Yano-Indigirka m'zigwa ndi mapangidwe ake

Otsika kumpoto kwa Yakutia, ndi malo a Madzi oundana ndi landforms lililonse cryogenic. Izi N. Thermokarst nyanja, m'madambo ndi zina zotero. Ambiri, malowa ndi Titafika pamalo.

Za malo a Yano-Indigirka lowland mtunda, za peculiarities wa nyama ndi zomera, za zaka ndi zina angapezeke m'nkhani ino.

A pang'ono za m'zidikha

Otsika - chigwa, amene kutalika si upambana mamita 200 pamwamba pa nyanja. Monga ulamuliro, otsika ndi lathyathyathya padziko lapansi, anamanga wamng'ono m'madzi, mtsinje komanso nyanja m'dambo. Iwo zili cavities akuluakulu ndi ang'onoang'ono, ndipo mukhoza kukhala pa nsanja ndi zigwa, ndi m'maenje a intermountain lapansi. Tikumbukenso kuti ndi lowland Caspian, yomwe ili m'dera la Russia, ili pansi pa nyanja.

Mbali ina ya m'zigwa, makamaka m'mphepete mwa nyanja, ndi iwo kawirikawiri kuli anthu. Ndipo zambiri zimachitika kuti anthu chongopeka kuwonjezera m'dera dziko la malo awa (mwachitsanzo, mu polders la Holland).

Location, mmene

Akuti lowland umachokera ku pakamwa Buor Hai kuchokera kumadzulo kwa mtsinje Indigirka kummawa, ndi madera ake aphimbidwa ndi ambiri Yakut m'dera Arctic.

Geographical amayang'anira Yano-Indigirka lowland - 46.602075; 39,230506.

lowland malo chimakwirira makilomita oposa 600 lalikulu la m'dera dziko, yomwe ili m'mphepete mwa chigwa kum'mwera kwa East Siberia Nyanja ndi Nyanja Laptev. Komanso, pali ankadziwana lalikulu la mtsinje Yana ndi m'kamwa mwa mitsinje ina wocheperako (Indigirka Omoloya), m'malo mwa awiriwo ndipo anatenga dzina m'chigwachi.

Fomu, mawonekedwe

Yano-Indigirka otsika ali kachigawo mawonekedwe. Mu gawo linafalitsidwa kwambiri a m'lifupi ndi makilomita 300 ndipo pafupifupi kutalika - mpaka mamita 30-80 pamwamba pa nyanja (ndi mamita mpaka 100).

M'zigwa lalikulu m'chigwa lowe ili mu gawo kumpoto kum'mawa kwa Siberia. Mogwirizana ndi a Kolyma m'zigwa, ankakhala mu gawo kumpoto kum'mawa kwa Yakutia, mu mtsinje beseni Chukochya Mtsinje, Alazeya ndi lamanzere gombe la malire m'munsi mwa Kolyma Mtsinje, ndipamene lowland lalikulu wotchedwa East-Siberia.

M'madera ena kuwuka yotsalira zitunda ndi lopangidwa ndi maziko olimba, mpaka mamita 558 (kutalika pazipita Yano-Indigirka lowland).

Age, kuphunzira

M'dera anafotokoza ikusonyezedwa ndi kukhalapo kwa angapo thandizo private zigawo Pleistocene zaka, amene ali mabwinja a mafupa yosowa ya zinyama ndi zomera. Ndime izi afufuza pa nthawi zosiyanasiyana zimene akatswiri monga A. A. Bunge (kapena Cherskii, mu 1891), V. F. Goncharovym, B. S. Rusanovym (1968) ndi N. K. Vereschaginym (1977 ) ..

Lazarev PA kufufuza zotsalira za yaikuluyi zinyama Plain kuyambira mu 1970 mpaka 2000. Mbali zina za malemu Cenozoic bwino anaphunzira ndipo anafotokoza mu mabuku ambiri a sayansi, koma pali magawo amene kuli adakali samadziwidwa mpaka kumapeto.

M'zaka zaposachedwapa, malo a m'zigwa za amapeza a mafupa wakale wa nyama ndi zomera akhala anapeza (Buluka Pleistocene).

Yano-Indigirka lowland: makhalidwe a m'derali, a dothi

Maganizo ichi pali nyanja wotchedwa Pavylon. Zopezeka mu izi kawirikawiri Siberia m'mbali zosiyanasiyana mapiri ndi kutalika kwa mamita 200 mpaka 300.

Apa chimakhala chogwidwa ndi morzlye thanthwe ndi Madzi oundana osatha landforms. Ambiri a m'zigwa za wapangidwa zosiyanasiyana nyanja, nyanja ndi mtsinje m'dambo wolemera mu ayezi malasha chifukwa predominance m'madera amenewa Madzi oundana a.

M'zigwa uli ndi khalidwe lake (ali ndithu kwambiri). Zikuphatikizapo matendawa, thermokarst (by ena. Alases) ndi zithaphwi, nyanja, imene kuuka ambiri Pingo. Komanso m'mphepete mwa nyanja, mitsinje ndi nyanja Tingaone mapiri ndi polygonal nthaka-baydzharahi. Yotsirizira ali mu mawonekedwe a micro- nthaka ndi meso (zamitundu kuyambira masentimita angapo mamita mazana ochepa). Ali ndi maphunziro a polygons, yamawangamawanga, mphete, mabwalo, ndi pa malo otsetsereka - magulu.

Yano-Indigirka lowland madera, nyama

udindo ankaimba apa zachilengedwe firiji Madzi oundana kuwuluridwa makumi zikwi zatsalira yaikuluyi matupi achisanu ndi ambiri nyama zina glacial nthawi. gawo ili la Siberia lalikulu - mmodzi wa zotsalira lotanganidwa ya zinyama yaikuluyi.

Chifukwa cha kukokoloka kwa madzi a nyanja ndi mitsinje, malo mwa nyanja ndi matenthedwe kumva kuwawa kugombe la nyanja zimachitika chaka imfa thawing ndi zotsalira za nyama wakale.

Flora: ubwenzi ndi zinyama za

Yano-Indigirka lowland ayezi zaka yaikulu Titafika pamalo-steppe danga ndi herbaceous zomera olemera. N'zodziwikiratu awa zikhalidwe ndi yabwino ndi chiwerengero cha nyama zinyama zafika kukula kwambiri. Izo zinali mu mochedwa Pleistocene.

Mu malo osiyanasiyana kumalo ozizira analenga kagawo kakang'ono, ndi msampha zachilengedwe, kumene umatanthauza "manda". Mu panali zambiri ziwonongeke nyama wakale.

Off gombe chimakhala chogwidwa ndi chitsamba chilichonse ndi Moss ndere Titafika pamalo ndi kum'mwera kwa zigwa mtsinje kukula nkhalango osowa deciduous.

Kum'mwera m'zigwa zigwa mtsinje ndi malo a m'nkhalango Titafika pamalo, zomwe zigwirizana wa larch ochepa.

Masiku ano, m'dera la Siberia mitundu wamba amene ali enieni kumadera amenewa, monga Titafika pamalo ndi Titafika pamalo nkhalango. Angapezeke kuno ndi ena zomera kutchulidwa Red Book of Yakutia. Kwenikweni kukula birch, msondodzi, kayandera, Aspen, stlanik, sedge, hawthorn ndi ena. Pakati nsomba zambiri zofala monga bream, Nsombazi, roach, Pike, mbewu Pike, grouper, ndi ena ambiri.

anthu

Yano-Indigirka otsika dera ndi aakulu mu Russian Arctic. Ozizira chilimwe amachokera ku nyanja ya East Siberia ndi m. Laptev. Koma mwezi wozizila kudela kubweretsa mphepo kum'mwera kuwomba kwa mapiri a Yakutia, kumene nthawi ino ya chaka olamulidwa ndi frosts kwambiri. Choncho, zomera ochepa kupulumuka ngati chilengedwe nkhanza.

Pamene mayiko amenewa ozizira anali Russian ofufuza m'zigwa sanali anathawira. Kumalo amenewa akumidzi chitukuko yaitali anakhala ndi moyo Evens ndi Yukagirs lero. Koma anthu wamba apa nthawizonse zakhala pang'ono kwambiri.

Timalankhula ndi anthu wamba kusaka, nsomba ndi mphalapala wawo amadalira kuweta.

Chovuta izi dera angaloŵe, koma yake wokongola komanso wovuta.
