Abstract:
Ucwaningo lokusetshenziswa kwebanga lasekhaya lezilwane ezigaywe kabusha lubalulekile ekulawuleni ukwethulwa kabusha unolwazi. Abantu abadala abayishumi nesithupha bakwa-Milu (5♂11♀) baphinde baqanjwa besuka e-Jiangsu Dafeng Milu National Nature Reserve bayiswa e-Hunan East Dongting Lake National Nature Reserve ngoFebruwari 28, 2016, phakathi kwabo abantu abangu-11 Milu (1♂10♀) babegqoke amakholola okulandelela isathelayithi e-GPS. Ngokulandelayo, ngosizo lwekhola yobuchwepheshe be-GPS, kuhlanganiswe nokubonwa kokulandela ngomkhondo okuphansi, silandelele i-Milu eyethulwe kabusha unyaka owodwa kusukela ngoMashi 2016 kuya kuFebruwari 2017. Sisebenzise imodeli yeBrownian Bridge Movement eguqukayo ukuze silinganisele uhla lwasekhaya lwe-Milu (1♂9♀ ephindwe kabusha engu-10) ngenxa yokuthi isizini eyodwa yabesifazane yaqedwa, isizini yayo ngayinye yaqedwa 5 u-Milu wesifazane ovuselelwe kabusha (konke kulandelelwe isikhathi esingangonyaka owodwa). Ileveli engu-95% imele ububanzi basekhaya, futhi ileveli engu-50% imele izindawo eziyinhloko. Ukuhlukahluka kwesikhashana kunkomba yezitshalo ehlukile evamile kwasetshenziselwa ukulinganisa izinguquko ekutholakaleni kokudla. Siphinde salinganisela ukusetshenziswa kwezinsiza ze-Milu egaywe kabusha ngokubala isilinganiso sokukhetha kuzo zonke izindawo zokuhlala ezingaphakathi kwezindawo zazo eziyinhloko. Imiphumela yabonisa ukuthi: (1) kwaqoqwa inani eliphelele lama-52,960 lokulungisa; (2) ngesikhathi sokuqala sokuguqulwa, isilinganiso sosayizi webanga lekhaya le-Milu esakhiwe kabusha sasingu-17.62 ± 3.79 km2futhi usayizi wezindawo eziwumgogodla omaphakathi wawungu-0.77 ± 0.10 km2; (3) isilinganiso sonyaka sobukhulu bendlu yenyamazane yensikazi sasingu-26.08 ± 5.21 km2futhi isilinganiso sonyaka sobukhulu bezindawo eziwumgogodla sasingu-1.01 ± 0.14 km2esikhathini sokuqala sokukhulelwa; (4) phakathi nesigaba sokuqala sokuphinda kugaywe kabusha, ububanzi bekhaya nezindawo eziyinhloko ze-Milu esakhiwe kabusha zathinteka kakhulu isizini, futhi umehluko phakathi kwehlobo nobusika wawubalulekile (ibanga lasekhaya: p = 0.003; izindawo eziyinhloko: p = 0.008); (5) uhla lwasekhaya kanye nezindawo eziwumgogodla zenyamazane yezinsikazi ehlatshwe kabusha endaweni yase-Dongting Lake ngezikhathi ezihlukene zonyaka zibonise ukuhlobana okubalulekile okungekuhle ne-NDVI (ibanga lasekhaya: p = 0.000; izindawo eziwumgogodla: p = 0.003); (6) Iningi labesifazane abasakhiwe kabusha iMilu bakhombise ukuthanda kakhulu indawo yokulima kuzo zonke izinkathi zonyaka ngaphandle kwasebusika, lapho begxile ekusebenziseni ichibi nolwandle. Ibanga lasekhaya le-Milu esetshenziswe kabusha endaweni yase-Dongting Lake ekuqaleni kokulungiswa kabusha kube nezinguquko eziphawulekayo zesizini. Ucwaningo lwethu lwembula umehluko wesizini kububanzi basekhaya be-Milu ekhishwe kabusha kanye namasu okusebenzisa insiza ye-Milu ngayinye ukuphendula izinguquko zesizini. Ekugcineni, sibeka phambili izincomo zokuphatha ezilandelayo: (1) ukusungula iziqhingi ezihlala kuzo; (2) ukusebenzisa ukuphatha ngokubambisana komphakathi; (3) ukunciphisa ukuphazamiseka kwabantu; (4) ukuqinisa ukubhekwa kwenani labantu ukuze kwakhiwe izinhlelo zokongiwa kwezinhlobo zezilwane.
