1) δ~(13)C sequence
δ13C序列
1.
Being measured and compared to the δ~(13)C sequence of cellulose the δ~(13)C sequence of humic acid is very similar to the former’s, and changes more distinctly than the latter.
泥炭纤维素δ13C变化是反映气候干湿变化的一个重要气候代用指标,但泥炭纤维素的提取工序复杂,因泥炭胡敏酸提取方便,为了探索泥炭胡敏酸δ13C对古气候的指示意义,对金川泥炭胡敏酸δ13C与泥炭纤维素δ13C进行了对比研究,发现胡敏酸δ13C序列变化与纤维素δ13C序列变化非常相似,且胡敏酸δ13 C序列的变化更为明显,胡敏酸δ13C值对古气候的干湿变化也具有一定的指示作用,但应用时要慎重。

Four long-term agricultural field experiments combined with an laboratory incubation experiment were conducted to evaluate the effect of organic,inorganic and organic+inorganic fertilizer application on δ13C value of soil organic matter(SOM)and humic acid(HA)in black soil,brown soil,meadow soil and paddy soil.
以黑土、棕壤、草甸土和水稻土为供试土壤,通过田间定位并结合室内培养试验,初步研究了不同施肥(包括施用化肥、有机肥以及有机肥配施化肥)条件下全土有机质和胡敏酸的δ13C值。

The foliar δ13C values were used to denote the long-term water use efficiency(WUE)of plants whereas long-term nitrogen use efficiency(NUE)was estimated by the ratio of C to N.
对长汀水土流失区不同生态恢复程度生境马尾松(Pinus massoniana)与木荷(Schima superba)的叶片稳定碳同位素组成(δ13C)、比叶面积(specific leaf area,SLA)、叶N含量及C/N进行了分析,并以叶片δ13C值和C/N分别指示植物的水分利用效率(water use efficiency,WUE)和氮素利用效率(nitrogen use efficiency,NUE)。
