Kodi akuuza odulidwa mtengo

Kudutsa nkhalango ndi ndinazindikira chitsa akale, chidwi munthu ndithu kuima ndi kulabadira gawo m'mbuyo kwa mtengo. Kodi amakumbukira? Kuti ine ndikhoza kukuuzani, kupeza mawu ake? Erasing ku cutoff pachikuto cha Moss, n'zosavuta zindikirani mabwalo anawoloka ndi ming'alu. mtengo mphete akhoza kundiuza kwambiri. Zomera achinyamata chake mayendedwe amoyo, mwaoneka ozizira ndi otentha, masiku youma. Pamaso pa anthu wodziwa anaulula chaka ndi chaka, khumi pambuyo khumi. sayansi kunayambika posachedwapa, umatchedwa dendrochronology.

Lingaliro la dendrochronology

Phunziro zigawo mtanda sikovuta. Mtengo odulidwa ndi kufufuza maso, aliyense wosanjikiza pachaka amayezedwa millimeters. Malinga ndi miyezo anapanga ndandanda wapadera, izo zikusonyeza kusintha mphete makulidwe. Ndandanda kukwawa ngati kakakulu mphete onse (yabwino kwa zaka nkhuni), Zithunzi za yafupika pamene zaka anali wouma, katundu. Atalipenda atsopano odulidwa pansi pa mtengo, ndipo chiwembu, n'zotheka kupeza amafotokoza za moyo wake, kuonetsera nyengo pa moyo wa zomera, izo ndi, zaka zomalizira za nthawi yathu. Kupeza mu nkhalango kudula mtengo wakale, muyenera kuchita ntchito zomwezo ndi kutenga ndandanda. Pa kudzakhala kotheka kuweruza nyengo mu nthawi imene unakulira. Kuyambira m'chaka cha inu mukhoza kupita mwakuya mu mbiri ya chaka.

Koma si onse mophweka. Mu nkhalango European mitengo wakale chiyani sapulumuka zaka oposa mazana atatu, mazana anai, koma kuti thundu nthawi zina kuti theka Zakachikwi. Koma apa ndi kuphunzira yolimba odulidwa m'malo ovuta. Yosokoneza mphete zinsinsi m'malo monyinyirika. Mu malo zambiri zaphindu anasonyeza kuti asayansi la America. Pali ena mitengo moyo zaka chikwi. Izi ndi zina gymnosperms, chikasu paini, Douglas Oil. Panali ngakhale ya m'mapiri paini, amene anakhala anayi ndi theka zaka chikwi. Pa zofukulidwa pa malo a amwenye okhala anaona kudula anapezeka, amene akanakhoza kupanga dendrochronological zithunzi pa Zakachikwi wonse.

The mphete pachaka. Research ku Russia

Kwa zaka zambiri asayansi afufuza yekha nkhuni America. Europe anali malo woyera m'munda. Only pambuyo pa nkhondo mu Russia, asayansi akhala akuyembekezera Spila wakale. Zinali zabwino phunziro la kumpoto. The dothi bwino wothira nthaka mazira wateteza makungwa ambiri mtengo waukulu. Chachikulu "Pokolola" asayansi nkhuni anasonkhana pa zofukulidwa mu Novgorod wakale. Kumeneko anapeza zikwi zingapo Mitundu yosiyanasiyana, stratified pa mzake pa kuya osiyana. Wosanjikiza ndi wosanjikiza necropsied asayansi zinthu pofukula: risers mipingo, fufuzani yazokonza pansi, fufuzani m'zitsime. Akupeza anapezeka pa akuya eyiti mita. Koma kodi muvale apeza zaka anthuwo? Magawo a mtengo anali okonzeka ndi makope oposa zikwi zitatu. Aliyense mtundu anayenera kumanga sikelo yawo dendrochronological.

Dendrochronologists anachita ntchito yopambana. Iwo chabe alimbane zithunzi. Kukhazikitsa Buku ndandanda anali kuphunzira nkhani yonse ya wakale mzinda, amafotokoza, kudziwiratu zimene chaka linamangidwa kapena kuti dongosolo matabwa.

Aegean dendrochronological ntchito

Ntchito mokweza Aegean Dendrochronological ntchito wakhalako zaka 35. cholinga chake - kulenga dendroshkalu mtheradi kwa Middle East ndi zigawo Aegean ndipo kuphatikizapo mitengo woyamba Zakachikwi BC ku zinaonetsedwa pa chionetserocho ano. Ntchito wochitidwa ndi asayansi pa University Cornell, USA. Main zotsatira:

• Anagonjera mtheradi mitundu dendroshkaly monga thundu, mkungudza, mlombwa, paini. nthawi yawo akuti 750 ga BC.
• Anamaliza ntchito yomanga Aegean akuyandama dendroshkaly mwandondomeko zaka 2657-649 BC (kwa mlombwa).
• Komanso pa odulidwa mlombwa mtengo athandiza kumanga dendroshkalu akuyandama pa nthawi 2030-980 BCE. Zotsatira zinasindikizidwa mu 2005.
• nkhani kudziwika anali kudziŵika kuti "Rome mipata" ndi Eva-nkhani.

Zipambano za Asayansi American amaona maganizo, kuyambira Mwina zolakwa zina, kwa zaka 100 200.

Research ku Finland

Limodzi mwa madera ngoyenera pa phunziroli inali kumpoto Finland. Mu malo awa, mzere akudutsa malire nyengo. Professor Jan Esper amanena kuti makungwa olowa kusunga nkhani zonse kwa mazana a zaka. Choncho, kagawo ka mtengo, agona mu nyanja ozizira, limatiuza zambiri. Kumpoto kwa Finland pali zambiri nyanja, zimene zimasunga mfundo wapatali. Dendrochronologists amadzinenera kuti iwo angakhoze kuwulula zinsinsi nyengo ya zaka zikwi ziwiri. ntchito Laboratory ntchito zitsanzo wapadera kubowola pamanja mtengo mphete zinachotsedwa. Kenako kufufuza maso ndi ntchito makompyuta. Dendrochronological kukopedwa zithunzi athandiza kutulukira mmene nyengo zasintha ndipo ngakhale pamene pa dera la kuphulitsa mapiri zinachitika.

kusintha kwa nyengo

Malinga ndi zimene analandira, asayansi anali kupeza kuti dziko lililonse Zakachikwi kutentha pafupifupi kubwera madigiri 0,3. Uwu unakhalapo mpaka pachiyambi cha zaka mazana makumi awiri - ndi Industrial utasintha a dziko. Development patsogolo sayansi ndi luso kwachititsa chakuti m'dzikoli kwambiri kuchuluka kuchuluka kwa mpweya woipa. Nthawiyi Dendrochronologists sanapite mwatsatanetsatane.

Mu masiku a omenyana achiroma nyengo anali wotentha kwambiri. "Gawo ofunda" angatchedwe ndi Zapakati. Ndiye anadza chithunzithunzi ozizira, amene anapitilira chaka chilichonse mpaka 1900. munthu masiku ano, m'malo mwake, tsopano nkhawa likutentha. Monga mukuonera, ngakhale kagawo ka nthambi ya mtengo akhoza kundiuza kwambiri. Mwatsoka, mkubwela mmene kutentha, ndi mikhalidwe imene zodetsa mlengalenga ndi nyengo zimatengera, kumlingo, ndi zochita za anthu, deta ya dendrochronology angavomereze yekha kusinthasintha kutentha.
