江西桃红岭自然保护区夏季梅花鹿对生境的选择性

Summer Habitat Selection by Sika Deer in Taohongling Nature Reserve,Jiangxi Province

2005年6-8月在江西桃红岭自然保护区对夏季梅花鹿的生境选择性进行了初步研究。结果表明：梅花鹿选择灌丛和灌草丛、郁闭度较低、灌木盖度较小、食物丰富度高、阴坡、中上坡位、坡度平缓、水源距离在100-400m、人为干扰距离〉800m和海拔高度〉300m的环境；对郁闭度〉80％和水源距离≤100m的环境表现为随机选择。

Summer habitat selection by sika deer was studied adopting the selection index ＂Wi＂ and ＂Ei＂ in Taohongling Nature Reserve, Pengze County of Jiangxi Province from June to August 2005. The result indicates that the environmental factors preferred by sika deer are shrub and shrub-meadow, lesser canopy and shrub overcast, high food abundance, shade, mid and upper slope, lesser slope, water source distance from 100 to 400 m, distance from human disturbance exceeding 800 m and elevation exceeding 300 m. Canopy exceeding percent 80 and water source distance less than 100 m has lesser influence on the habitat selection by sika deer. It is suggested that it is necessary to intensify community concord and execute habitat improvement.
