Tree wave mi.rati.n across an elevati.n gradi.nt i. the Altai.Mountai.s,Si.eri.

引用

Journal of Mountai. Sci.nce 2017年第3期14卷 442-452页

作者： viacheslav i.kharuk Sergei.T.i. Mari. L.DVi.SKAYA Kenneth J.RANSON i.'ya A.PETROV Sukachev i.sti.ute of Forest SB RAS KrasnoyarskRussia Si.eri.n Federal Uni.ersi.y KrasnoyarskRussia M.F.Reshetnev Si.eri.n State Aerospace Uni.ersi.y KrasnoyarskRussia NASA's Goddard Space Fli.ht Center GreenbeltMarylandUSA

The phenomenon of tree waves （hedges and ri.bons） formati.n wi.hi. the alpi.e ecotone i. Altai.Mountai.s and i.s response to observed ai. temperature i.crease was consi.ered. At the upper li.i. of tree growth Si.eri.n pi.e （Pi.us si.i.i.a） forms hedges on wi.dward slopes and ri.bons on the leeward ones. Hedges were formed by prevai.i.g wi.ds and ori.nted along wi.ds di.ecti.n. Ri.bons were formed by snow blowi.g and accumulati.g on the leeward slope and perpendi.ular to the prevai.i.g wi.ds, as well as to the elevati.n gradi.nt. Hedges were always li.ked wi.h mi.rotopography features, whereas ri.bons were not. Trees are mi.rati.g upward by waves and new ri.bons and hedges are formi.g at or near tree li.e, whereas at lower elevati.ns ri.bons and hedges are bei.g transformed i.to dosed forests. Ti.e seri.s of hi.h-resoluti.n satelli.e scenes （from 1968 to 2OLO） i.di.ated an upslope shi.t i. the posi.i.n ri.bons averaged 155＋26 m （or 3-7 m yr^-1） and crown closure i.creased （about 35%-90%）. The hedges advance was li.i.ed by poor regenerati.n establi.hment and was negli.i.le. Regenerati.n wi.hi. the ri.bon zone was approxi.ately 2.5 ti.es （5060 vs 2120 ha^-1） hi.her then wi.hi. the hedges zone. Duri.g the last four decades, Si.eri.n pi.e i. both hedges and ri.bons strongly i.creased i.s growth i.crement, and recent tree growth rate for 50 year-old trees was about twi.e hi.her than those recorded for si.i.arly-aged trees at the begi.ni.g of the 20^th century. Hedges and ri.bons are phenomena that are wi.espread wi.hi. the southern and northern Si.eri.n Mountai.s.
