洁白的羽毛,艳红的头冠和黑色的长嘴,加上细长的双脚,朱鹮历来被日本皇室视为圣鸟.
20世纪前朱鹮在中国东部、日本、俄罗斯、朝鲜等地曾有较广泛地分布,由于环境恶化等因素导致种群数量急剧下降,至20世纪70年代野外已认为无踪影.
1981年5月,中国鸟类学家经多年考察,在陕西省洋县重新发现朱鹮种群,一共只有7只,也是世界上仅存的种群.
此后对朱鹮的保护和科学研究做了大量工作,并于1989年在世界首次人工孵化成功.

火干扰对小兴安岭白桦沼泽和落叶松鄄苔草沼泽凋落物和土壤碳储量的影响周文昌,牟长城*,刘摇夏,顾摇韩(东北林业大学生态研究中心,哈尔滨摇150040)摘要:火干扰在湿地生态系统中起着重要的作用,尽管湿地占全球陆地生态系统很小一部分,却是陆地生态系统一个重要的碳汇.
然而关于火干扰对我国小兴安岭森林沼泽生态系统土壤碳库影响的研究鲜有报道.
因此选取两种森林沼泽典型地段进行土壤取样,研究火干扰对小兴安岭白桦(Betulaplatyphylla)沼泽和落叶松(Larixgmelinii)鄄苔草(Carexschmidtii)沼泽地表凋落物和土壤碳储量(0—50cm)的影响.
研究结果表明:淤重度火烧使得白桦沼泽地表凋落物量和碳储量降低了36.

1摇火干扰对森林沼泽地表凋落物量和碳储量的影响火干扰对小兴安岭两种森林沼泽地表凋落物量和碳储量有影响,重度火烧减少了白桦沼泽地表凋落物量和碳储量,而轻度火烧对其无显著影响.
火干扰减少了落叶松鄄苔草沼泽地表凋落物量和碳储量,两种森林沼泽就地表凋落物量和碳储量减少程度来说,重度火烧减少程度大于轻度火烧(图1,图3).
而针对不同森林沼泽,火干扰对两种森林沼泽地表凋落物量和碳储量的影响程度不一致,重度火烧白桦沼泽地表凋落物量和碳储量减少约1/3,而2种火烧强度对落叶松鄄苔草沼泽地表凋落物量和碳储量减少约1/2(图1,图3).
分析其原因,在火烧期间,火烧直接燃烧掉了湿地地表大量未分解掉的地表凋落物,使得地表凋落物量及碳储量减少;同时火烧也烧掉了全部草本、灌木及部分乔木,使得凋落物的来源减少,从而使得地表凋落物量及碳储量减少;此外,在火烧结束后,增加了地表辐射,温度上升,进而加速了地表凋落物的分解[28鄄29,33鄄34],也可能导致地表凋落物量及碳储量的减少.
本研究结论与现有火干扰减少了湿地地表凋落物量的研究结论基本一致[35],与其他学者研究北方泥炭地火烧直接烧毁地表有机质碳储量损失一致[12,24].
由于落叶松鄄苔草沼泽一般位于森林沼泽生态交错带上位,在沿着沼泽至毛赤杨、白桦、落叶松森林沼泽群落方向上,环境梯度相对高于白桦沼泽[36],可能地表水位低于白桦沼泽,地表凋落物湿度较小,而适合可燃物燃烧的量较多,可能是导致落叶松鄄苔草沼泽地表凋落物量和碳储量减少程度大于白桦沼泽的原因.
因此,今后有必要从微地形(水文)、可燃物类型等进一步去研究火烧后地表有机质的变化.

2摇火干扰对森林沼泽土壤碳储量的影响小兴安岭白桦沼泽和落叶松鄄苔草沼泽两者对照样地与火烧样地的土壤碳储量(0—50cm)范围分布在(18.
50依8.
16)—(32.
50依7.
22)kgC/m2之间.
本文研究结果大于蔡体久等[37]研究小兴安岭泥炭藓湿地土层0—60cm土壤有机碳储量(16.
61kgC/m2),该学者认为湿地土壤有机碳储量比其他学者研究的湿地土壤有机碳储量小是因土壤容重(0.
027—0.
097g/cm3)较小所致.
同理,本文研究的湿地土壤容重(0郾25—1.
45g/cm3)与其比较较大,导致土壤有机碳储量较大.
比张文菊等[38]研究相同纬度三江平原典型湿地(常年积水的腐殖质沼泽)土层0—60cm土壤有机碳储量(36.
6kgC/m2)小,可能是由于本文研究的森林沼泽为季节性积水,通气状况在非积水时期有所改善,植物残体分解程度较高,导致土壤有机碳储量较小;也有学者认为湿地土壤有机碳含量较其它生态系统(森林或草原)高,然而可能因湿地更低的土壤容重(或泥炭密度),也可能会引起湿地更低的土壤碳库[39].
因此,要搞清楚不同湿地类型土壤有机碳储量的精确数据,必须对不同湿地类型、分布及生境因子开展系统的调查和研究.
从不同火烧强度、不同林型下分析两种森林沼泽土壤有机碳储量的差异性,唯有重度火干扰落叶松鄄苔草沼泽表层(0—10cm)的土壤碳储量有显著的下降(4.
61kgC/m2).
这与Turetsky等[24]研究北方泥炭沼泽火烧3个月后表层(0—30cm)土壤有机质碳储量下降((2.
2依0.
5)kgC/m2)一致,但不同之处是该研究者的结论在火烧地与未火烧地间土壤表层有机质碳储量之间差异不显著.
本研究也与Meigs[40]研究在不同火烧强度下森林生态系统土壤碳储量(土层0—20cm或甚至达到100cm)之间影响不显著相吻合.
其可能原因:火烧后,草本、灌木生物量以及地下细根生产力的增加[40鄄42],使得干扰后土壤碳得以恢复[43];另一个是,本文研究地段火烧时间(2009年4月下旬)为小兴安岭森林沼泽土壤层还未冻融,火烧期间可能未烧毁下层土壤有机碳,仅仅是烧毁了两种森林沼泽地表长期积累较厚的凋落物层(图1),短期内,未对其土壤碳储量造成显著性影响.
火干扰对土壤有机碳储量的影响是一个相当复杂的过程,要搞清楚火干扰对生态系统土壤碳储量的影响,尚须进行长期定位研究和监测.
例如,有学者认为不同生态系统之间土壤碳储量的差异性的关键因子可能与以前生态系统受到家畜和野生动物干扰密切相关[39].
因此,火烧前生态系统干扰的历史原因与火烧后细根变化量可能加大了土壤碳储量的空间异质性.
4摇结论火干扰(不同火干扰强度)一般是减少小兴安岭白桦沼泽和落叶松鄄苔草沼泽两者地表凋落物储量和碳储量.
除了轻度火烧白桦沼泽减少不明显外,其它火烧强度是显著地减少了地表凋落物量和碳储量,且有重度火烧减少的程度较大的趋势.
火干扰对小兴安岭白桦沼泽和落叶松鄄苔草沼泽两种森林沼泽土壤碳储量(0—50cm)影响不显著,但是重度火烧对落叶松鄄苔草沼泽表层(0—10cm)土壤碳储量有显著地减少.
本结论将为我国东北开展湿地土壤碳管理和计划火烧提供理论的依据.
