Sab Hnub Poob Siberian Plain yog ib thaj av loj tshaj plaws hauv ntiaj teb. Los ntawm sab qaum teb mus rau sab qab teb, nws stretches rau ob thiab ib nrab txhiab kilometers, los ntawm sab hnub poob mus rau sab hnub tuaj - tsawg tshaj li ob txhiab. Nws thaj tsam thaj tsam yog: nyob rau sab qaum teb - hiav txwv Arctic hiav txwv, nyob rau hauv sab qab teb - lub Kazakh toj, nyob rau hauv sab hnub poob - lub Urals thiab nyob rau hauv sab hnub tuaj - lub Yenisei. Thaj chaw ntawm lub tiaj yog me ntsis tsawg dua peb lab square kilometers.

Muaj ntau qhov tso nyiaj ntawm ntau yam minerals ntawm no. Tab sis qhov tseem ceeb yog hydrocarbons. West Siberian Plain yog thaj av loj tshaj plaws ntawm cov roj thiab roj cov kabmob ntawm Lavxias Federation thiab ib qho loj tshaj plaws hauv ntiaj teb.

Thaj chaw loj thiab cov txheeb ze sib xws ntawm kev nyem tau ua rau Sab Hnub Poob Siberian Plain suav nrog ntau thaj chaw ntuj thiab huab cua nrog kev faib tawm ntawm sab qaum teb mus rau sab qab teb. Hauv thaj chawNyob ib sab ntawm Arctic Dej hiav txwv, qhov tseem ceeb ntawm toj roob hauv pes yog tundra nrog cov av ntub dej. Nyob rau sab qab teb, tus cwj pwm ntawm struts yog maj hloov. Lub tundra yog hloov los ntawm hav zoov-tundra nrog Islands tuaj ntawm cov ntoo qis, mus rau sab qab teb - taiga, muaj cov ntoo coniferous tsaus, thiab ntxiv rau sab qab teb yog txoj siv ntawm cov hav zoov deciduous. Nyob rau ntawm tsib caug-tsib piv, cov hav zoov tau diluted nrog steppe thiab teb, thiab yuav luag tsis muaj hav zoov ntawm ciam teb nrog Kazakhstan, tshwj tsis yog cov cheeb tsam sab hnub tuaj ntawm lub tiaj.

Nyob rau hauv lub xya caum ntawm lub xyoo pua xeem, West Siberian Plain tau raug muaj zog anthropogenic cuam tshuam. Qhov cuam tshuam txuas ntxiv mus rau hnub no. Qhov no yog vim qhov pib ntawm kev loj hlob loj ntawm hydrocarbon deposits. Tab sis txawm tias tam sim no, thaj chaw loj heev sab nraum cov chaw tso nyiaj hydrocarbon tseem nyob hauv hav zoov, raws li lawv tau ntau xyoo dhau los.

Natural conditions txawm nyob rau tib lub latitude txawv me ntsis ntawm no. Qhov no yog vim lub fact tias West Siberian Plain, uas nws kev nyab xeeb nyob ntawm lub xub ntiag ntawm ib tug tej yam ntuj tso barrier (lub Urals) uas tiv thaiv los ntawm sov westerly cua, nyob rau hauv lub cheeb tsam ntawm kev hloov ntawm ib tug temperate continental kev nyab xeeb mus rau ib tug sharply continental. ib. Thiab yog hais tias qhov sib txawv ntawm lub caij ntuj sov thiab lub caij ntuj no kub nyob rau hauv cov cheeb tsam uas nyob ib sab ntawm lub Urals yog tsawg pronounced, ces lub sab laug bank ntawm lub Yenisei twb yog ib thaj chaw uas muaj tag nrho-fledged sharply continental huab cua reigns.

Tsis muaj qhov kev nce siab loj ntawm no, tab sis tseem muaj cov toj me me, cov av qis thiab cov swamps, uas tshwj xeeb tshaj yog nplua nuj nyob rau sab hnub poob Siberian Plain. Lub nyem zoo li muaj cov ntsiab lus (Vasyugan tiaj, Kulunda ranina, Baraba lowland, thiab lwm yam), sib tw nrog ib leeg - leej twg yog qis dua. Thiab tsuas yog nyob rau sab qaum teb yog Siberian Uvals -

ib tug ridge cuaj puas kilometers, lub siab tshaj plaws taw tes uas NW nyuam qhuav tshaj peb puas meters.

Sib cais, yuav tsum hais txog cov dej ntws ntawm Sab Hnub Poob Siberian Plain. Yuav luag tag nrho cov cheeb tsam yog nyob ntawm Ob phiab nrog lub ntsiab tributary, lub Irtysh. Sab hnub tuaj ntawm lub tiaj yog suav nrog hauv Yenisei phiab. Lub cheeb tsam yog muab nrog dej nyob rau hauv abundance. Tab sis vim qhov tiaj tus ntawm tus dej thiab qhov tsis muaj kev hloov pauv ntawm qhov siab, tsis muaj qhov chaw nres tsheb loj loj ntawm nws, tshwj tsis yog Novosibirsk, nyob rau sab saud. Txawm hais tias muaj peev xwm loj, kev tsim kho ntawm qhov chaw nres tsheb hluav taws xob nyob rau ntawm Ob hauv qab Novosibirsk yog tsis yooj yim sua, vim hais tias nyob rau hauv cov ntaub ntawv no ib tug loj ib ncig ntawm yuav raug dej nyab.
