Kufufuza kwa kagwiritsidwe ntchito ka mitundu ya ziweto zolusa n'kofunika kwambiri pa kasamalidwe ka kubwezeretsedwa kodziwa bwino. Anthu achikulire 16 a Milu (5♂11♀) adatsitsimutsidwa kuchokera ku Jiangsu Dafeng Milu National Nature Reserve kupita ku Hunan East Dongting Lake National Nature Reserve pa February 28, 2016, pomwe anthu 11 a Milu (1♂10♀) anali atavala GPS satellite tracking. makolala. Pambuyo pake, mothandizidwa ndi teknoloji ya GPS ya kolala, kuphatikizapo kuyang'ana pamtunda, tinatsata Milu yomwe inayambikanso kwa chaka chimodzi kuyambira March 2016 mpaka February 2017. rewilded Milu (1♂9♀, 1 wamkazi adachotsedwa chifukwa kolala yake idagwa) komanso nyumba zosiyanasiyana za Milu 5 zachikazi (zonse zidatsatiridwa mpaka chaka chimodzi). Mulingo wa 95% umayimira mtundu wakunyumba, ndipo 50% idayimira madera oyambira. Kusintha kwakanthawi mu index yokhazikika ya zomera kunagwiritsidwa ntchito kuwerengera kusintha kwa kupezeka kwa chakudya. Tidawerengeranso kugwiritsa ntchito zida za Milu yosinthidwa powerengera kuchuluka kwa malo omwe amakhala m'malo awo oyambira. Zotsatira zinasonyeza kuti: (1) chiwerengero cha 52,960 chokonzekera chogwirizanitsa chinasonkhanitsidwa; (2) Kumayambiriro kwa kukonzanso, kukula kwapakati pa nyumba ya Milu yomwe idasinthidwa inali 17.62 ± 3.79 km.2ndipo pafupifupi madera apakati kukula kwake kunali 0.77 ± 0.10 km2; (3) kukula kwapachaka kwa mbawala yaikazi inali 26.08 ± 5.21 km2ndipo kukula kwapakati pazaka zapakati kunali 1.01 ± 0.14 km2pa chiyambi cha kusintha kwa thupi; (4) kumayambiriro kwa kukonzanso, malo amtundu wa nyumba ndi madera apakati a Milu yomwe inagwiritsidwanso ntchito inakhudzidwa kwambiri ndi nyengo, ndipo kusiyana pakati pa chilimwe ndi nyengo yozizira kunali kwakukulu (kunyumba: p = 0.003; madera oyambirira: p = 0.008) ; (5) malo okhala ndi malo oyambira agwape aakazi omwe adasungidwanso m'dera la Dongting Lake munyengo zosiyanasiyana adawonetsa kusagwirizana kwakukulu ndi NDVI (kunyumba: p = 0.000; madera oyambira: p = 0.003); (6) Azimayi ambiri a Milu omwe adasamutsidwanso adawonetsa kukonda kwambiri minda m'nyengo zonse kupatula nyengo yachisanu, pomwe amaganizira kwambiri kugwiritsa ntchito nyanja ndi gombe. Kunyumba kwa Milu yomwe idasinthidwanso m'dera la Dongting Lake koyambirira kokonzanso zidasintha kwambiri nyengo. Kafukufuku wathu akuwonetsa kusiyana kwa nyengo m'manyumba a Milu yosinthidwanso komanso njira zogwiritsira ntchito zida za Milu payekha potengera kusintha kwa nyengo. Potsirizira pake, tinapereka malingaliro otsogolera otsatirawa: (1) kukhazikitsa zilumba zokhalamo; (2) kukhazikitsa kasamalidwe ka anthu ammudzi; (3) kuchepetsa kusokonezeka kwa anthu; (4) kulimbikitsa kalondolondo wa chiwerengero cha anthu pokonza mapulani oteteza zachilengedwe.
