Applying the integrated analysis measure of geo-history and climate-tectonic cycle,and the RS technique demonstrates the controlling of Neotectonic movement to the form of saline-alkali soil. It indicates that the neotectonic movement offered the sources and transit approach to soda salinity in Songnen Plain and built up an environment for salinity congregation. Soda salinity was mainly enriched in the sedimentation area of Holocene basin centrally of which was the serious disaster area of modern soil salinization....

Applying the integrated analysis measure of geo-history and climate-tectonic cycle,and the RS technique demonstrates the controlling of Neotectonic movement to the form of saline-alkali soil. It indicates that the neotectonic movement offered the sources and transit approach to soda salinity in Songnen Plain and built up an environment for salinity congregation. Soda salinity was mainly enriched in the sedimentation area of Holocene basin centrally of which was the serious disaster area of modern soil salinization. As to the climate drying and warming up in Holocene,salt accumulating action broadly carried through,and multi-alkali soil was developed within 1.5 m from the surface. From the middle Holocene,vegetation and mantlerock were developed in the original alkaline meadow grassland,and formed a good overlay,which protected the eco-environment of the grassland. Along with the excess exploitation to the grassland and climate drying and warming up since 20th century,the soil has rapidly saline-alkalized.

应用地质历史与气候-构造旋回相结合的分析方法,并采用卫星遥感技术,研究、揭示新构造运动对盐碱土形成的控制作用。研究表明,新构造运动的作用与过程为松嫩平原提供了苏打盐份的来源和搬运途径,并营造了盐份的聚集环境。苏打盐份主要富集于全新世盆地的沉降区,沉降中心为现代土壤盐碱化的重灾区。自全新世以来,由于气候的干暖化,积盐作用广泛进行,在地表1.5m深的范围内,发育多层碱土。中全新世以来,在原始的碱性草甸草原上,发育了植被和土被,形成了良好的覆盖层,它们对草原生态环境起了保护作用。自20世纪以来,随着人类对草原的过度开发和气候干暖化,导致土地迅速盐碱化。

Based on the age dating,geochemical and geophysical analyses,as well as field investigation along the coast of South China Sea,the authors expatiated the characteristics of sedimentary facies,chemical components and susceptibility of the Zhanjiang Formation(Early Pleistocene) and the Beihai Formation(Middle Pleistocene),and showed the pictures of deformation,folds,faults,and volcanism in the area.It is indicated that there have occurred a series of tectonic events in the northern parts of the South China Sea...

Based on the age dating,geochemical and geophysical analyses,as well as field investigation along the coast of South China Sea,the authors expatiated the characteristics of sedimentary facies,chemical components and susceptibility of the Zhanjiang Formation(Early Pleistocene) and the Beihai Formation(Middle Pleistocene),and showed the pictures of deformation,folds,faults,and volcanism in the area.It is indicated that there have occurred a series of tectonic events in the northern parts of the South China Sea during the period from 0.9MaB.P. to 0.7MaB.P.,a mainly uplifting period with sedimentary source changed from continental-oceanic to continental,with an increasing of continental weathering and erosion,with a dropping of sea level,with volcanic explosion,and with the formation of fold,fault and unconformity.These events indicated a tectonic activity,which is similar to the records of other areas,such as the Loess Plateau,Tibetan Plateau,West China,North China,and East China.It is also suggested that the uplifting of the Tibetan Plateau by stages not only caused great changes to its own tectonics,landform,and climate,but also effected and forced the process of environmental changes in its adjacent regions as well as Chinese continent,even the whole of East Asia.We believe that this tectonic movement was controlled by the Coupled Climato-Tectonic System and followed the rule of the Climato-Tectonic Cycle.The forcing effects of the environmental change of Chinese continent are the exogenic-endogenic geodynamic process——the global tectonic system,the global climatic system and so on.

文章根据一系列野外调查和年代测定以及地球化学与地球物理测试分析,阐述了南海北部早更新世湛江组和中更新世北海组的沉积相、化学组分、磁化率等特征,并描述了该区构造变形、褶皱、断裂和火山活动特点。研究结果表明,本区在0.9~0.7M aB.P.的早-中更新世转换期间(中国第三大构造-地貌阶梯主隆起期)发生了一系列构造活动,导致了沉积相由海陆交互相向陆相的转变、大陆风化和剥蚀作用的增强、海平面急剧下降、火山强烈喷发以及褶皱、断裂和不整合面的形成。这种事件群发性所指示的构造活化与中国大陆其他地区的记录相似,例如,黄土高原、青藏高原、华北、华东和西部;同时指示,青藏高原的阶段性隆升不仅导致其自身构造-地貌-气候的剧变,而且引起了周边地区乃至中国和东亚大陆环境的剧变。这种构造运动可能是在气候-构造旋回的规律下,受气候-构造耦合系统的控制,即受内外动力系统的控制,或全球构造系统和全球气候系统的控制。
