岷山山系南端大熊猫栖息地分布分析

Analysis of Giant Panda Habitat at the Southern of Minshan Mountains

基于大熊猫Ailuropoda melanoleuca野外分布数据及环境变量,利用MaxEnt模型对岷山山系南端的大熊猫适宜栖息地分布进行了预测及分析。结果显示:研究区域内有大熊猫适宜栖息地330.9 km^2,占研究区域内保护区总面积的23.2%;并且龙溪虹口-白水河-九顶山一线的大熊猫的栖息地存在一定的破碎化现象。建议继续加强对大熊猫栖息地的保护,减少人为干扰,促进大熊猫栖息地的恢复,增进各相邻保护区间的沟通交流、数据分享,更准确掌握、了解该区域大熊猫的动态。

Based on the field distribution data and environmental variables,the MaxEnt model was used to predict and analyze the suitable habitat distribution of giant pandas(Ailuropoda melanoleuca)at the southern of Minshan Mountains.The results showed that there were 330.9 km^2 of suitable habitat for giant pandas,accounting for 23.2% of the reserves in the studied area,and the habitat of giant pandas in Longxi Hongkou-Baishuihe-Jiudingshan was fragmented.To understand the population dynamics of giant pandas in this area more accurately,it is recommended to continue to strengthen the protection of giant panda habitat,reduce human disturbance,and promote the recovery of habitat,and to enhance the communication and data sharing of the neighbor reserves.
