岷山北部大熊猫栖息地破碎化研究

以全国第三次大熊猫调查数据和2005~2007年的野外调查数据为基础，利用地理信息系统、遥感软件和景观格局分析软件，对岷山北部区域大熊猫生境的分布、适宜性和空间格局进行了分析，结果表明：（1）在岷山北部791445.51 hm2的研究区域内，大熊猫潜在生境的面积为91129.14 hm2，由于人为活动的影响，实际生境面积仅为89113.5 hm2，占研究区域总面积的11.26%；（2）在大熊猫实际生境中，适宜栖息地面积占30.4%，最适合大熊猫取食的竹类盖度（大于50%）的竹林面积仅占实际生境的20.2%

A study on giant panda habitat fragmentation in north minshan mountains

Based on the data of the Third National Survey and 2005~2007 field survey, using the GIS and RS softwares,the distribution, suitability and spatial pattern of giant panda habitat in North Minshan Mountains were studied. It was found that: (1) The potential habitat of giant panda in this region covered 91129.14 hm~2. However, affected by the human activities the factual habitat was only 89113.5 hm~2, accounting for 11.26% of the total survey area. (2) Only 30.4% of the factual habitat was most suitable for giant panda, and the area of pandas' preferred bamboos (coverage above 50%) was about 20.2%. (3) The landscape indexes showed that the giant panda habitat in this area was in a considerable fragmented situation, being separated into a great many patches, the average area of which was quite small. As for this condition, protection and management measures for the giant panda and its habitat were proposed.
