Yintoni na ring yonyaka? Uhlalutyo olunzulu

Eli nqaku lichaza ukuba umsesane ukukhula, kuba indlela ekwenzeka ngayo, apho zifumaneka khona, sele bafunda ntoni inzululwazi amakhonkco.

Imithi and Life

Ubomi emhlabeni yethu kwasekwa kwaye ikhona ngenxa izinto ezininzi, yaye omnye wabo - na sisincoko efanelekileyo zerhasi emoyeni. Ngokucace kakhulu, kukho ioksijini eyaneleyo. Zisixelela izityalo, ezitshintsha icarbon dioxide okhutshwa ngumntu ezininzi izidalwa eziphilayo. Okwangoku, kuphuhliswa kakhulu kunye namazwe oluphucukileyo esweni ngokungqongqo urhulumente kwamahlathi zabo, kuquka ukudala iipaki zesizwe, apho kudibana khona imithi ezindala kakhulu. They are umdla kuphela ukusuka kwindawo yobuhle lwembono, kodwa ngenxa yokuba izazinzulu sisajongisisa ngolwazi kwamaxesha elidlulileyo, kwaye ubudala imithi bubonwa ngokusebenzisa amakhonkco umthi. Kodwa yintoni na lo msesane lonyaka, kutheni usenziwa naxa ukongeza kukho imithi? Ngokwenza njalo, siya kuqonda, kwaye kweli nqaku.

definition

amakhonkco ukukhula ngonyaka, okanye umaleko yonyaka, ebizwa intsimi ukukhula wovandlakanyo izicwili izityalo kunye nezinye iintlobo izidalwa eziphilayo, umzekelo, umngundo kunye mbambela. imbonakalo yabo ngenxa utshintsho zemozulu kwamaqondo obushushu okanye ezinye izinto. Ngoku siyazi ukuba yintoni ngekhonkco yonyaka.

Kodwa amakhonkco kakhulu uphawu libizwe nokukhula kuvandlakanywa uhlobo enemithi zezityalo ongatshiyo. Ngakumbi abo ezikhula kwisibanzi ziingcathu, xa ixesha ehlotyeni ithende nokukhula cambium mzuzu kunye nexesha lokuphumla ekwindla nasebusika zonyaka. Ukuba sithethe malunga imbonakalo emakhonkcweni, nganye yahlulwe kabini: emnyama kunye nokukhanya. Conifers umdla ngenxa amakhonkco zabo zonyaka zibonwa ngokucacileyo, ekubeni kweenkuni, uMyili kamva abe umthunzi emnyama abahlukene. Ngoku siyazi ukuba yintoni ngekhonkco yonyaka. ukufunda yabo kwakubandakanya isayensi dendrochronology.

dendrochronology

Dendrochronology - yinto uqeqesho yenzululwazi isebenza iziganeko rhandzana, ngezimanga zendalo kunye iziphumo zakudala evela izifundo amakhonkco umthi ngomthi okanye nezinye zebhayoloji ukuba labo.

Umzekelo, indlela ezininzi eziqhele ukusetyenziswa ukuba ukugqiba kwiminyaka ezinye izinto okanye izakhiwo somthi emakhonkcweni ngonyaka.

Luhlobo luni na inzululwazi sisenza oko siye saqonda. Ngoku makhe sikhangele ukuba ukwenza njani namakhonkco zonyaka.

inkqubo ukwakheka

Njengoko sele sibonile, zibekiwe imithi ezikhula kwiindawo kunye amaxesha onyaka ngokukhawuleza. Ngamafutshane, ehlotyeni kwaye ebusika ukuba akukho kukhula ngenxa ngokulinganayo utshintsho kwamaqondo obushushu kunye nezinye iimeko. Oku kukhokelela kwinto yokuba kukho umaleko iinkuni, bekhula ebusika, ehlotyeni yahlukile iimpawu ubunzima: umbala, ukuxinana, ukuthamba, njl Ukuba sithethe ebonisa ezibonwayo, ngoko umnqamlezo yabona kunqunyulwa buti umthi kunokubonwa isakhiwo ecacileyo, ukuba imilo umsebenzi osontiweyo concentric.

Yiyiphi na kumiselwa ngamakhonkco ukukhula?

Ngokusisiseko - yinto ubudala. umsesane ingqamana nonyaka omnye, ngokutsho balo babulingana nesandla kwaye kwinkangeleko kugwetywa kwi oko ke ngonyaka ukusuka kwindawo zemozulu lwembono: iqondo lobushushu uqikelelo, imvula, rhoqo yawo, njalo-njalo. Sebenzisa le ndlela yokuqingqa ubudala ezinye iimveliso bamandulo yeplanga: bona aqingqwe, khangela inani nemisesane, yaye emva koko xa kuthelekiswa nesampula, ogama yobudala uyaziwa. Ngoko ke, uyakwazi ukubona xa wagawulwa phantsi umthi, owaba izinto zesifundo.

jikelele silwane

Njengoko sele kukhankanyiwe, amakhonkco yonyaka zifumaneka kuphela imithi kodwa kwihlabathi isilwanyana. Liyafumaneka kuloo iithishu okanye ukwakheka amathambo, leyo ekhula, kodwa ke basengozini iimpembelelo kwemozulu, utshintsho ngamaxesha athile xa amaqondo obushushu. It scales, amathambo kunye amaphiko ezinye iintlobo zentlanzi, amaqokobhe silwanyana yolwazi eziindidi ngeendidi, nemilomo kunye namathambo iintaka, izilwanyana, iimpondo, amathambo, ezinye izilwanyana. Ngoku siyazi oko amakhonkco yemithi eziphilayo. Ngokutsho kwakhe, izazinzulu wagqiba ziyafana zonke, njengoko kunjalo wemithi ubudala, ingakumbi imozulu kwexesha, njalo njalo.
