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 yekuronda collar. Zvadaro, nerubatsiro rweGPS collar tekinoroji, yakasanganiswa ne-on-ground tracking observations, takatsvaga Milu yakadzokororwa kwegore rimwe kubva munaKurume 2016 kusvika Kukadzi 2017. Takashandisa iyo dynamic Brownian Bridge Movement Model kuti tifungidzire imba yega yega yegumi yakadzokororwa Milu (1♂9♀) yakadonha kubva mumwaka we5 wevakadzi rewilded mukadzi Milu (ese akateedzerwa kusvika gore rimwe). 95% nhanho inomiririra imba, uye 50% nhanho inomiririra nzvimbo dzepakati. Musiyano wenguva mune yakajairwa musiyano wezvinomera index wakashandiswa kuyera shanduko mukuwanikwa kwechikafu. Isu takaongororawo kushandiswa kwezviwanikwa kweMilu yakadzokororwa nekuverenga chiyero chekusarudza kune ese ekugara mukati menzvimbo dzadzo dzepakati. Mhedzisiro yacho yakaratidza kuti: (1) huwandu hwe52,960 kuronga kugadzirisa kwakaunganidzwa; (2) panguva yekutanga danho rekugadzirisa, 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 kwekugadzirisa zvakare, nzvimbo yeimba uye nzvimbo dzakakosha dzeMilu yakadzorerwa zvakakanganiswa zvikuru 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 vainangana nekushandisa dziva nemahombekombe. Imba yemusha yeMilu yakadzokororwa munzvimbo yeDongting Lake panguva yekutanga yekudzokorodza yakasangana nekuchinja kwemwaka. 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.
