在2006年~ 2009年的监测数据的基础上,2012年采用样线调查、样方调查的方法,调查了6条样线、26个样方,评估地震前后四川白河自然保护区大熊猫主食竹及栖息地的变化情况.结果表明:“5· 12”汶川特大地震对白河自然保护区大熊猫主食竹及生境的影响很小,仅对海拔1 500 m~2000m的箭竹生长产生了负面影响.地震后人为干扰的强度增加,主要集中在海拔2 500 m~3 000 m的范围.箭竹更新一般,更新最差的主要集中在海拔1 500m~2000m范围.2012年的调查结果显示,箭竹生长状况低于震前水平,人为干扰强度有所降低,但强于震前水平.
On the basis of collecting data monitored from 2006 to 2009, investigations were made of traits of staple bamboos and the habitat for giant pandas in the Baihe Nature Reserve in 2012. The results indicated that the earthquake had minor negative effects on bamboos and the habitat except the bamboo growing in altitudes of 1 500 m - 2 000 m. Human disturbance intensity increased especially in the areas with an elevation of 2 500 m - 3 000 m. Bamboos did not naturally regenerate well in the area of elevation with 1 500 m - 2 000 m. The bamboo growth became worse, and human disturbance intensity was stronger than before the earthquake.
