Barashada ka faa'iidaysiga kala duwan ee 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 Reserve 28-kii Febraayo, 2016, kuwaas oo 11 Milu ah (1♂10♀) ay xirnaayeen qalabka GPS-ka ee raadraaca dayax-gacmeedka. Ka dib, iyada oo la kaashanayo tikniyoolajiyadda collar GPS, oo ay weheliso indho-indheynta dhulka, waxaanu raadinay Milu dib loo soo celiyay hal sano laga bilaabo March 2016 ilaa Febraayo 2017. Waxaan isticmaalnay Dhaqdhaqaaqa Dhaqdhaqaaqa Buundada Brownian Model si loo qiyaaso qiyaasta guriga ee 10 ee Milu dib loo soo celiyay (1♂9♀) (1♂9♀) Milu oo dumar 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-jiidashada annagoo xisaabinayna saamiga xulashada dhammaan degaannada aagagga xudunta u ah. Natiijooyinka waxay muujiyeen in: (1) wadarta 52,960 hagaajin isku-dubarid ah ayaa la ururiyay; (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-soocidda 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 duwanaanta guriga: p = 0.003; meelaha 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.
