别说大熊猫不濒危

2015年中国国家林业局公布数据显示中国大熊猫数量已经增加1864只,根据这一结果世界自然保护联盟将大熊猫由濒危物种降至易危物种。作者们指出这一结果未免过于乐观。（1）大熊猫的食物主要为竹子,CO₂浓度升高将影响竹子的生长发育,缩短竹子的生命周期,导致竹子提前开花,提前死亡;温度升高延长了竹粘虫等灾虫的生活周期,增加粘虫等害虫数量,影响竹子的产量和品质,从而威胁熊猫生存。（2）470 km长的龙门山地震带穿越四川亚种熊猫部分栖息地。遥感数据显示2008年汶川地震导致卧龙保护区进一步破碎化。（3）随着私家车的普及高速公路快速发展,生态旅游活动加剧,而人类活动影响动物荷尔蒙分泌、新陈代谢及生殖,增加疾病传播风险。（4）大熊猫栖息地环境污染日趋严重,直接威胁着大熊猫生存和健康。因此,大熊猫保护是一项长期的、艰巨的任务,世界自然保护联盟降级大熊猫保护等级为之过早,大熊猫依然是一个濒危物种,全球应该继续关注中国大熊猫保护。

大熊猫的摇篮：蜂桶寨国家级自然保护区（续）

1983年，邛崃山系冷箭竹几乎全部开花死亡。冷箭竹约60年一轮周而复始的开花、结籽、枯死，这种规律在自然界已经存在几百万年，这对大熊猫生存有利也有弊。弊是会造成一部分年轻、体弱、有病、活动范围不广的大熊猫死亡，使大熊猫种群数量下降。利是食物环境变化，使一部分大熊猫异地寻食，改变了每天只活动500米范围的习性，促使大熊猫远亲交配，使大熊猫更能适应自然环境，避免近亲交配、素质下降和孤身只影的生活。目前大熊猫的栖息地和1985年相比，有什么变化?我问王鸿加。他说：最近的问题是竹子又在大面积开花。要说这也是自然规律，…
