摘要
以影响河南省森林火灾发生、蔓延的７个主要且稳定的火险因子作为区划指标，应用灰色聚类方法，对河南省６０个县（市、林场）的在林火灾危险程度进行了区划，结果基本符合实际情况，从而为河南省森林防火规划的制定，设施建设资金的投放等提供了科学依据。
According to the seven principal and steady factors affecting forest fire occurrence anddevelopment,the forest fire risk degrees of sixty units(counties,cities’forestry farms)inHenan Province are classified by using the gray cluster methed.The results are consistent withrealities and thus supply a scientific basis for the drafting of forest fire prevention programmesand the arrangement of facility-building fund.
