摘 要：
采笋是大熊猫栖息地内一种持续的人类干扰活动。为了评估采笋对大熊猫主食竹竹笋生长发育的影响,2009年7—11月,在四川省洪雅县瓦屋山镇设置实验样方,对比研究了早期采笋、中期采笋、晚期采笋、一直采笋和不采笋5种采笋方式对大熊猫主食竹八月竹竹笋生长和发育的影响。结果表明:1)早期采笋、中期采笋和一直采笋样方的发笋量显著高于不采笋样方(P<0.05),其发笋量分别是不采笋的1.53倍,1.57倍和1.62倍;晚期采笋样方发笋量与不采笋样方差异不显著(P>0.05)。2)早期采笋使八月竹在发笋早期和发笋中期的发笋量增加,中期采笋仅使八月竹在发笋中期的发笋量增加,而一直采笋使八月竹在整个发笋期的各个阶段的发笋量均显著增加(P<0.05)。3)一直采笋样方的幼竹数量、株高均显著低于其他采笋样方,其基径只显著低于不采笋样方(P<0.05);早期、中期、晚期采笋和不采笋样方相互间仅幼竹株高差异显著(P<0.05)。4)早期、中期和晚期采笋与不采笋样方的发笋总量、退笋总量和采笋总量相互之间均呈显著正相关(P<0.05)。建议仅在八月竹发笋中期采笋,同时政府应加大对大熊猫栖息地周边社区经济发展的引导和扶持。

摘 要：
Bamboo shoot-collecting is a lasting human disturbance activity in giant panda's habitat.To estimate how the behavior of bamboo shoot-collecting affects the shoot growth of giant panda's diet bamboo,a field experiment was conducted to study the shoot growth of Chimonobambusa szechuanensis affected by the shoot-collecting at different time from July to November,2009 at Wawushan Town,Hongya County of Sichuan Province.Five different ways of shoot-collecting were set up during shooting period:A)early period(days 1-15)shoot-collecting,B)mid-period(days 16-30)shoot-collecting,C)late period(days 31-45)shoot-collecting,D)continual(days 1-45)shoot-collecting,and E)no shoot-collecting.The total amount of bamboo shoots in treatments A,B,and D was 1.53,1.57,and 1.62 times of that in treatment E,respectively,but no significant difference was observed in the bamboo shoot amount between treatments C and E.Treatment A increased the amount of budding shoot in the early and mid-period.Treatment B only increased the amount of budding shoot in the mid-period,while treatment D increased this amount all the periods(P<0.05).There was significant difference in the stem height of young bamboo between treatments A,B,C,and E respectively(P<0.05).The amount and stem height of young bamboo in treatment D were significantly lower than those in other treatments,and the basal diameter of young bamboo in treatment D was only lower than that in treatment E(P<0.05).There were positive correlations between the amounts of shooting,withering,and collecting in all treatments except D(P<0.05).It was suggested that the mid-period of shooting was the optimal time for bamboo shoot-collecting,and the local government should pay more efforts to guide and support the economic development of the surrounding communities of giant panda's habitats.
