土地利用和覆被变化对新疆藏羚栖息地适宜性的影响
Impacts of land use and land cover change on habitat suitability of Pan-tholops hodgsonii in Xinjiang,China
摘要
Abstract
Habitat suitability dynamics critically shape wildlife population persistence.While habitat impact factor stud-ies have accumulated substantial evidence,the specific effects of land use and land cover change(LUCC)on the poten-tial distribution of Pantholops hodgsonii remain unexplored.This study investigated habitat suitability dynamics of P.hodgsonii in Xinjiang using 247,319,and 273 validated occurrence records from 2015,2019,and 2023 surveys,respec-tively,through integrated MaxEnt modeling and land use transition matrix analysis.Key results reveal that high-suitabili-ty habitats(probability ≥ 50％)predominantly occur in high/very high elevation plains and hills(0°-8° slope),with 117-130 mm precipitation seasonality(Bio 15),and LUCC types including Gobi,swamps,mudflats,low-coverage grasslands,saline-alkali soils,and scrublands.A net expansion of 15 789 km2(+6.83％)in unsuitable habitats was observed from 2015 to 2023,paralleled by a 20.28％contraction of suitable habitats.LUCC-driven habitat class transitions accounted for 9 479 km2(16.54％of total habitat changes)during 2015-2019 and 7 499 km2(13.24％)during 2019-2023,estab-lishing LUCC as a key driver of habitat configuration shifts.By synthesizing multi-temporal field observations,this work pioneers the identification of spatiotemporal coupling mechanisms between Pantholops hodgsonii habitat suitabili-ty and LUCC variations,offering critical insights for conservation strategy optimization in alpine ecosystems.关键词
