The main tectonic events and climatic changes which occurred in the last 3Ma coincide with the Earth's orbital eccentricity changes having a period of about 0. 4Ma. The boundaries of tectonoclimatic cycles determined from the stratigraphic records in the Loess Plateau giving solar calendar ages of 0. 07, 0. 46, 0. 83, 1. 32, 1. 70, 2. 08, 2. 47MaBP respectively correspond to the time intervals where there is a decrease of the eccentricity of the Earth's orbit. Also,the basic data concerning the change of speed in the Earth's revolution and its possible effects on the Earth's rotation and on the interaction between the individual geospheres have been analysed. That the changes of eccentricity of the Earth's orbit may have resulted in a driving force for tectonic movemants is discussed. Finally, it is also pointed out that a study of the tectonoclimatic cycles is of importance for further development of the geomechanics theory.

最近3Ma发生的主要构造运动和气候变化事件,在准0.4Ma周期上与地球轨道偏心率变化存在一致性。据黄土高原地层记录划分的构造气候旋回界限,日历年龄分别为0.07、0.46、0.83、1.32、1.70、2.08、2.74MaBP,对应于偏心率曲线波动幅度由大变小时段的特定转折位置。文中分析了地球公转运动变速的基本数据及其对地球自转运动和圈层相互作用的可能影响,探讨了轨道偏心率变化对构造运动的驱动机制,并指出了构造气候旋回研究可为地质力学理论发展展示良好的前景。

,There is a wide distribution of the vermiculated red soil in the middle and lower reaches of the Changjiang River.A preliminary study of the Changhongdadao profile in Jiujiang City was carried out in this paper.In the profile,the strata can be divided from the bottom upwards into fluvial sandy gravel,horizontally vermiculated ferruginous red soil,vertically vermiculated red soil,red clay and eolian Xiashu loess,3.3m,4.5m,5.9m,3.6m and 41m thick respectively.The boundary between the Brunhes normal zone and the Matsuyama reversed zone is know from magnetostratigraphic study to occur in the middle part of the vermiculated red soil bed at a depth of 12.9m and the Jaramillo normal subzone in the ferruginous vermiculated red soil bed at a depth of 15.1m to 16.1m.The average sedimentation rate is calculated by Cande and Kent's palaeomagnetic age model and by thermoluminescent dating and hence the age of bed boundaries.The results show that the ferruginous vermiculated red soil was deposited during 1.232-0.869MaBP,the vermiculated red soil during 0869-0.392 MaBP and the red soil during 0.392-0.101MaBP. The sedimentary sequence in the Changhongdadao profile indicates a periodic climate change of about 0.4Ma.It is consistent with the tectonoclimatic cycles as revealed by the tectonic layers in the Loess Plateau and the Qinghai Tibetan Plateau and the change of the earth's orbital eccentricity.

长江中下游地区广泛发育网纹红土。本文对九江长虹大道剖面进行了初步研究。该剖面地层自下而上可分为河流相冲积砂砾石、以发育水平状网纹为特征的铁质网纹红土、以垂向网纹为特征的网纹红土、红色粘土和风成下蜀黄土,分别厚3.3、4.5、5.9、3.6和4.1m。磁性地层研究结果,布容正向极性带/松山反向极性带的界限出现于网纹红土层中部,距顶深部12.9m处;贾拉米洛正向极性亚带出现在铁质网纹红土层中,距顶深度15.1—16.1m处。根据CandeandKent古地磁极性年表的模式年龄和热释光年龄,计算出沉积速率,进而计算出各层的界限年龄。结果表明,铁质网纹红土沉积于1232—869kaBP;网纹红土大约沉积于869—392kaBP;红色粘土沉积于392—101kaBP。九江长虹大道剖面代表了该地区从河流沉积、铁质网纹红土、网纹红土、红色粘土到风成黄土沉积的演变过程,并显示出准0.4Ma的周期变化。这与黄土高原、青藏高原构造层和地球公转轨道偏心率变化所反映的准0.4Ma构造气候旋回基本一致

Volcanic activities are always accompanied with a large scale of tectonic activities .The most explosive periods are almost consistent with most active periods of tectonicmovements. Meantime the tectonic-volcanic activities are related to a large areal orglobal climatic changes.After collision between india and Eurasia Plates, occurred during about in 45-10MaB. P., there were a large volume of intermediate-acidic rocks in Gangdisi,southern Tibet during the same period. The another upsurge of volcenic activities generated during about 37~ 35MaB.P. There are a large volume of volcanic rocks inTibetan Plateau and eastern continental rift are4 respectively , correlating with a largescale of tectonic movement in 37- 35MaB.P. It is not only style change of volcanicactivities at 0.73MaB. P. but also rapidly climatic change occurring at 0.8MaB. P.Volcanic activities stabed at 0.73MaB. P. in many areas, such as Ashikelo volcanic eruption and Datong volcanic eruptions etc. which started to enter the upsurges ofvolcanic activities , and about meantime several other volcanic eruptions were nearceased .In thes paper, the volcanic activities of QUaternary in China were correlated withglacial period / interglacial periods based on the data of volcaic rock ages. Theupsurges of volcanic activities of Quaternary in China including both Tibet andEastern continental rift system occurred during 1.50- 1.10MIB. p., 0.73- 0.20MaB. P.,0.12- 0.07MaB. P. and 0.01 - 0MaB. P. respectively . They were mainly correlated withthe four interglacial periods, respectively . In Quaternary , most of volcanic eruptionsgenerated during interglacial periods in China.1.50- 1.10MaB. P. belongs to Longgang volcanic astivity episode which is thefirst upsurge of volcanic eruptions in Quaternary in China, forming volcanic rocks distributed in Xiaoyizishan Mountain, Longgang, Jiashan, Anhui Province. BaitoushanMountain volcanic activity episode that duration is 0.73- 0.20MaB.P. correlated withanother inter-glacial Period too. Those volcanic rocks formed during mis episode aremainly distributed in both continental rift system of northeastern China, northern Chinaand continental margin of southeastern China and northern Tibetan Plateau.Jinlongdingzi volcanic activity episode occurred during the episode 0.12- 0.07MaB.P.,which correlated also with the last interglacial Period. The volcnic rocks related withthes episode are mainly limited in the regions of Jinlongdingzi area of Longgang Quaternary volcanic field, Changbaishan Mountain, Leiqiong, and Tibetan Plateau.Holocene Wudalianchi volcanic episode consists mainly of all of the active volcanoesin China, for example Tengchong, Changbaishan Mountain, Wudalianchi, Longgang volcanic field, and some of northern Tibetan Plateau.A large amount of stratospheric aerosols provided by volcanic eruptions coulddramatically attenuate and decrease the direct solar beam, meantime , a concomitant increase in down-ward-scattered radiation finally causes relatively small decline in totalsolar radiation . This is reason why large explosively volcanic eruptions could declinethe surface temperatUre about lasting two to three years after volcanic eruptions.bee explosively volcanic eruptions could increase precipitation because volcanic aerosols ejecting into stratosphere might act as cloud condensation in stratosphere andvolcanic eruptions could suPPly a large amount of warer into stratosphere . Volcanic erUPtions might influence in surface pressure through changing the temperature of bothstratosphere and troposphere.

火山活动是一种重要的地质现象,它的发生总是与构造运动相关联,构造运动有强有弱,持续时间有长有短,具有旋目性,火山活动同样也具有旋回性。大规模的火山喷发往往会对气候变化产生影响,而影响的程度取决于火山所处的位置和喷发的性质及程度。强烈的火山喷发将造成局部地区乃至全球气温下降,由此人们推测火山喷发多发生在冰期,然而统计资料表明,绝大多数火山喷发发生在间冰期,此时的构造运动也比较活跃,而在冰期时很少有火山喷发。至于火山喷发后在短时间内造成的降温与长时间的冰期不能相提并论。火山活动有旋回性,它影响的气候变化也具备有旋回性,这是构造气候旋回的一种表现形式。
