血雉繁殖期活动区与栖息地特征

采用无线电追踪技术并结合野外观察，对血雉繁殖期活动区与栖息地特征进行了研究。孵卵期(5月)雄鸟的活动区面积为31．90hm^2，雌鸟为8．67hm^2。育雏期一个家族的活动区面积为15．45hm^2(6月)和17．33hm^2(7月)。繁殖季节相邻两个繁殖对的活动区有重叠。血雉繁殖季节喜欢在北坡和东坡活动，这种选择与食物的分布有关。倒木在繁殖期栖息地选择中占有一定地位。用多元总体假设检验、单变量F检验及主成分分析法对实验样方与对照样方间进行了比较分析。结果表明，繁殖期喜选择山脊附近下层空间较为斤阔的灌木林或林间空地。

Home Range and Habitat Characteristics of Blood Pheasant in Summmer

The home range and habitat characteristics of blood pheasant (Ithaginis cruentus)in breeding season was studied in Wuyipeng area of Wolong Nature Reserve in Sichuan Province by radio-telemetry and field observations.In incubating period(May),the home range size of male was 31.90 hm~2 and that of female 8.67 hm~2.When female was incubating,the home rage of male was 28.11 hm~2.The sizes of brood's home range were 15.45 hm~2(June)and 17.33hm~2(July).The home ranges of the neighbour pairs were overlapped.The activity of blood pheasant was related to the aspect and the ridge of a hill.In summer the birds preferred to living in the northern slope and eastern slope,which were related to the distribution of foods.Hotelling's T~2 test,MNOVA and Principal content analysis were used to compare the animal plots and the control plots in summer.The results showed that the birds preferred to living in shrubs or open ground in the forest where the cover was lower in breeding season.
