The Impact of Precipitation Regimes on Forest Fires in Yunnan Province, Southwest China

Table 3

Spearman’s correlation coefficient between precipitation amounts, drought index values, and fire activity in fire season for five ecoregions in Yunnan province, during the period 1982–1988.

Ecoregion		Number of fires	Area burned
I	Drought	0.563	0.587
	Precipitation	−0.521	−0.534
II	Drought	0.687*	0.596
	Precipitation	−0.663*	−0.532
III	Drought	0.692*	0.677*
	Precipitation	−0.680*	−0.661*
IV	Drought	0.801*	0.785*
	Precipitation	−0.695*	−0.683*
V	Drought	0.792*	0.815*
	Precipitation	−0.689*	−0.662*

denotes the drought index values; denotes precipitation amounts in fire season; *denotes significance at the 0.0025 level; the significance levels were adjusted by Bonferroni test correction.
