樹木年輪火歷史,dendropyrochronology
1)dendropyrochronology樹木年輪火歷史
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.該文對樹木年輪火歷史國內外研究現狀進行了簡要評述,國內樹木年輪火歷史研究尚處在起步階段,國外樹木年輪火歷史研究主要集中在以下幾個方面:1)火歷史的時空格局特征,主要包括林火發生的時間間隔、空間范圍、強度、林火發生的時空關聯、林火發生與立地條件的關系、林火發生與物種演替以及樹輪火疤與其他方法相結合的火災判斷等內容;2)火災歷史與全球氣候變化的關系,主要包括火災與溫度和降水關系,如一般在當年干旱而前幾年相對濕潤時火災發生;火災發生與大尺度氣候事件也有一定的關聯,火災一般發生在厄爾尼諾(ElNi?o)向拉尼娜(LaNi?a)轉換的年代,而且相位組合比單個事件更容易引發火災;3)火歷史與人為活動及土地利用的關系,戰爭和人口增加容易引發火災,而放牧活動卻降低火災發生頻率,20世紀以來的森林火抑制降低了火災發生頻率卻增加了大火發生的可能性。
2)tree ring樹木年輪
1.Correlation between chemical element contents in tree rings and those in soils near tree roots in the southern suburbs of Beijing,China.;樹木年輪與其根部土壤化學元素含量的相關性
2.In this paper, with an aim of better monitoring air pollution, we selected tree bark and tree ring core samples(willow, Salix matsudana)close to a smelting industry in northeast Beijing for magnetic studies.通過磁學手段以樹木年輪為研究對象,通過多參數磁學研究探討鋼鐵廠周圍環境污染的歷史。
3.The standardized(STD) chronology was established from tree ring data of \%Sabina przewalskii \%in east region of Qilian Mountains.祁連山東部地區樹木年輪年表具有明確的氣候學意義。
