| 1 | 黄土高原中部450ka以来植被演化的有机碳同位素与分子化石记录显示文摘黄土高原地质历史时期不同时间尺度上的植被演化规律与气候环境影响因素,以及植被替代性指标的解译等问题还值得进一步研究.本工作拟通过对灵台黄土剖面450ka以来黄土-古土壤样品总有机碳同位素(δ^(13)CTOC)和正构烷烃含量组合参数如C31/C27进行综合对比研究,从而为明晰这些问题提供一些新的讨论和证据.结果表明,450ka以来黄土高原中部C_3、C_4植物混生,以C_3植物为主;按生活型则草本、木本混生,以草本植物为主.在黄土高原气候较温暖湿润的MIS9(S3时期),MIS5(S1时期)阶段,可能出现过C_3木本植物的短暂增多,但总体上不存在大面积的森林.在阶段性变化上,黄土高原130ka以来草本植物总体增多,可能与区域性气候干旱化有关.在轨道尺度上,全新世较末次冰期,MIS11(S4时期)较MIS12(L5时期)C_3草本植物减少;在其他几个冰期旋回,间冰期较相应冰期C_3草本植物增多.植被替代性指标与建群种蒿属孢粉量的变化吻合较好,其变化可能与冰期旋回上水热配置有关.MIS1(S0时期)与MIS11(S4时期)气候相似,但全新世时期松属乔木的大量增多,暗示了人类活动和生态因子火活动的影响. | 周斌 古再丽努尔·外力 France PETERSE Michael I BIRD | 2016 | 中国科学:地球科学2016，46，4： | 11 |
| 2 | Organic carbon isotope and molecular fossil records of vegetation evolution in central Loess Plateau since 450 kyr显示文摘Significant uncertainties remain regarding the temporal evolution of natural vegetation during the Quaternary, and drivers of past vegetation change, on the Chinese Loess Plateau(CLP). This study presents analyses of total organic carbon isotopic composition(TOC) and n-alkane ratios(C31/C27) from the Lingtai loess-palaeosol sequence on the central CLP over the last 450 kyr. The results demonstrate that the vegetation in this region comprised a mix of C_3 and C_4 plants of herb and woody growth-form. C_3 plants dominated for most of the last 450 kyr, but this did not lead to extensive forest. C_3 woody plants were more abundant in MIS9(S3 period) and MIS5(S1 period) during warm and humid climate conditions. Herbs increased in the region since 130 kyr, possibly as a result of increased aridity. On the orbital timescales, there was a reduction of C_3 herbal plants in MIS11(S4) than in MIS12(L5), and in Holocene than in the last glacial period. Our isotope and n-alkane proxy records are in agreement with Artemisia pollen changes in the region, which is/was the dominant species in this area and varying due to different heat and water conditions between glacial and interglacial periods. Though the climate in MIS1(S0) was similar to that in MIS11(S4), a significant increase in woody plants during the Holocene suggests the impact of human activities and ecological effects of changes in fire activity. | ZHOU Bin WALI Guzalnur Francien PETERSE Michael I BIRD | 2016 | Science China Earth Sciences2016，59，6： | 7 |
