Isishwankathelo:
Uphononongo lokusetyenziswa kwezilwanyana ezihlaziyiweyo kwiindawo zasekhaya lubalulekile kulawulo lokubuyiselwa kwezilwanyana. Izilwanyana ezindala ezilishumi elinesithandathu zeMilu (5♂11♀) zabuyiselwa kwiJiangsu Dafeng Milu National Nature Reserve ukuya kwiHunan East Dongting Lake National Nature Reserve nge-28 kaFebruwari 2016, apho i-11 yeMilu (1♂10♀) yayinxibe iikhola zokulandelela i-GPS satellite. Emva koko, ngoncedo lwetekhnoloji yekhola yeGPS, kunye nokujongwa kokulandelela emhlabeni, salandela iMilu ehlaziyiweyo indawo unyaka omnye ukususela ngoMatshi 2016 ukuya kuFebruwari 2017. Sisebenzise iBrownian Bridge Movement Model enamandla ukuqikelela uluhlu lwezindlu nganye ye-10 yeMilu ehlaziyiweyo (1♂9♀, ibhinqa eli-1 lasuswa ngenxa yokuba ikhola yalo yawa) kunye noluhlu lwezindlu lwamaxesha athile lwe-5 yeMilu ehlaziyiweyo indawo zasekhaya (zonke zilandelwa ukuya kuthi ga kunyaka omnye). Inqanaba lama-95% limele uluhlu lwezindlu, kwaye inqanaba lama-50% limele iindawo eziphambili. Utshintsho lwexeshana kwi-normalized difference vegetables index lusetyenzisiwe ukulinganisa utshintsho ekufumanekeni kokutya. Sikwalinganise ukusetyenziswa kwezixhobo ze-rewilded Milu ngokubala umlinganiselo wokukhetha kuzo zonke iindawo zokuhlala kwiindawo zazo eziphambili. Iziphumo zibonise ukuba: (1) kuqokelelwe izilungiso ezingama-52,960; (2) ngexesha lokuqala lokuphinda kuhlalwe, ubungakanani obuqhelekileyo bekhaya le-rewilded Milu yayiyi-17.62 ± 3.79 km.2kwaye ubungakanani obuphakathi beendawo eziphambili yayiyi-0.77 ± 0.10 km2(3) ubungakanani bonyaka bendlu yeenyamakazi ezihlala kuyo yayiyi-26.08 ± 5.21 km2kwaye ubungakanani obuphakathi beendawo eziphambili ngonyaka yayiyi-1.01 ± 0.14 km2ekuqaleni kokuphinda kutshalwe kwakhona; (4) ngexesha lokuqala kokuphinda kutshalwe kwakhona, iindawo zasekhaya kunye neendawo eziphambili zeMilu ephinde yatshalwa kwakhona zachaphazeleka kakhulu lixesha lonyaka, kwaye umahluko phakathi kwehlobo nobusika wawubalulekile (uluhlu lwasekhaya: p = 0.003; iindawo eziphambili: p = 0.008); (5) iindawo zasekhaya kunye neendawo eziphambili zeenyamakazi eziphinde zatshalwa kwakhona kwindawo yaseDongting Lake ngamaxesha ahlukeneyo onyaka zibonise unxibelelwano olubi olukhulu ne-NDVI (uluhlu lwasekhaya: p = 0.000; iindawo eziphambili: p = 0.003); (6) Uninzi lweemazi zeMilu eziphinde zatshalwa kwakhona zibonise ukukhetha okuphezulu kwiindawo zasefama kuzo zonke iimeko zonyaka ngaphandle kobusika, xa zigxile ekusebenziseni ichibi nolwandle. Iindawo zasekhaya zeMilu ephinde yatshalwa kwakhona kwindawo yaseDongting Lake ekuqaleni kokuphinda kutshalwe kwakhona zafumana utshintsho olukhulu lonyaka. Uphononongo lwethu lubonisa umahluko wonyaka kwiindawo zasekhaya zeMilu ephinde yatshalwa kwakhona kunye namaqhinga okusebenzisa izixhobo zeMilu nganye ukuphendula utshintsho lonyaka. Ekugqibeleni, sinikezele ngezi ngcebiso zilandelayo zolawulo: (1) ukuseka iziqithi zokuhlala; (2) ukuphumeza ulawulo oluhlangeneyo loluntu; (3) ukunciphisa ukuphazamiseka kwabantu; (4) ukuqinisa ukubekwa esweni koluntu ukuze kuqulunqwe izicwangciso zokulondolozwa kweentlobo ngeentlobo.
