Nqe lus piav txog kev nyiam

Geological natural monument "Geological outcrops ntawm Devonian thiab Ordovician pob zeb ntawm Saba Dej" tau teeb tsa xyoo 1976. Nws nyob 3 km ntawm lub zos Osmino, ze rau lub zos Psoed. Thaj chaw ntawm thaj chaw geological yog 650 hectares.

Ib puag ncig ntawm lub ntuj monument tau teeb tsa txhawm rau tiv thaiv qhov tawg ntawm cov pob zeb geological ntawm Ordovician thiab Devonian hnub nyoog nyob rau hnub nruab hnub, ntxiv rau khaws cov seem ntawm cov ntses plhaub hauv Devonian sediments.

Kev nqis peev txaus nyiam ntawm qhov tshwj tseg yog pom tseeb. Lub monument ntuj no tuaj yeem yog qhov zoo rau kev npaj taug kev hauv thaj chaw muaj kev tiv thaiv ntawm thaj tsam Luga thiab Gatchina.

Lub hav ntawm Saba Dej ntawm qhov chaw, uas pib ob kilometers saum toj no lub zos Psoed thiab xaus ntawm 3.5 kilometers hauv qab lub zos Osmino, muaj qhov cuam tshuam zoo li tus kheej. Lub hav yog qhov dav 250-300 m. Qhov dav ntawm tus dej channel yog 20-25 m thiab muaj qhov tob ntawm 0, 3-1, 5 m. Cov dej ntws tau nyob ntsiag to, zoo ib yam rau cov tiaj tiaj tus dej ntawm Lavxias North-West. Lub hav muaj ib qho kev taw qhia submeridional los ntawm sab qab teb mus rau sab qaum teb. Tus dej pw meanders nyob hauv ib lub hav ncaj. Qhov twg ntawm cov ntug dej hiav txwv tau raug ntxuav tawm, cov xuab zeb liab ntawm Devonian hnub nyoog tshwm sim rau hnub saum npoo av; lawv muaj cov ntxhia tseem tshuav thiab cov ntawv fossil armored ntses.

Kev tshwm sim dav dav ntawm cov txheej txheej yog nyob ze rau kab rov tav, hauv qee lub qab ntuj muaj qhov pom meej oblique txaj. Cov av tawm tuaj saum cov ntug dej los ntawm 1-6 m, qee zaum 12-15 m. Qhov ntev ntawm cov hav cuam tshuam los ntawm ob peb metres mus rau ntau pua meters (hauv qee thaj chaw). Cov zaub ntawm no raug cuam tshuam loj heev vim yog kev ua lag luam, uas yog qhov txiaj ntsig ntawm kev txhim kho thaj chaw no los ntawm tib neeg thiab nyob ze ntawm kev sib hais haum. Cov kab mob anthropogenic ntawm cov nroj tsuag tau qhia nyob rau hauv kev rhuav tshem hav zoov, feem ntau yog nyob ze qhov chaw nyob, kev sib kis ntawm thaj chaw, hluav taws kub, kev puas tsuaj ntawm qhov chaw qis, plowing thaj tsam ib puag ncig ntawm ntug dej ntawm tus dej, tsuj taw. Ntawm ntug dej Saba, muaj thaj tsam hav zoov me me-nplooj ntoo txi txiv, lawv tau tsim los ntawm cov pob tsuas, tshwj xeeb, nyob ib puag ncig Osmino.

Ntawm cov ntoo ntoo dav dav, feem ntau elm ntxhib feem ntau pom ntawm no, uas nce mus txog qhov siab tsawg kawg 15 m, ntoo tshauv, cov ntoo zoo nkauj, ntoo qhib, linden, maple kuj tau sau tseg. Hauv cov ntoo ntsuab-tsob ntoo txheej ntoo, cov tsiaj txhu tseem ceeb yog cov cuam tshuam nrog cov ntoo ntoo dav. Ntawm lawv yog bluegrass, ntoo qhib bluegrass, daj zelenchuk, ntoo qhib starweed, lanceolate stellate, txiv neej ntsias, lily ntawm hav, peach-leaved bellflower, thiab lwm yam Pine hav zoov tau sawv cev los ntawm meadow ntoo thuv hav zoov rov qab tom qab hluav taws. Ib feem ntawm lily ntawm hav hav ntoo thuv kuj tau sau tseg. Cov hav zoov me me yog sawv cev los ntawm hav zoov alder grey.

Feem ntau ntawm thaj chaw ntawm lub ntuj monument yog nyob ntawm meadows. Tsob ntoo me me loj hlob ntawm qhov chaw tua hluav taws suav nrog roob kab, miv paw, teb clover, nplaum nplaum, heather sedge, teb toad. Ntawm sab laug ntawm Saba, ze rau lub zos Psoed, nyob rau qhov chaw cuam tshuam los ntawm hluav taws, meadows nrog ntau heather tau sau tseg. Nyob rau ntawm cov tiaj nyom qhuav no tsis yog ib qho yooj yim: lichen mos lwj mos lwj thiab hav txwv yeem los ntawm cov genus Cladonia. Hauv qhov chaw ntub nruab nrab - meadows nrog lub tswb nrov, dub mullein, oregano thiab lwm yam. Hauv thaj chaw uas muaj av noo ntau, nyob ze ntawm ntug dej, muaj cov tiaj nyom siab, nyob qhov twg Veronica tso ntev, Angelica officinalis, Basilis daj, Sivets teb thiab lwm yam muaj nyob. Ntawm lub tiaj nyom uas tau cog ua ntej, uas tam sim no tau hloov pauv mus rau hauv cov hav nyom, nrog rau cov nyom nyom, kua qaub sorrel loj hlob, nyom nyom, St. John's wort.

Nyob ib ncig ntawm Osmino, muaj cov tsiaj tsis tshua muaj tsiaj ntawm tsev muag tshuaj agaric. Ib qho ntxiv, ntawm qhov tsis muaj neeg coob, cov ntug dej ntub dej ntawm tus dej, muaj cov nyiaj npib zoo li loosestrife, nkag mus buttercup, thiab amphibian mint. Cov dej hauv hav dej thiab cov dej hauv dej tau sawv cev los ntawm cov hav horsetail, cov xub xub pom, cov nplooj ntoo ntsuab daj, cov paj ntoo, cov pas dej loj, lub pas dej loj, cov txiv neej loj, txiv ntseej daj, lub tiaj nyom ncaj, meadowsweet thiab liab qab meadowsweet, kuj tseem muaj cov me me thiab coral deerweed ntev -leaved, ib hom tsiaj uas tsis tshua muaj daim npog dav dav.

Ntawm thaj chaw ntawm lub ntuj monument, cov hauv qab no tau raug tshwj xeeb tshaj yog tiv thaiv: kev tawg ntawm Devonian lub sijhawm, cov pob txha tseem tshuav ntawm cov nroj tsuag, tsiaj txhu, cov tsiaj tsis tshua muaj nroj tsuag: cov nyom txiv hmab, roob kab, Finnish pos. Kev tsim kho, kev ua haujlwm tsuas thiab rov ua haujlwm, tso ib qho kev sib txuas lus, plowing av, pov tseg ib puag ncig yog txwv tsis pub nyob ntawm no.
