1)dendropyrochronology树木年轮火历史
1.As a significant cross-discipline of dendrochronology and forest fire ecology, dendropyrochronology is the science that uses tree rings to date and study past and present changes in wildfires, dating the fire scars left in tree rings to determine how often fires occurred in the past.该文对树木年轮火历史国内外研究现状进行了简要评述,国内树木年轮火历史研究尚处在起步阶段,国外树木年轮火历史研究主要集中在以下几个方面:1)火历史的时空格局特征,主要包括林火发生的时间间隔、空间范围、强度、林火发生的时空关联、林火发生与立地条件的关系、林火发生与物种演替以及树轮火疤与其他方法相结合的火灾判断等内容;2)火灾历史与全球气候变化的关系,主要包括火灾与温度和降水关系,如一般在当年干旱而前几年相对湿润时火灾发生;火灾发生与大尺度气候事件也有一定的关联,火灾一般发生在厄尔尼诺(ElNi?o)向拉尼娜(LaNi?a)转换的年代,而且相位组合比单个事件更容易引发火灾;3)火历史与人为活动及土地利用的关系,战争和人口增加容易引发火灾,而放牧活动却降低火灾发生频率,20世纪以来的森林火抑制降低了火灾发生频率却增加了大火发生的可能性。
