Izinhlobo (Izinyoni):I-Swan goese (Anser cygnoides)
Ijenali:Ukuzwa Kukude
Abstract:
Izindawo zokuhlala zinikeza indawo ebalulekile ukuze izinyoni ezifudukayo ziphile futhi zizalane. Ukuhlonza izindawo zokuhlala ezingaba khona ezigabeni zomjikelezo waminyaka yonke kanye nezici zazo ezinomthelela kubalulekile ekulondolozweni endleleni yendiza. Kulolu cwaningo, sithole ukulandelelwa ngesathelayithi kwamahansi ayisishiyagalombili (Anser cygnoides) asebusika e-Poyang Lake (28°57′4.2″, 116°21′53.36″) kusukela ngo-2019 kuya ku-2020. Sisebenzisa imodeli yokusabalalisa yezinhlobo ze-Maximum Entropy, siphenye. ukusatshalaliswa kwezindawo okungaba khona kwamahansi phakathi nomjikelezo wawo wokufuduka. Sihlaziye iqhaza elihlobene lezinto ezihlukahlukene zemvelo ekufanelekeni kwendawo yokuhlala kanye nesimo sokongiwa kwendawo ngayinye engase ibe khona emgwaqeni ondizayo. Imiphumela yethu ibonisa ukuthi izindawo zokuqala zasebusika zamahansi amadada zitholakala maphakathi naphansi koMfula i-Yangtze. Izindawo zokuma zasatshalaliswa kabanzi, ikakhulukazi e-Bohai Rim, indawo emaphakathi yoMfula Ophuzi, kanye neThafa elisenyakatho-mpumalanga, futhi zanwetshwa ngasentshonalanga ukuya e-Inner Mongolia naseMongolia. Izindawo ezizalela kuzo ikakhulukazi e-Inner Mongolia nasempumalanga yeMongolia, kanti ezinye zisabalele enkabeni nasentshonalanga yeMongolia. Amazinga omnikelo wezici ezinkulu zemvelo ahlukile ezindaweni zokuzalela, izindawo zokuma, nezindawo zasebusika. Izindawo ezizalela kuzo zazithonywa ukuthambeka, ukuphakama nezinga lokushisa. Umthambeka, inkomba yezinyathelo zomuntu, nezinga lokushisa kwakuyizici eziyinhloko ezathinta izindawo zokuma. Izindawo zasebusika zazinqunywa ngokusetshenziswa komhlaba, ukuphakama, kanye nemvula. Isimo sokongiwa kwezindawo zokuhlala singu-9.6% sezindawo ezizalela kuzo, u-9.2% wezindawo zasebusika, kanye no-5.3% wezindawo zokumisa. Ngakho-ke esikutholile kunikeza ukuhlolwa kwamazwe ngamazwe okubucayi kokuvikelwa kwezindawo zokuhlala ezingaba khona zezinhlobo zamahansi ku-East Asian Flyway.
