大熊猫国家公园秦岭片区生境质量时空变化特征研究
Spatio-Temporal Variation of Habitat Quality of the Giant Panda National Park in the Qinling Area,China
摘要
Abstract
Habitat quality,as a crucial indicator of ecosystem service functions,has attracted widespread at-tention globally.The Qinling area of the Giant Panda National Park is an important nature reserve in China and plays a vital role in maintaining ecological balance.This paper analyzed the land-use information of the area from 2000 to 2020.Based on the InVEST3.12.0 model,its habitat quality was assessed,and its spatio-temporal characteristics were analyzed according to the land use changes.The results showed that 1)in the Qinling area of the park,woodland,grassland,and cultivated land were the dominant types,accounting for approximately 76％,20％,and 2.2％of the total,respectively.The variations of the land use in the area were generally gentle.2)The habitat quality was spatially lower in the east and higher in the west.In 2000,2005,2010,2015,and 2020,the related indices of habitat quality were 0.912 1,0.912 7,0.914 3,0.914 2,and 0.913 5,respectively,with an initial increase followed by a subsequent decrease trend.Hotspots and cold spots of habitat quality changes concentrated mainly in the eastern area,with the hot spots particularly pronounced.3)Habitat quality was directly influenced by land use,the contribution rate of returning cultivated land to woodland and grassland was 0.055％.This study can provide a reference for ecological conservation and habitat restoration in the Qinling area of the Giant Panda National Park.关键词
