Abstract:
Kev kawm txog kev siv tsev ntau yam ntawm cov tsiaj rewilded yog qhov tseem ceeb rau kev paub txog kev tswj xyuas rov qab. Kaum rau Milu cov neeg laus (5♂11♀) tau rov qab los ntawm Jiangsu Dafeng Milu National Nature Reserve mus rau Hunan East Dongting Lake National Nature Reserve thaum Lub Ob Hlis 28, 2016, tawm ntawm 11 Milu cov tib neeg (1♂10♀) tau hnav GPS satellite taug qab dab tshos. Tom qab ntawd, nrog kev pab ntawm GPS dab tshos technology, ua ke nrog kev soj ntsuam hauv av, peb tau taug qab qhov rov qab qhia Milu rau ib xyoos txij li lub Peb Hlis 2016 txog Lub Ob Hlis 2017. Peb tau siv lub zog Brownian Choj Movement Model los kwv yees tus neeg hauv tsev ntau ntawm 10. rewilded Milu (1♂9♀, 1 tus poj niam raug tshem tawm vim nws lub dab tshos poob) thiab lub caij nyoog hauv tsev ntau ntawm 5 rewilded poj niam Milu (tag nrho cov taug qab mus txog ib xyoos). 95% theem sawv cev rau lub tsev ntau, thiab 50% theem sawv cev rau thaj chaw tseem ceeb. Kev hloov pauv mus ib ntus hauv qhov ntsuas qhov sib txawv ntawm cov nroj tsuag tau siv los ntsuas qhov kev hloov pauv hauv cov zaub mov muaj. Peb kuj tau txheeb xyuas cov peev txheej siv cov khoom siv rov ua dua tshiab Milu los ntawm kev suav cov kev xaiv piv rau txhua qhov chaw nyob hauv lawv qhov chaw tseem ceeb. Cov txiaj ntsig tau pom tias: (1) tag nrho ntawm 52,960 kev sib koom tes kho tau raug sau; (2) thaum lub sij hawm thaum ntxov ntawm rewilding, qhov nruab nrab lub tsev ntau qhov loj ntawm rewilded Milu yog 17.62 ± 3.79 km2thiab qhov nruab nrab core cheeb tsam yog 0.77 ± 0.10 km2; (3) Qhov nruab nrab txhua xyoo hauv tsev ntau qhov loj ntawm cov poj niam mos lwj yog 26.08 ± 5.21 km2thiab qhov nruab nrab ntawm cov tub ntxhais txhua xyoo yog 1.01 ± 0.14 km2thaum ntxov ntawm rewilding; (4) Thaum lub sij hawm thaum ntxov ntawm rewilding, lub tsev ntau thiab cov cheeb tsam tseem ceeb ntawm rewilded Milu tau cuam tshuam los ntawm lub caij, thiab qhov txawv ntawm lub caij ntuj sov thiab lub caij ntuj no yog qhov tseem ceeb (tsev ntau: p = 0.003; core cheeb tsam: p = 0.008) ; (5) Cov chaw hauv tsev thiab cov chaw tseem ceeb ntawm cov menyuam mos lwj nyob hauv cheeb tsam Dongting Lake hauv cov caij sib txawv tau pom muaj qhov cuam tshuam tsis zoo nrog NDVI (tsev ntau: p = 0.000; cov cheeb tsam tseem ceeb: p = 0.003); (6) Feem ntau cov poj niam rewilded Milu tau pom tias muaj kev nyiam ua liaj ua teb hauv txhua lub caij tshwj tsis yog lub caij ntuj no, thaum lawv tsom mus rau kev siv pas dej thiab puam. Lub tsev ntau yam ntawm Milu rewilded nyob rau hauv cheeb tsam Dongting Lake thaum ntxov ntawm rewilding muaj kev hloov pauv raws caij nyoog. Peb txoj kev tshawb fawb qhia txog qhov sib txawv raws caij nyoog nyob rau hauv tsev ntau yam ntawm rewilded Milu thiab cov tswv yim siv peev txheej ntawm tus neeg Milu teb rau cov kev hloov raws caij nyoog. Thaum kawg, peb muab cov lus qhia txog kev tswj hwm hauv qab no: (1) tsim kom muaj cov chaw nyob; (2) ua kom muaj kev sib koom tes hauv zej zog; (3) kom txo tau kev ntxhov siab ntawm tib neeg; (4) ntxiv dag zog rau kev saib xyuas pej xeem los tsim cov phiaj xwm kev txuag tsiaj.
