Reconstructing past changes of paleovegetation in South-West China（SE Tibet） is key to understanding the paleoclimatic dynamics of the Indian summer monsoon（ISM）.Over the past few decades,research in this field has mainly concentrated on the Holocene and deglacial period,which limits our understanding of the evolution of the ***,we provide a 68 kyr lacustrine paleoclimatic record collected from Tengchong Qinghai Lake in SE *** pollen and charcoal analysis,combined with specific pollen identification of Quercus using scanning electron microscope,were *** results reveal that the high percentage of Quercus pollen particularly in the last glacial period was actually derived from the species of sclerophyllous Quercus living in the high plateau,which are totally different from the species of Cyclobalanopsis that is distributed at low *** vegetation stages are recorded,which corresponds to the Quercus forest of Tibetan evergreen sclerophyllous（TES） during the glacial period,evergreen broadleaved forest in the Holocene and secondary forest（Alnus） at the last 4.0 *** micro-charcoal agrees with pollen PCA-1 proxy showing that relatively high precipitation occurred in the MIS3 and the mid-Holocene,while the lowest temperature/precipitation period was 28.4–18.0 cal kyr BP,which happens to correlate with the Last Glacial *** center Quercus（TES） belt at the LGM was about ～1000 m lower than in present SW China,indicating a temperature 5–6℃ lower than *** simultaneous coupling of our data with the sea surface temperature in the Indian Ocean illustrates that the variability of Indian summer monsoon should be crucial for the change of energy/moisture transmission in SW China,and that the Antarctic glacial-interglacial ice-sheet changes may play a key role in driving the circulation and water temperature of the Indian Ocean.

通过对大九湖6m长连续沉积岩芯剖面(DJH-1孔)7个样品的AMS14C年龄测定和151块孢粉样品的鉴定分析,揭示了神农架区域4万以年来植被和气候演变。末次冰期阶段大九湖附近发育森林草地或草地—草甸植被。MIS3晚期,～42-39calkaBP之间,气候相对干冷,发育森林草地;～39-31calkaBP之间,气候较为湿润,草甸扩张并伴随低海拔阔叶树种的发育。MIS2阶段,草甸组分中蒿属显著增加,高海拔可能分布有荒漠草地,气候极端干冷;该时期植被带垂直下降达到1000余m,按垂直温度递减率推算,冰盛期阶段该区域温度下降约7℃左右。从冰消期开始,森林植被开始扩张,北温带、暖温带和亚热带乔木组分依次增加。约在9.4-4calkaBP之间,演变为亚热带常绿阔叶落叶林,属全新世适宜期;从约4calkaBP以来,北温带阔叶和针叶树开始增加,气候趋于凉干。通过对比区域高分辨率的洞穴石笋及高纬冰芯氧同位素记录,表明神农架区域植被环境变化对气候变化敏感,并记录了H1,YD气候突变事件;进一步体现出该区域气候环境演变主要与北半球太阳辐射控制的东亚夏季风强度变化有关,且与北半球高纬气候变化一致。

对雷州半岛东南部的田洋玛珥湖TYC孔前40 m岩芯进行了研究,结果表明,磁化率与孢粉有很好的对应关系,因而磁化率值的高低变化能够作为该区气候环境变化的替代指标。沉积物磁化率与气候变化的关系为:磁化率的低值与气候暖湿对应;磁化率的高值则与气候寒冷或温凉相对应。中更新世以来,田洋玛珥湖气候环境演化经历了9个不同的阶段:346～301.4 kaBP,气候相对暖湿。301.4～248.8 kaBP,气候寒冷干燥。248.8～188.8 kaBP,气候相对暖湿。188.8～125.2 kaBP,气候寒冷干燥。125.2～69.3 kaBP,气候较为暖湿。69.3～40.43 kaBP,气候偏凉。40.43～25.5 kaBP,气候偏凉但较上阶段温度低,此时玛珥湖呈现出沼泽化过渡阶段。25.5～10.8 kaBP,气候寒冷干燥,玛珥湖干枯成为干玛珥湖。10.8 kaBP以来,由于后期人类活动对玛珥湖的改造,致使磁化率值不断升高。

对广州2种典型森林土壤碳库分配特征进行了研究，结果表明：①两种森林土壤有机碳（SOC）表层含量及其差异程度最高，随土壤深度增加，差异逐渐减小。马尾松林SOC密度范围为55．54～66．69t／hm2，常绿阔叶林SOC范围为84．91～151．16t／hm2。②两种森林土壤活性有机碳（AOCs）含量为马尾松林〈常绿阔叶林；各种AOC分配比例均随龄级增长而升高。③两种森林土壤的水溶性有机碳（WSC）、易氧化态碳（EOC）和微生物量碳（MBC）含量分别与SOC相关性达到极显著水平，轻组碳（LFC）与颗粒性碳（POC）含量分别与SOC相关性达到显著水平。④幼龄林与中龄林的土壤碳库大于相应的地上部植被碳库，而成龄林的土壤碳库小于植被碳库；土壤碳库占森林生态系统总碳库的比例随着生物量的增长呈下降趋势。

通过对长江下游安庆池州市地区钻孔岩芯开展古环境变化研究,基于岩芯5个沉积物样品的AMS14C测年结果建立沉积深度-年龄框架,根据孢粉分析结果探讨研究区域MIS3晚期以来古植被演变过程,并分析了全新世晚期人类活动对植被的干扰信号。研究结果表明:1)在MIS3阶段晚期(~30540~25330 cal a BP),研究区域植被类型表现为常绿落叶阔叶混交林,优势种类以壳斗科常绿类型青冈属和松属植物为主,落叶栎属和栗/锥属植物相对较少,反映了当时气候为温暖湿润;2)在MIS2阶段(25330~9640 cal a BP),研究区域植被以落叶阔叶林为主要特征,该阶段气候从末次盛冰期时期的寒冷干燥逐渐转变为温凉湿润;3)在早-中全新世阶段(9640~5180 cal a BP),森林植被开始繁盛,尤其是乔木类植物含量达到峰值,反映出当时气候温暖潮湿;4)在晚全新世阶段(5180 cal a BP以来),禾本科植物花粉(>40μm)剧增,可能与当时稻作农业规模增大有关;同时乔木类花粉锐减,反映了人类活动对自然植被干扰强度增加。

根据吊罗山自然保护区不同海拔6个植物群落的样方资料,分析了吊罗山植物群落结构特征和物种多样性,同时比较了吊罗山植物群落与邻近地区植物群落的组成特征。研究结果表明吊罗山低地雨林乔木层以蝴蝶树、青梅、高山榕、粘木、长脐红豆、海南柿、肉实树和海南木莲为主,灌木层以白颜树、白茶、柏拉木和九节为主;山地雨林以陆均松、鸡毛松、黄叶树、阿丁枫、扫把青冈和海南杨桐为优势种;山顶常绿矮林则以山地常绿阔叶林陆均松、琼崖柯、岭南青冈和油丹等种类的矮化为特征。植物群落Shannon-Wiener物种多样性指数分析表明,吊罗山植物群落物种多样性在空间的变化基本上表现为随海拔梯度增加而降低,次生林物种多样性最低,山地雨林和山顶矮林物种均匀度指数最高,群落优势种明显。
