大田保护区火烧草地植被对海南坡鹿栖息地的影响

Effects of Burning Grassland Vegetation in Datian Nature Reserve on Cenvus eldi hainanus

海南坡鹿(Cenvus eldi hainanus)是中国特有的国家Ⅰ级重点保护动物。草地类型是海南坡鹿重要的生境类型,为了弄清楚火烧草地后对海南坡鹿坡鹿栖息地的影响,我们在1～10月份内采用了样地法和样线法分别从坡鹿食物量变化、外来植物覆盖度变化、坡鹿对栖息地选择的变化及其行为变化等情况进行调查,经调查发现海南坡鹿的食物量在火烧地和非火烧地内平均每月分别为953.7g/m^2和903.3g/m^2;外来植物的覆盖度在火烧地和非火烧地内平均每月分别为12.7%和7.9%;坡鹿对火烧地和非火烧地的选择分别为55.3%和44.7%;坡鹿在火烧地和非火烧地的各种行为比是:采食60.7%和39.3%;运动53.3%和46.7%;休息44.4%和55.6%。
