Magazini:Kuzindikira Kwakutali
Chidule:
Malo okhala amapereka malo ofunikira kuti mbalame zosamukira zipulumuke ndi kuberekana. Kuzindikira malo okhala pachaka komanso zinthu zomwe zimakhudza mbalamezi ndikofunikira kwambiri kuti zisungidwe bwino m'njira yowulukira. Mu kafukufukuyu, tinapeza njira yowunikira atsekwe asanu ndi atatu a swan (Anser cygnoides) omwe amakhala m'nyengo yozizira ku Poyang Lake (28°57′4.2″, 116°21′53.36″) kuyambira 2019 mpaka 2020. Pogwiritsa ntchito chitsanzo cha Maximum Entropy species distribution, tinafufuza momwe atsekwe a swan amakhalira m'malo awo okhala panthawi yosamukira kwawo. Tinafufuza momwe zinthu zosiyanasiyana zachilengedwe zimathandizira kuti malo okhala azikhala oyenera komanso momwe amasungira malo okhala m'njira iliyonse yowulukira. Zotsatira zathu zikusonyeza kuti malo oyamba a atsekwe a swan amakhala m'nyengo yozizira ali pakati ndi pansi pa Mtsinje wa Yangtze. Malo oimikapo mbalame anali ambiri, makamaka ku Bohai Rim, pakati pa Mtsinje wa Yellow, ndi Northeast Plain, ndipo anafalikira kumadzulo mpaka ku Inner Mongolia ndi Mongolia. Malo oberekera makamaka ali ku Inner Mongolia ndi kum'mawa kwa Mongolia, pomwe ena ali kudera lapakati ndi lakumadzulo kwa Mongolia. Ziwerengero zazikulu za zinthu zachilengedwe zimasiyana m'malo oberekera, malo oimikapo, ndi malo oimikapo nthawi yozizira. Malo oberekera anakhudzidwa ndi malo otsetsereka, kukwera, ndi kutentha. Malo otsetsereka, chizindikiro cha mapazi a anthu, ndi kutentha ndi zinthu zazikulu zomwe zinakhudza malo oimikapo. Malo oimikapo nthawi yozizira adatsimikiziridwa ndi kagwiritsidwe ntchito ka nthaka, kukwera, ndi mvula. Mkhalidwe wosungira malo okhala ndi 9.6% m'malo oberekera, 9.2% m'malo oimikapo nthawi yozizira, ndi 5.3% m'malo oimikapo. Motero zomwe tapeza zikupereka kuwunika kwakukulu kwapadziko lonse lapansi kwa chitetezo cha malo okhala a atsekwe pa East Asian Flyway.
