摘 要:以近年林地调查数据为基础对四川境内岷山山系大熊猫栖息地和潜在栖息地范围的景观格局特征进行研究,结果显示:(1)作为大熊猫活动痕迹点分布最多的景观类型,针叶林和阔叶林表现出破碎度最低、斑块形状最复杂、斑块聚集度和连通性高、稳定性强的特征,表明目前研究区大熊猫栖息地质量良好、自然度高;(2)人工经济林、耕地和建设用地分布面积占5%,这些景观类型的人类活动强度大,零散分布于整个研究区,给大熊猫栖息地带来持续干扰;(3)随着平均海拔降低、干扰强度升高,研究区景观格局由北向南表现出破碎度、混合度、多样性和均匀度升高,景观质量和功能下降的趋势。本文提出落实退耕还林政策、改造人工经济林、控制大熊猫栖息地内建设用地规模和转变原住民生产生活方式等保护管理措施,以逐步恢复提升大熊猫栖息地质量。Based on forest land survey data in recent years,the landscape pattern characteristics of the giant panda habitat and potential habitat range were studied,in the Minshan Mountains of Sichuan province.The results showed that:(1)As the landscape type with the largest distribution of giant panda activity trace points,coniferous forest and broad-leaved forest showed the characteristics of the lowest fragmentation,the most complex patch shape,highest patch aggregation and connectivity,and strong stability,indicating that the quality of giant panda habitat of the study area was good and with high naturalness.(2)The distribution area of artificial economic forest,cultivated land and construction land accounted for 5%.These landscape types had high intensity of human activities and were scattered throughout the whole research area,bringing continuous disturbance to the giant panda habitat.(3)With the decrease of the average altitude and the increase of the disturbance intensity,the landscape pattern in the study area showed a trend of increasing fragmentation,mixing degree,diversity and evenness,and decreasing landscape quality and function from north to south.Some protection and management measures were put forward,such as implementing the policy of returning farmland to forest,transforming artificial forest,controlling the scale of construction land in the giant panda habitat and changing the production and life style of the indigenous people,so as to gradually recover and improve the quality of the giant panda habitat,.
