summarizes and compares the differences in forest fire regimes
in the provinces of ontario, canada, and heilongjiang, china, as it relates to fire
suppression techniques, human activities, and climate change. before 2007, the total
burned area in heilongjiang was much larger compared than ontario. from 2000 to
2013, the total forest fire occurrences in ontario were greater than heilongjiang.
compared to ontario, heilongjiang experienced more forest fires >100 ha in size.
the main causes of forest fires in heilongjiang and ontario are human activities and
lightning, respectively. most tree species in heilongjiang and ontario are fire
resistant. but forest fires are major driver of forest ecology and forest stand dynamics
in both heilongjiang and ontario. the fire weather index system used in ontario
can also be applied in heilongjiang. historically, heilongjiang had relatively higher
fine fuel moisture code and temperature compared to ontario. further, the rolling
topography in heilongjiang causes the forest fire spread easier compared to ontario.
climate change projections for this century suggest that forest fire regimes will
become severe. we will experience more frequent fires, and more extreme weather
events. in addition to climate change, human activities and the development of fire
suppression technology can hold the key to the changes in fire regimes.
