Cov qauv kev tsiv teb tsaws caij caij nplooj ntoos hlav, kev siv chaw nyob, thiab chaw nres tsheb tiv thaiv qhov xwm txheej rau ob hom kab noog dej poob qis hauv Suav teb raws li qhia los ntawm satellite nrhiav.

Abstract:

East Asian migratory waterfowl tau poob qis heev txij li xyoo 1950, tshwj xeeb tshaj yog cov neeg nyob rau lub caij ntuj no hauv Suav teb. Kev txuag tau cuam tshuam loj heev los ntawm qhov tsis muaj cov ntaub ntawv tseem ceeb txog kev tsiv teb tsaws chaw thiab chaw nres tsheb. Txoj kev tshawb no siv cov txuj ci tshawb nrhiav satellite thiab kev tshuaj ntsuam xyuas spatial los tshawb xyuas lub caij nplooj ntoos hlav migration ntawm ntau dua dawb-fronted goose (Anser albifrons) thiab tundra taum goose (Anser serrirostris) lub caij ntuj no nyob rau ntawm Yangtze River Floodplain. Raws li 24 txoj kev tau txais los ntawm 21 tus neeg thaum lub caij nplooj ntoo hlav xyoo 2015 thiab 2016, peb pom tias Northeast Tuam Tshoj Plain yog qhov deb-tawm qhov chaw nres tsheb ntau tshaj plaws thaum tsiv teb tsaws, nrog cov geese nyob ntev dua 1 lub hlis. Cov cheeb tsam no kuj tau tsim kho kom zoo rau kev ua liaj ua teb, qhia txog kev sib txuas ua rau kev poob qis hauv East Asian waterfowl wintering hauv Suav teb. Kev tiv thaiv ntawm waterbodies siv raws li roosting cheeb tsam, tshwj xeeb tshaj yog cov nyob ib puag ncig los ntawm intensive foraging av, yog ib qho tseem ceeb rau waterfowl ciaj sia taus. Ntau tshaj 90% ntawm qhov chaw tseem ceeb siv thaum lub caij nplooj ntoos hlav tsiv teb tsaws tsis muaj kev tiv thaiv. Peb xav hais tias yav tom ntej hauv av yuav tsum tsom rau cov cheeb tsam no kom paub meej tias lawv muaj feem cuam tshuam rau cov neeg tsiv teb tsaws chaw ntawm cov pej xeem, thiab qhov chaw tseem ceeb roosting ntawm qhov chaw tseem ceeb caij nplooj ntoos hlav yuav tsum tau koom ua ke hauv kev sib koom ua ke ntawm thaj chaw tiv thaiv raws txoj kev ya. Tsis tas li ntawd, qhov muaj peev xwm noog-tib neeg tsis sib haum xeeb hauv qhov chaw nres tsheb tseem ceeb yuav tsum tau kawm ntxiv. Peb txoj kev tshawb fawb qhia tau hais tias yuav ua li cas satellite taug qab ua ke nrog spatial analyses tuaj yeem muab kev nkag siab tseem ceeb uas tsim nyog los txhim kho kev txuag ntawm cov tsiaj Migratory poob qis.
