Yano-Indigirka dooxada iyo kala soocista

Dhulka hoose ee waqooyiga Yakutia, waa meel ka mid ah jirkiisa la togaga caadiga cryogenic. Tani N. Guud Thermokarst harooyinka, biyagaleenka ahuba iyo wixii la mid ah., Arrintan waa Dhuldhoobo ah.

About meel ka mid ah Yano-Indigirka dooxada dhul, oo ku saabsan dhegyadii of the dhirta iyo ugaarta, oo ku saabsan da'da iyo macluumaad kale oo laga heli karaa this article.

A yar oo ku saabsan dhulka ee

Dhulka hoose - bannaan, oo sarajooggiisu kama badna 200 m kor ku heerka badda. Sida caadiga ah, dhulka waxaa ka dusha guri dhulka, dhisay dhalinyaro badda, Webi iyo baddii korsiiya. Waxay ku yaalaan godadka waawayn iyo kuwa yaryar, iyo waxay noqon kartaa mid ku saabsan madal iyo dhulka bannaanka ahba, iyo hogag of intermountain ah. Waa in la ogaadaa in dalkii dooxada ahaa Caspian, ee ku taalla soohdinta reer Russia, waxa uu ku yaalaa ka hooseysa heerka badda.

Muuqaal kale oo ka mid ah dhulka hoose, inta badan xeebaha, waa in ay inta badan dadku ku badan yihiin. Oo waxaa inta badan u dhacdaa in dadka kiimikaysan kordhin dhul ka mid ah goobaha ay (tusaale ahaan, in ka polders ee Holland).

Location, ilaa xad

dooxada loo tixgeliyaa kala afka Buor Hai ka xagga galbeed inay webiga Indigirka bari, iyo dhulkeeda daboolo inta badan Yakut of zone Arctic ah.

Dhuleed isuduwaha Yano-Indigirka dooxada - 46.602075; 39,230506.

deegaanka dooxada daboolayaa ka badan 600 oo kiiloomitir oo laba jibbaaran oo ah meesha dhulka, oo ku yaalla hareeraha soohdimaha koonfureed ee Badda Siberian Bariga iyo Badda Laptev ah. Sidoo kale, waxaa jira Delta weyn ee webiga Yana ah oo afka webiyada kale oo yar yar (Indigirka Omoloya), oo ka wakiil ah labada iyaga ka mid ah oo wuxuu kaxaystay magaca dooxada this.

Form, qaabka

dhulka Yano-Indigirka uu leeyahay qaab bilaha ah. In qaybta ubalaadhan oo ay width waa 300 km iyo celceliska height - ilaa 30-80 mitir heerka badda (oo ilaa 100 mitir).

Dooxada waa swampy ballaaran uu bannaanka ku yaalla qaybta waqooyi-bari ee Siberia ah. In lala Kolyma ee dooxada, oo ku yaalla qaybta waqooyi-bari ee Yakutia ah, ku jira xeedhada webiga Chukochya River, Alazeya iyo bangiga bidix oo ka mid ah qeybaha hoose ee River Kolyma ah, u yeela dooxada ballaaran loo yaqaan-East Siberian.

Meelaha qaarkood tiixtiix sara kaco haraaga ah ee ka kooban yihiin wadnaha daafaca, ilaa 558 mitir (height ugu badan ee dooxada Yano-Indigirka).

Age, waxbarasho

Meesha ku tilmaamay sida calaamad by joogitaanka tiro ka mid ah taageerada iyo kuwa gaarka ah qaybaha da'da Pleistocene, kuwaas oo ka kooban hadhaagii fossils dhif ah dubato iyo flora. qaybaha Kuwan waxaa laga soo bartay waqtiyo kala duwan by culimada sida A. A. Bunge (ama Cherskii, in 1891), V. F. Goncharovym, B. S. Rusanovym (1968) iyo N. K. Vereschaginym (1977 ) ..

Lazarev PA sahamiyey hadhaagii dubato bareejeeyo Plain ka 1970 si ay u 2000. Qaar ka mid ah qaybaha Cenozoic dambe si fiican u bartay oo ku tilmaamay in suugaanta ee sayniska, laakiin waxaa jira qaybaha kuwaas oo ku sugan ayaa weli ma ay aqoon ilaa dhamaadka.

Sanadihii la soo dhaafay, meelaha dalkii dooxada ahaa oo ka mid ah waa helaa of fossils qadiimiga ah ee xoolaha iyo dhirta ayaa laga helay (Marxuum Pleistocene).

dooxada Yano-Indigirka: dabeecadaha degaanka, carradu ah

In niyad-jabka waxaa jira baddii la yiraahdo Pavylon. Helay kuwaas oo Siberian geesaha dhif ah isugu soo buuraha leh height ka 200 ilaa 300 mitir.

Halkan waxaa ku badan dhagaxa weyn morzlye iyo jirkiisa dilka ah , togaga. Inta badan dhulka dooxada ah ka kooban yahay noocyo kala duwan oo badda, baddii iyo webiga korsiiya hodan ku ah barafka lafo sabab u badan yihiin ee, kuwaas oo qaybo ka mid ah jirkiisa ah.

Dooxada waxay leedahay astaamo u gaar ah oo ay (ay ku jiraan waxyaabo badan oo ilaa xad ah). Kuwaas waxaa ka mid Niyadjabka thermokarst (by dadka kale Alases.) La meelaheeda dhoobada, harooyinka, in ka badan taas oo ku kici badan Pingo. Sidoo kale xeebaha iyo badaha, webiyada iyo harooyinka loo arki karaa buuro iyo polygonal ciid-baydzharahi. Arintaan waa qaab la siinayo ciidda iyo Meso (tirada laga bilaabo dhowr sentimitir in dhowr boqol oo mitir). Waxay leeyihiin dulmari of geesoolayaashu, sharooto, siddo, wareegyada, iyo dhaadhacyadii - guutooyin.

Yano-Indigirka dooxada juqraafiga, xoolaha

Doorka halkan ciyaaray jirkiisa qaboojiyaha dabiiciga ah la ilaashaa, tobanaan kun harta bareejeeyo meydadka la qaboojiyey iyo nuujiya kale oo badan muddo glacial. Tani waxay qayb ka mid ah Siberia ugu badan - mid ka mid ah hadhaagii ugu mashquulsan ee dubato bareejeeyo.

Sababo la nabaad guurka biyaha ee haraha iyo webiyaasha, xeebaha iyo xeebaha abrasion kaamerada badaha sanad walba khasaare diirran iyo haraaga xoolaha qadiimiga ah.

Flora: xiriirka la dubato ah

Yano-Indigirka dooxada da'da barafka waa meel Dhuldhoobo-steppe weyn leh Dhirta hodan herbaceous. In suurtagalnimada oo dhan, kuwaas oo xaaladaha xad wanaagsan iyo tirada dubato naasleey ayaa size muhiim ah gaaray. Waxay ahayd dabayaaqadii Pleistocene ah.

In meelo kala duwan Polar abuuray Misbaax, waa dabin dabiiciga ah, halkaas oo ay ka dhigan tahay "xabaalo". In iyaga waxaa jiray baabba 'aad u weyn ee xoolaha qadiimiga ah.

Xeebaha Dadwaynaha geed iyo Dhuldhoobo planus ajada iyo qaybta koonfureed ee webiga dooxooyinka koraan kaymaha kaymo dhif.

Koonfurta, dooxooyinka webiga dooxada yihiin meelaha kaynta-Dhuldhoobo, taas oo ka kooban larch ah Finensej.

Maanta, ee gobolka this ee noocyada caadi Siberia u gaarka ah kuwa gobolada, sida Dhuldhoobo iyo Dhuldhoobo kaynta. Waxaa halkan ayaa laga helayaa iyo qaar ka mid ah dhirta ku qoran Kitaabka Cas ee Yakutia. Asal ahaan koraan bjørk, safsaf, kayandera, Aspen, stlanik, sedge, Hawthorn iyo kuwo kale. Waxaa ka mid ah kalluunka waa badan yihiin sida bream, sturgeon, baran-, Pike, abuur, Pike, grouper, iyo kuwo kale oo badan.

dadka

Yano-Indigirka gobolka dhulka waa ugu daran ee Arctic Ruush ah. xagaaga Cold badda ee Siberian Bariga iyo Laptev m. ka yimaadaa. Laakiin qabow ee xilliga qaboobaha keeni dabaylo koofureed buunankay ka buuraleyda ah Yakutia, halkaas oo inta lagu jiro xilliga this ee sannadka garoomada by dhaxan daran. Sidaa darteed, dhirta yar ku noolaan karaa in sida jawi adag.

Oo kuwaasu markay dalalkan oo qabow ahaayeen sahamiyayaal Ruush, dooxada ma waxaa la goostay. Meelahaas waxaa meelaha durugsan ilbaxnimo ayaa muddo dheer ku noolaa oo ku nool Evens iyo Yukagirs maanta. Laakiin dadka deegaanka ah halkan ayaa had iyo jeer ahaa mid aad u yar.

Wadahadal dadka deegaanka ugaarsadaan, kalluumeysiga iyo dhaqashada.

Adag ee gobolka this dhex milmin, laakiin gaar ah u qurux badan oo dahsoon.
