| 摘 要： | 2005年3-11月采用样线法和样方法对大相岭北坡大熊猫栖息地进行了调查,通过利用样方法发现的大熊猫痕迹频次对栖息地的适宜性进行景观连接度（适宜性）赋值,对大相岭北坡大熊猫栖息地的质量进行了分析评价。研究区面积约为2266.79km^2,其中竹林分布面积约为842.3km^2。仅有约56.8km^2占6.8%的竹林面积是适宜大熊猫生存的地区,次适宜地区面积为96.3km^2,约占11.4%,较差适宜地区面积为177.4km^2,约占21.1%,3个等级加到一起共为330.5km^2,占竹林面积的39.3%,主要分布在2200-2800m的平缓山坡,有60%以上为不适宜地区。人为活动对大熊猫栖息地的影响主要是不仅减少了大熊猫的生境面积,也降低了大熊猫亚种群之间的景观连接度,对大熊猫种群之间的基因交流产生阻碍。作者通过实际调查提出了管理措施。 |
| 关 键 词： | 大熊猫 生境破碎化 景观连接度 大相岭山系 |

| Abstract: | We investigated giant panda(Ailuropoda melanoleuca)habitats on the northern slopes of the Daxiangling Mountains during March-November 2005.Habitat suitability was assessed using a Geographic Information System(GIS).The study area covers 2 267 km2,of which bamboos cover about 842.3 km2.Suitable,less suitable and marginally suitable habitats respectively covered 56.8 km2,96.3 km2 and 177.4 km2,and constituted 39.3% of the bamboos area.Suitable habitats were mainly distributed on flat slopes at elevations of 2 200-2 800 m.More than 60% of the study area was unsuitable for pandas.Human activities greatly influenced habitats inhabited by giant pandas,including reduction of suitable habitats and decreasing landscape connectivity among subpopulations.We propose management measures for giant panda habitat. |
