摘　　要：为了科学地对发生森林火灾的森林进行灾后恢复,以湖南省为案例,选取影响森林火灾恢复力的年平均气温、年降水量、年日照时数、年发生火灾次数、单位面积活立木增长量等8项指标建立了恢复力指标体系,采用组合赋权法确定了指标权重,建立了森林火灾恢复力评价模型,对森林火灾恢复力进行了定量评价。结果表明:森林火灾恢复力主要受单位面积活立木增长量影响,湖南省森林火灾恢复力存在恢复力一般区和恢复力较弱区,没有恢复力较强区,说明湖南省森林生态系统受到森林火灾干扰后恢复潜力不高。In order to scientificallyrecover the burned forests, by taking Hunan Province as a case area, selecting eight indexes of influencing forestifre restoring force, such as the annual average temperature, the annual rainfall, the annual sunshine hours, the number of annualifre disasters, the growth in the stocking per unit area and so on, theevaluation index system of forest restoring force was established;by adopting the combination weighting approach, the eight indexes’weights were determined,thusthe evaluation model of forestifre restoring force was established and further, the resilience of forestifres was quantitatively evaluated. The results show that forestifre restoring force was mainly influenced by the stocking growth per unit area; Hunan forestifre restoring force can be divided into two kinds of regions, general restore ability region and weaker restore ability region, there was no stronger restore ability region. It is believed that theHunan Province forest ecological system’s recovery potential will not be strong if the system is disturbed by forestifre.
