龙草坪林业局森工经营与大熊猫活动分析

陕西省龙草坪林业局主要森工经营活动对秦岭大熊猫生境破碎化产生了影响.特别是20世纪80年代后期,采伐、更新均受到市场经济的影响趋于速成,结果造成大熊猫栖息地破碎化,以至第二次全国大熊猫普查时未发现分布.全面停止采伐活动后,在毗邻佛坪保护区地段又发现了大熊猫分布.本文该局对经营活动对大熊猫生境破碎化影响进行了初步分析,为研究大熊猫栖息地恢复和提高天然林保护的效益等提供了科学依据.

Influence of the Forest Management on the Activity of the Giant Panda in Longcaoping Forest Area

The main activities of forest management in Longcaoping have disturbed the habitat of giant panda occurring in Qinling Mountains. In the late 1980s especially, the activities of forest management such as cutting and regeneration increased with great frequency due to the drive of marked economy resulting the fragmentation of the habitat of giant panda, and leading to the-fact that no giant panda was found during the second nationally general investigation. Giant pandas have been found however after the overall suspending of cutting in the area adjacent to the national nature reserve of Longcaoping. A preliminary analysis is conducted on the fragmentation of the habitat of giant panda cause by forest management to provide scientific basis for the regeneration of the habitat of gaint panda and the promotion of the benefits of natural forest protection.
