【摘要】 为了评估采笋管理政策对马边大风顶自然保护区大熊猫生境恢复的作用,2018年9月对保护区内采笋管理区域和保护区外围保护带的未管理区域进行了野外调查,对比分析采笋管理区域与未管理区域大熊猫主食竹——八月竹(Chimonobambusa szechuanensis)的生长状况以及森林植被特征。结果显示:1)采笋管理区域的竹笋株高与数量明显大于未管理区域的相关指标(p <0. 05),竹笋基径,成竹株高无明显差异。2)采笋管理区域乔木胸径,乔木树高,灌木层盖度大于未管理区域,且差异显著(p <0. 05)。可见,采笋管理政策对马边大风顶自然保护区大熊猫主食竹的恢复产生正面作用,而连续采笋不仅影响了大熊猫主食竹的生长,也在改变大熊猫生境的森林植被特征。为了更好的保护当地大熊猫的生存,保护区实行科学的采笋管理政策是有效的,建议在其他保护区推广。更多还原

【Abstract】 In order to estimate the effects of the controlling policy of collecting bamboo shoots on the panda habitat recovery in Mabian Dafengding Nature Reserve,a field survey was carried out to compare the growth and vegetation community structure of Chimonobambusa szechuanensis in the controlling area of collecting bamboo shoots with those in the outer unmanaged protection area in September 2018. Chimonobambusa szechuanensis was the main food of giant pandas. The results showed that 1) the height and number of bamboo shoots,the basal diameter and quantity of bamboo in the controlling collecting bamboo shoots areas were significantly higher than those in the unmanaged area(p < 0. 05),the base diameter of bamboo shoots,the height of bamboo showed no significant difference. 2) the DBH and height of trees,the cover degree of shrub layer in the controlling collecting bamboo shoots areas were greater than those in the unmanaged areas(p < 0. 05). Thus it could be seen that the controlling collecting bamboo shoots policy had a positive effect on the recovery of the main food bamboo of giant pandas in the Mabian Dafengding nature reserve. Continuous bamboo shoots collecting not only affected the growth of bamboo,but also changed the vegetation structure characteristics of the giant panda habitat. For better to protect the giant pandas in Mabian Dafengding Nature Reserve,the conservation areas were effective to implement scientific management policy on controlling collecting bamboo shoots,which should be recommended in other conservation areas.更多还原
