Stanovoe Upland - roob kab ke ntawm sab hnub tuaj Siberia. Nws stretched nyob rau hauv cov kev taw qhia ntawm sab qab teb hnub poob mus rau sab qaum teb sab hnub tuaj rau 700 km. Qhov dav ntawm lub roob system yog ntau tshaj 200 km. Sab hnub poob mus txog ntawm ntug dej hiav txwv ntawm Lake Baikal, thiab sab hnub tuaj ntawm cov peaks mus txog qhov siab ntawm tus dej. Olekma. Lub roob siab siab (3,000 m), uas hloov pauv nrog cov pob zeb sib tshuam (hauv qhov siab ntawm 800-1,000 m saum toj no hiav txwv), qhov no yog qhov koj tuaj yeem pom Stanovoye Upland. Kev tswj hwm ntawm lub roob no yog: 56 ° 05'00 "sab qaum teb latitude, 114 ° 30'00 " sab hnub tuaj longitude. Ntawm daim duab qhia chaw ntawm Russia, nws nyob rau thaj tsam ntawm Buryatia (qhov nruab nrab ntawm Asia).

Rib

Lub roob no tau muab faib ua 7 thaj, nyob ntawm sab hnub poob mus rau sab hnub tuaj raws li hauv qab no:

South Muisky ridge nrog qhov siab tshaj plaws Muisky Giant (3 067 m).
North-Muisky Range - qhov siab tshaj plaws - 2,537 m.
Verkhneangarsky ridge. Qhov siab tshaj plaws yog 2,641 m.
Kodar Ridge yog txuas ntxiv ntawm North Muya. Qhov siab siab tshaj plaws - BAM ncov (3,072 m).
Udokan Ridge nrog qhov siab tshaj plaws ntawm 2,561 m.
Kalari Ridge yog qhov txuas ntxiv ntawm Udokan. Qhov siab tshaj plaws yog tsawg dua li ntawm lwm qhov chaw siab. Qhov siab tshaj plaws yog Mount Skalisty Golets, 2,519 m siab.
Nizhnekalarsky ridge yog ib ceg ntawm Kalarsky ridge. South.

Txhua 7 qhov chaw ntawm Stanovoy Upland yog sawv cev los ntawm taw tes peaks, pob zeb ridges nrog bald terraces. Cov no yog cov alpine landforms.

roob bass

Nruab nrab ntawm cov ridges piav saum toj no muaj cov roob loj:

Lub Muisko-Kuandinskaya phiab nyob nruab nrab ntawm South Muisky thiab North Muisky ridges.
Verkhneangarskaya hollow. Nws nyob nruab nrab ntawm North Muya thiab Upper Angara ranges.
Chara Kev nyuaj siab. Nws nyob nruab nrab ntawm Kalarsky, Kodar thiab Udokan ridges.

Tag nrho cov phiab no yog hom Baikal, nyob ntawm qhov siab tsis tshaj ib txhiab meters.

Stanovoe Highlands: yam ntxwv

Lub hauv paus ntawm Stanovoy Highland yog crystalline thiab metamorphic pob zeb ntawm Archean thiab Proterozoic lub sijhawm. Intermontane kev nyuaj siab yog tsim los ntawm strata ntawm deposits ntawm lub sij hawm Cenozoic. Cov pob zeb Permafrost kuj muaj thoob plaws hauv cov toj siab.

Txoj kev daws teeb meem ntawm lub roob no txuas ntxiv mus txog niaj hnub no. Factors lees paub qhov no:siab seismic kev ua si nyob rau hauv cheeb tsam, muaj zog dissection ntawm lub nyem thiab dav permafrost zones.

Mineral resources

Zoo li lwm yam kev tsim ntawm hom no, Stanovoe Upland yog "strewn" nrog ntau hom pob zeb hauv av. Cov pob zeb loj thiab tooj liab tau pom nyob hauv Kodar Range. Copper ores yog mined ntawm Kalarsky. Kuj tseem muaj deposits ntawm kub thiab fluorite. Nyob rau hauv lub hav ntawm Chara River (Kodar Range), cov pob zeb lilac-xim av, charoite, yog mined, uas yog siv los ua cov pob zeb ornamental. Kev rho tawm ntawm cov zaub mov no yog ib qho ntawm cov haujlwm tseem ceeb ntawm kev lag luam hauv cheeb tsam no.

Climatic nta

Kev nyab xeeb ntawm thaj av no cuam tshuam los ntawm qhov siab thiab thaj chaw ntawm Stanovoy Upland. Nyob rau hauv nws cov kev txwv, ib tug sharply continental hom yog pom. Kev nyab xeeb tsuas yog sib txawv ntawm lub ncov thiab hauv cov phiab. Feem ntau, lub caij ntuj sov sov, tab sis luv luv (ntawm cov ridges nws kav ntev li ntawm 2 lub hlis, nyob rau hauv lub basins nws kav 3 lub lis piam ntev). Tab sis lub caij ntuj no nyob rau hauv cheeb tsam no yog ntev thiab txias heev. Qhov nruab nrab txhua xyoo los nag yog los ntawm 300 mm nyob rau hauv lub basins, 1000 mm ntawm lub ncov. Nws yog tsim nyog sau cia tias feem ntau ntawm lawv poob nyob rau nruab nrab Lub Xya Hli thiab Lub Yim Hli. Nyob rau hauv lub caij ntuj sov, qhov kub tsis siab tshaj +19 ° C, thiab nyob rau ntawm qhov siab ntawm 1.5 txhiab m - +13 ° C. Thaum lub caij ntuj no, tus pas ntsuas kub qhia tau tias -30 … -34 ° C. Nws yog txias dua nyob rau hauv lub hav, ntawm no daim duab no yuav poob mus rau -40 ° C.

thaj chaw ntawm qhov chaw nres tshebthaj chaw siab

Txoj kev thaj tsam

Nyob rau saum roob siab muaj cov dej khov thiab lwm yam kev pab zoo sib xws: karts, moraine ridges, trough valleys. Muaj ntau lub pas dej thiab cov dej ntws nyob rau hauv qhov kev nyuaj siab ntawm lub roob, uas tau pub los ntawm cov dej yaj.

Lub ntuj zoning ntawm Stanovoy Ridge yog tus cwj pwm los ntawm altitudinal zonality. Ntawm toj roob hauv pes thiab qhov chaw siab tshaj ntawm ridges, deciduous forests yog ntau, uas nyob rau ntawm qhov siab ntawm 1200-1600 m yog hloov los ntawm birch thiab deciduous crooked forests. Lub roob siab yog sawv cev los ntawm roob taiga, pre-bald woodlands thiab pob zeb pob zeb roob. Kev nyuaj siab Intermontane muaj dej nyab meadows, feem ntau swampy, thiab ntoo thuv thiab ntoo thuv-deciduous hav zoov loj hlob ntawm tuab sandy strata.

Yog koj saib daim duab qhia chaw uas Stanovoye Upland nyob, ces kev tswj hwm cheeb tsam no yog koom pheej ntawm Buryatia, Irkutsk thiab Chita cheeb tsam.

Siv

Thaj chaw ntawm Stanovoy Ridge tau kawm zoo heev thiab tsim kho. Rau qhov ntau dua, qhov no tau ua tiav vim qhov tshwm sim ntawm Baikal-Amur Mainline. Txoj kev hla tag nrho 7 roob toj siab ntawm toj siab. Qhov nyuaj tshaj plaws rau kev tsim kho txoj kev loj yog Severo-Muisky ridge. Kev tsim kho ntawm txoj kev tau tshwm sim tsis tu ncua rau 26 xyoo. Nyob rau hauv lub ridge, qhov ntev tshaj railway qhov nyob rau hauv lub Lavxias teb sab Federation, Severomuysky, twb tho. Nws qhov ntev yog ntau tshaj 15.3 txhiab meters. Cov chaw nres tsheb ciav hlau thiab chaw nyob tau ua rau ntawm ob sab ntawm txoj kev loj.
