森林采伐对桃红岭国家级自然保护区梅花鹿冬季生境选择的影响

Impact of Logging upon the Habitat Selection of Sika Deer in Winter in Taohongling National Nature Reserve,China

2011年和2012年的冬季在桃红岭国家级自然保护区采用随机样方法,调查了森林采伐对梅花鹿冬季生境选择的影响。调查结果表明:梅花鹿冬季在采伐迹地和非采伐区生境选择存在显著性差异。在采伐迹地,梅花鹿多在植被密度适中或稠密、覆盖度适中或较高、海拔200 m以上的生境活动;在非采伐区,梅花鹿多在植被高度低于1 m、植被密度适中、海拔400 m以上的生境活动。森林采伐后第3年梅花鹿的活动利用强度最大。

To study the impact of logging upon the habitat selection of sika deer Cervus nippon kopschi in winter,systematic sampling was used in 2011 and 2012 in Taohongling National Nature Reserve in Jiangxi province,China. The survey results revealed that there were significant differences in habitat selection between the logged and unlogged areas. In logged areas,sika deer preferred the habitat with moderate or dense vegetation density,moderate or greater coverage degree with altitude above 200 m. However,in unlogged areas,sika deer chose the vegetation height short than 1 m with moderate density and altitude was above 400 m. The maximum intensity of sika deer was observed after three years’ deforestation.
