以14C测年为基础,构建了天湖山泥炭剖面的年代序列,通过对研究区泥炭腐殖化度与有机质的分析研究,发现两者呈现出很好的相关性,共同记录了研究区约9．5kaBP以来的气候变化,可划分出3个主要阶段：1）早期（9．5 ka BP-6．3 ka BP）泥炭腐殖化度最低,指示气候湿热,其中7．9ka BP-6．3kaBP为整个剖面腐殖化度最低值阶段,可能为研究区全新世气候最适宜期（全新世大暖期）阶段;2）中期（6．3 ka BP～2．8 ka BP）泥炭腐殖化度较低,指示气候温凉湿润;3）晚期（2．8 ka BP以来）,泥炭腐殖化度偏高,波动较大,指示气候温凉偏于．利用redfit红色噪声谱分析发现,有机质含量变化时间序列中存在948a、268a、342a的准周期,反映了中低纬度亚热带季风区气候变化对太阳活动的响应． 相似文献

基于“综合-比例法”（Composite Plus Scale,CPS）,利用近年来已发表的数据集成重建我国华南北热带地区11.5―2.5 ka B.P.温度变化序列。结果表明,该地区冷暖变化可以分为三大阶段：11 500―9 500 a B.P.为全新世早期阶段;9 500―4 000 a B.P.为全新世大暖期阶段;4 000―2 500 a B.P.开始出现降温过程。功率谱和小波分析表明：华南北热带气候变化具有多时段、多尺度冷暖周期变化特征,在千年尺度上,1.3 ka和3.3~3.9 ka是其冷暖变化的主要周期。序列中可以识别出一系列气候波动事件,如8.2 ka、7.9 ka、7.1 ka、4.1 ka气候事件。交叉小波谱分析表明：ENSO对华南北热带地区温度变化有着显著影响,特别是7 ka B.P.以来其影响进一步加强。通过与其他序列的对比发现：华南北热带地区的气候变化是对全球变化的响应,但也同样存在区域差异。 相似文献

珠江三角洲中部番禺东涌剖面密取样、高分辨率的磁化率、δ13C、C/N3条曲线相互基本谋合,为判断MIS2以来的气候波动提供了新依据,从中得出了一些新认识：末次冰盛期很不明显,降温不超3℃;有新仙女木冷回返事件的反映;冷回返事件后直至2 500aBP,持续波动升温,难以识别8 500～3 000 a BP的大暖期;晚全新世降温始于2 500aBp,而不是3 000 aBP;最暖期不是在中全新世,而是在晚全新世. 相似文献

由南疆罗布泊地区台特玛湖沉积物多种地质记录的综合分析表明,近25．0kaBP以来此地区气候与环境演化的过程和特征与新疆其它地区基本一致。多手段的综合研究,揭示了近25．0kaBP以来台特玛湖气候与环境的变化经历了7次相对暖干、5次相对冷湿和1次相对暖湿变化,而且全新世期间历次的气候变化与具有高分辨率的敦德冰芯记录以及北半球气候变化的过程上基本一致,所记录的气候与环境演化过程呈现出明显的西风型环境演变特征。唯一在7．0～6．0kaBP期间出现的相对暖湿的环境特征应该是真正意义上的全新世大暖期最盛期的体现,可能与此时增强的西南夏季风势力影响到本地区有关。 相似文献

基于石笋记录的云贵高原古气候变化研究进展 总被引：1，自引：0，他引：1
重建古气候、古环境已成为当今全球变化研究的热点.石笋作为岩溶洞穴次生化学沉积物的典型代表,是古气候研究的重要载体.基于近年来已报道的贵州荔波、茂兰、都匀凯口及云南寻甸、宣威、宁蒗等地11个洞穴30余根石笋的氧同位素数据的综合分析,认识云贵高原163 kaBP以来的古气候变化情况.结果表明,163kaBP以来,青藏高原隆升对全球气候格局的改变及季风系统的形成起到重大影响,在此大背景下,云贵高原气候演变体现了全球一致性,也呈现出其自身规律：（1）倒数第2次冰期的冰盛期（163.3～ 129.28 kaBP）,气候严寒干冷,期间伴随温凉向冷干的转变;（2）末次间冰期（129.28～78.92 kaBP）,气候温暖湿润,但期间冷暖波动变化幅度很大;（3）末次冰期（78.92～11.2 kaBP）,气候极不稳定,冷暖波动很大,总体呈现降雨由多变少,气温由高变低的变化趋势;（4）全新世（11.2 kaBP至今）,气候温暖,雨量充沛,气候呈现变暖—高温—稍变冷—恢复的变化趋势.云贵高原作为一个特殊区域,即东亚季风与印度季风的过渡带,对研究中国甚至于全球季风系统的演变发展有着重要意义.通过多指标多手段,提高研究区研究精度,拟建古气候变化曲线,应对全球变暖的区域性实证研究及未来气候模拟预测将是今后努力的方向. 相似文献

古湖岸堤是湖泊湖面变化的地貌学证据,通过古湖岸堤沉积年代学研究可重建地质时期湖泊演化历史。青藏高原内陆湖泊众多,保存了大量的第四纪时期古湖岸堤,是研究过去湖泊演化和气候变化信息的重要载体。对青藏高原班戈错盐湖北岸和东岸的低位连续古湖岸堤开展了地貌调查和光释光年代学研究。结果表明班戈错自末次冰消期(13. 5±1. 2 ka BP)以来,湖面整体呈波动下降过程,期间出现了4期湖面稳定阶段,分别在末次冰消期(13. 5±1. 2～11. 2±1. 0 ka BP)、全新世早中期(10. 1±0. 8～6. 5±0. 5 ka BP)、全新世后期(4. 2±0. 4～3. 1±0. 2 ka BP)以及全新世晚期(1. 7±0. 1～1. 2±0. 1 ka BP)。全新世晚期约1. 7 ka BP以后湖面迅速退缩,湖泊蒸发浓缩进入盐湖阶段。在末次冰消期班戈错高湖面形成主要与北半球太阳辐射强度增加引起气温升高,导致区域冰雪融水量增加相关,而在全新世湖面变化主要受印度季风强度变化控制。 相似文献

通过对西天山温泉湿地钻孔沉积物Rb/Sr、Sr/Ca、Ti/Sr、Mg/Ca、Zr/Sr 5种特征元素比值综合分析与对比研究,识别温泉湿地全新世气候变化驱动模式。结果表明：（1）温泉湿地沉积物提供了新疆全新世气候变化的可靠记录,其全新世气候经历了暖干（10300—7700 cal a BP）-暖干向温湿过渡期（7700—7000 cal a BP）-温湿（7000—4200 cal a BP）-温干（4200—2900 cal a BP）-冷湿（2900—81 cal a BP）5个阶段变化过程。（2）与邻近区域其他替代性指标所指示的气候变化相吻合,验证了新疆地区全新世早期暖干、中晚期冷湿的气候变化模式,表明新疆地区全新世气候类似于西风模式。（3）温泉湿地沉积物化学元素比值在7700—7000 cal a BP期间指示的降温过程是8200 cal a BP全球变冷事件的响应;4200—2900 cal a BP期间指示的升温过程或许与3000—2900 cal a BP敦德冰芯反映的全新世次高温事件相关。同时,与周边区域其他替代性指标对比发现,新疆地区逐渐湿润的变化趋势可能是全新世温度... 相似文献

对汉江上游谷地弥陀寺黄土剖面的地层序列和常量元素进行了研究,用光释光测年法(OSL)对地层进行了断代。结果显示:剖面中Na2O、Mg O、Ca O表现淋失,Fe2O3、K2O和Al2O3则相对富集,其中在古土壤中这些元素表现淋失或富集程度更为强烈;剖面具有斜长石风化为主的初级化学风化程度,以Ca、Na流失严重为特征;从马兰黄土L1→古土壤S0→全新世黄土L0,风化由弱变强再变弱。这些信息揭示了汉江上游地区晚更新世以来的环境尤其是气候的变化规律:18 000~11 500 a BP气候以干冷为主,进入全新世后逐渐转暖,8 500~3 100 a BP为全新世大暖期,气候温湿,3 100 a BP后气候又转凉,呈现出由"冷干→转暖→暖湿→干凉"的演变过程,同时弥陀寺黄土对6 000~5 000 a BP期间发生的气候波动冷事件也有记录响应。 相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing. 相似文献
