Barashada ka faa'iidaysiga kala duwanaanta guriga ee xayawaanka dib loo soo celiyay ayaa muhiim u ah maaraynta dib u soo celinta xog-ogaalnimo. Lix iyo toban qof oo qaangaar ah oo Milu ah (5♂11♀) ayaa laga soo saaray Jiangsu Dafeng Milu National Nature Reserve ilaa Hunan East Dongting Lake National Nature Reserve Febraayo 28, 2016, kuwaas oo 11 Milu ah (1♂10♀) ay xirnaayeen raadraaca dayax-gacmeedka GPS collars. Ka dib, iyadoo la kaashanayo tignoolajiyada collar GPS, oo ay weheliso indho-indheynta dhulka, waxaan la soconay Milu-ga dib loo soo celiyay hal sano laga bilaabo Maarso 2016 ilaa Febraayo 2017. Waxaan isticmaalnay Model Dhaqdhaqaaqa Buundada Brownian ee firfircoon si loo qiyaaso tirada guriga ee 10ka ah. Milu rewilded (1♂ ♀, 1 qof dumar ah waa la tirtiray sababtoo ah qoorteedu way ka dhacday) iyo xilliyada guriga oo ah 5 dheddig Milu ah oo dib loo soo celiyay (dhammaantood la raadinayey ilaa hal sano). Heerka 95% wuxuu matalaa kala duwanaanshaha guriga, iyo 50% heerka wuxuu matalaa aagagga xudunta u ah. Kala duwanaanshaha ku meel gaadhka ah ee tusmada kala duwanaanshaha dhirta ee caadiga ah ayaa loo isticmaalay in lagu qiyaaso isbeddelada helitaanka cuntada. Waxaan sidoo kale qiyaasnay ​​isticmaalka kheyraadka ee Milu-dib-u-noqoshada annagoo xisaabinayna saamiga doorashada ee dhammaan degaannada aagagga asaasiga ah. Natiijooyinku waxay muujiyeen in: (1) wadar ahaan 52,960 hagaajin isku-dubarid ah ayaa la ururiyey; (2) inta lagu guda jiro marxaladda hore ee dib-u-soo-celinta, celceliska cabbirka kala duwanaanta guriga ee Milu-ga dib loo rogay wuxuu ahaa 17.62 ± 3.79 km²iyo celceliska aagagga xudunta u ah cabbirkoodu wuxuu ahaa 0.77 ± 0.10 km²; (3) Celceliska kala duwanaanshaha guriga sanadlaha ee deerada dheddigga waxay ahayd 26.08 ± 5.21 km²iyo celceliska aagagga xudunta u ah sanadlaha cabbirkoodu wuxuu ahaa 1.01 ± 0.14 km²marxaladda hore ee dib u soo celinta; (4) inta lagu guda jiro marxaladda hore ee dib-u-soo-celinta, kala-duwanaanta guriga iyo aagagga asaasiga ah ee Milu-ga dib loo soo celiyay ayaa si weyn u saameeyay xilliga, iyo farqiga u dhexeeya xagaaga iyo jiilaalka ayaa ahaa mid muhiim ah (kala duwanaanshaha guriga: p = 0.003; aagagga asaasiga ah: p = 0.008) ; (5) Kala duwanaanshaha guriga iyo meelaha xudunta u ah deerada dheddigga ah ee dib loo soo celiyay ee agagaarka harada Dongting xilliyo kala duwan waxay muujiyeen xiriir taban oo weyn oo lala yeesho NDVI (kala duwanaanshaha guriga: p = 0.000; aagagga asaasiga ah: p = 0.003); (6) Inta badan dheddigga dib loo soo celiyay Milu waxay muujisay doorbid sare oo dhul-beereed ah dhammaan xilliyada marka laga reebo jiilaalka, marka ay diiradda saaraan isticmaalka harada iyo xeebta. Kala duwanaanshaha guriga ee Milu ee dib loo soo celiyay ee agagaarka harada Dongting marxaladdii hore ee dib-u-soo-celinta waxay la kulmeen isbeddello xilliyeed oo weyn. Daraasaddeenu waxay daaha ka qaadaysaa kala duwanaanshaha xilliyeed ee kala duwanaanshaha guriga ee Milu dib loo soo celiyay iyo istiraatijiyadaha isticmaalka kheyraadka ee Milu shakhsi ahaaneed ee ka jawaabaya isbeddellada xilliyeed. Ugu dambayntii, waxaanu soo jeedinay talooyinka maamulka ee soo socda: (1) in la dhiso jasiirado deegaan; (2) si loo hirgeliyo maamul-wadaaga bulshada; (3) in la yareeyo qaska aadanaha; (4) in la xoojiyo la socodka dadweynaha ee samaynta qorshayaasha ilaalinta noocyada.
