Isishwankathelo:
Ukuze sazi iinkcukacha zokukhethwa kweendawo zokuhlala kunye noluhlu lwamakhaya eekhreyini ezimnyama (iGrus nigricollis) kunye nendlela ukutya imfuyo okuzichaphazela ngayo, sibone amalungu amancinci oluntu elandela umkhondo wesathelayithi kwindawo emanzi yaseDanghe yeYanchiwan National Nature Reserve eGansu ukususela ngo-2018 ukuya ku-2020 ngexesha leenyanga zikaJulayi-Agasti. Ukubeka iliso kubemi nako kwenziwa ngexesha elifanayo. Uluhlu lwamakhaya lwalinganiswa ngeendlela zokulinganisa uxinano lweekernel. Emva koko, sasebenzisa ukutolikwa komfanekiso okude kunye nokufunda koomatshini ukuchonga iintlobo ezahlukeneyo zokuhlala kwindawo emanzi yaseDanghe. Umlinganiselo wokukhetha weManly kunye nemodeli yehlathi engacwangciswanga zasetyenziswa ukuvavanya ukhetho lweendawo zokuhlala kwinqanaba leendawo zokuhlala kunye noluhlu lweendawo zokuhlala. Kwindawo yophando, umgaqo-nkqubo wokunciphisa ukutya imfuyo waqaliswa ngo-2019, kwaye impendulo yeekhreyini ezimnyama ibonisa oku kulandelayo: a) inani leekreyini ezincinci landa ukusuka kwi-23 ukuya kwi-50, nto leyo ebonisa ukuba indlela yokutya ichaphazela impilo yeekhreyini; b) indlela yangoku yokutyisa ayichaphazeli iindawo zokuhlala kunye nokukhethwa kweentlobo zeendawo zokuhlala, kodwa ichaphazela ukusetyenziswa kwendawo yikreyini njengoko isalathisi sokudlulela kweendawo zokuhlala yayiyi-1.39% ± 3.47% kunye ne-0.98% ± 4.15% kwiminyaka ka-2018 kunye no-2020, ngokulandelelana; c) bekukho umkhwa okhulayo ngokubanzi kumgama ophakathi wokuhamba kwemihla ngemihla kunye nesantya esikhawulezileyo sibonisa ukunyuka kwamandla okuhamba kweekreyini ezincinci, kwaye umlinganiselo weekreyini eziphazamisekileyo uba mkhulu; d) Izinto eziphazamisa abantu azinampembelelo ingako ekukhetheni indawo yokuhlala, kwaye iikreyini azichaphazeleki kangako ziindlu kunye neendlela okwangoku. Iikreyini zikhethe amachibi, kodwa ukuthelekisa uluhlu lwamakhaya kunye nokukhetha isikali seendawo zokuhlala, umgxobhozo, umlambo kunye noluhlu lweentaba akunakutyeshelwa. Ke ngoko, sikholelwa ukuba ukuqhubeka nomgaqo-nkqubo wokuthintelwa kokutyisa kuya kunceda ukunciphisa ukudlulela kweendawo zokuhlala kwaye emva koko kunciphise ukhuphiswano olukhethekileyo, kwaye emva koko kwandisa ukhuseleko lokuhamba kweekreyini ezincinci, kwaye ekugqibeleni kwandisa impilo yabantu. Ngaphezu koko, kubalulekile ukulawula imithombo yamanzi kunye nokugcina ukusasazwa okukhoyo kweendlela kunye nezakhiwo kuyo yonke indawo enamanzi.
