Abstract:

Kev hloov pauv huab cua tau dhau los ua ib qho tseem ceeb ua rau poob ntawm cov noog nyob thiab kev hloov pauv ntawm cov noog tsiv teb tsaws thiab kev loj hlob. Cov goose tsawg-ntev dawb (Anser erythropus) muaj ntau hom kev tsiv teb tsaws chaw thiab tau teev tseg raws li qhov tsis zoo ntawm IUCN (International Union for Conservation of Nature) Red List. Nyob rau hauv txoj kev tshawb no, qhov kev faib tawm ntawm qhov chaw yug me nyuam tsim nyog rau cov qe dawb-ntoo-ntoo tau raug soj ntsuam hauv Siberia, Russia, siv kev sib xyaw ntawm satellite taug qab thiab cov ntaub ntawv hloov pauv huab cua. Cov yam ntxwv ntawm kev faib cov chaw yug me nyuam tsim nyog nyob rau hauv cov xwm txheej huab cua sib txawv yav tom ntej tau kwv yees siv cov qauv Maxent, thiab kev tiv thaiv qhov sib txawv tau soj ntsuam. Kev tsom xam pom tau tias nyob rau hauv keeb kwm yav dhau los ntawm kev hloov pauv huab cua yav tom ntej, qhov kub thiab nag lossis daus yuav yog qhov tseem ceeb ntawm huab cua cuam tshuam rau kev faib cov chaw yug me nyuam, thiab thaj chaw cuam tshuam nrog cov chaw yug me nyuam uas tsim nyog yuav nthuav tawm qhov kev poob qis. Cov cheeb tsam tau teev tseg raws li qhov chaw nyob zoo tsuas yog suav txog 3.22% ntawm kev tiv thaiv kev faib tawm; Txawm li cas los xij, 1,029,386.341 km²pom thaj chaw zoo tshaj plaws nyob sab nraum thaj chaw tiv thaiv. Tau txais cov ntaub ntawv faib cov tsiaj yog ib qho tseem ceeb rau kev tsim kev tiv thaiv thaj chaw nyob hauv thaj chaw deb. Cov txiaj ntsig tau nthuav tawm ntawm no tuaj yeem muab lub hauv paus rau kev tsim cov hom phiaj kev tswj hwm thaj chaw tshwj xeeb thiab qhia tias yuav tsum tau saib xyuas ntxiv rau kev tiv thaiv qhov chaw qhib.
