Abstract:

Chidzidzo chekushandiswa kwemhando dzemba dzemhuka dzakasimudzwa zvakare kwakakosha pakutonga kudzoreredzwa neruzivo. Vanhu vakuru gumi nevatanhatu veMilu (5♂11♀) vakaunzwazve kubva kuJiangsu Dafeng Milu National Nature Reserve kuenda kuHunan East Dongting Lake National Nature Reserve musi waKukadzi 28, 2016, mukati mawo vanhu 11 Milu (1♂10♀) vanga vakapfeka GPS satellite tracking. makora. Zvadaro, nerubatsiro rwe GPS collar teknolojia, yakasanganiswa ne-on-ground tracking yekucherechedza, takatsvaga Milu yakadzoserwa kwegore rimwe kubva muna March 2016 kusvika February 2017. Takashandisa dynamic Brownian Bridge Movement Model kuti tifungidzire mararamiro ega ega e10. rewilded Milu (1♂9♀, munhu 1 wechikadzi akabviswa nekuti kora yake yakadonha) uye mwaka nemwaka wemusha weMilu wechikadzi 5 (zvese zvakarondwa kwerinosvika gore rimwe). 95% nhanho yaimiririra imba, uye 50% nhanho inomiririra nzvimbo dzepakati. Musiyano wenguva mune yakajairwa musiyano wezvinomera index wakashandiswa kuyera shanduko mukuwanikwa kwechikafu. Isu takaverengerawo kushandiswa kwezviwanikwa kweMilu yakadzokororwa nekuverenga chiyero chesarudzo chenzvimbo dzese dzekugara mukati menzvimbo dzadzo dzepakati. Mhedzisiro yacho yakaratidza kuti: (1) huwandu hwe52,960 hurongwa hwekugadzirisa hwakaunganidzwa; (2) panguva yekutanga kudzoreredza, avhareji saizi yeimba yeMilu yakadzokororwa yaive 17.62 ± 3.79 km.²uye avhareji yenzvimbo dzepakati saizi yaive 0.77 ± 0.10 km²; (3) avhareji yegore renji renji saizi yemhembwe yechikadzi yaive 26.08 ± 5.21 km²uye avhareji yepakati pepakati nzvimbo saizi yaive 1.01 ± 0.14 km²panguva yekutanga yekudzokorora; (4) panguva yekutanga kwekugadzirisazve, nzvimbo yeimba uye nzvimbo dzepakati dzeMilu yakadzokororwa zvakakanganiswa zvakanyanya nemwaka, uye musiyano pakati pezhizha nechando wakanga wakakosha (imba yeimba: p = 0.003; nzvimbo dzepakati: p = 0.008) ; (5) nzvimbo yemusha uye nzvimbo dzakakosha dzehadzi yakadzokororwa munzvimbo yeDongting Lake mumwaka yakasiyana yakaratidza kuwirirana kwakashata neNDVI (imba yeimba: p = 0.000; nzvimbo dzepakati: p = 0.003); (6) Milu yechikadzi yakadzokororwa yakaratidza kufarira kwakakwirira minda yekurima mumwaka yese kunze kwechando, apo vaitarisa kushandisa dziva nemahombekombe. Imba yemusha yeMilu yakadzokororwa munzvimbo yeDongting Lake padanho rekutanga rekugadzirisa zvakare yakawana shanduko yemwaka. Chidzidzo chedu chinoburitsa misiyano yemwaka mumisiyano yemba yeMilu yakadzokororwa uye nzira dzekushandisa zviwanikwa zveMilu mumwe nemumwe mukupindura shanduko yemwaka. Pakupedzisira, tinoisa mberi kunotevera kurudziro yokutarisira: (1) kutanga zvitsuwa zvinogara; (2) kushandisa hutungamiri hwemunharaunda; (3) kuderedza kuvhiringidzika kwevanhu; (4) kusimbisa kutariswa kwevanhu pakugadzira zvirongwa zvekuchengetedza mhuka.
