中文摘要：2012年4~8月，在甘肃莲花山国家级自然保护区采用无线电遥测技术并结合野外观察，对血雉春季和夏季的栖息地特征进行了比较研究。逻辑斯蒂回归分析表明，雪深度、灌木盖度和距水源距离是影响血雉春季栖息地选择的主要因子；夏季血雉以乔木数量、灌木高度和坡向作为栖息地选择的主要因子。t检验和U检验结果表明：乔木胸径、针叶树数量、灌木高度、灌木盖度、苔藓盖度、草盖度在春、夏两个季节内差异极显著，而坡向在两个季节内差异显著。
英文摘要：The habitat characteristics of blood pheasant (Ithaginis cruentus) in spring and summer were studied by radio-telemetry and field observations at Lianhuashan Nature Reserve (Gansu province) from April to August in 2012. The results of logistic regression suggested that the main habitat selection factors in spring were the height of snow, cover of shrub, distance from water, whereas the number of arbor, height of shrub and trend of aspect were the main factors in summer. The results of t-test and U-test between spring and summer showed that: the number of the conifer, diameter of the trees, height of the shrub, cover of the shrub, cover of moss and cover of the grass, as well as the trend of aspect were significantly different.
