It is explained in this article that gravitational segregation is the motive force for the radial migration of calcium and magnesium in the earth's crust.Thus,an attempt is made to analyse the eo-proterozoic marine geochemical background,by considering the evolutionary rules governing aerosphere and hydrosphere.This leads to the authors'conclusion that the proterozoic era is most likely the high time for the formation of sedimentation deposit of magnesianite.This also explains the basic global geological phenomenon...

Although there seem to be many earthquake precnrsors,sudden occurrences of moderate and small earthquakes and sudden quiescence phenomena after their concentration can be mainly used at present in the decision making for short-imminent earthquake prediction.The attenuation features of earthquake sequences should he taken into consideration for predicting strong aftershocks.The static seismic hazards can be forecasted on the hasis of the response characteristics of the soil,depth of ground water table and topography etc.to ground shaking;the dynamic seismic hazards can be forecasted based on various precursors such as rise or fall of ground water Ievel,fault creeping,foreshocks,meteorological factors and so on.The experiences obtained from studies of historical large earthguakes in China indicate that small tremors take place prior to big shocks,and this is the,seismological evidence for the masses to seek shelter immediately prior to a large earthquake.The rapid determination of epicenters.magnitude and meizoseismal distribution of a large shock immediately after it occurrs is the key to rapid and best deployment of relief material and personael.The prompt identification of the meizoseismal distribution can be made by using the methods of seismo-geology, historical carthquake examples,precursory field,focal mechanism and direct reconnaissance and so on.In case,a large earthquake occurrs in a deeper offshore region,whether or not a tsunami will he caused therefrom could be judged from the ratio of the SV and components of the transverse waves and the ratio of amplitudes of two surface waves.The internal organs of the human body may easily get into resonance with the major values of the acceleration spectrum of earthquake waves;this fact should be taken into account when considering medical countermeasores.The methods of statistics,heat comduction and fault slip rate can be applied for estimating the intensity of future earthquakes in post-earthquake rehabilitation work.

地震学前兆虽然很多,但今日能用于短临预报决策的主要是中小地震的突然活跃以及密集后的突然平静现象。对于强余震的预报还要考虑到地震序列的衰减特征。静态震害预测基于土质、地下水深浅和地形等对振动的响应特征;动态震害预测基于前兆所反映的水位升降、断层蠕滑、前震和气象因素等。对我国历史上大震研究的经验表明,大振动前刻有小动,这是群众临震急避的地震学依据。大震发生后即迅速定出震中、震级和极震区分布是快速救灾和最佳部署物资和人力的关键。对于极震区分布的速判可用地震地质、史例、前兆场、震源机制和直接侦察等方法。如大震发生于较深的近海地区,则用横波 SV 和 SH 分量之比以及两种面波振幅之比判断有无海啸。地震波加速度谱中的较大值与人的胸部内脏易于共振,这是医疗对策方面要考虑的。在重建家园方面,可利用统计法、热传导法和断层滑动速率法确定抗震烈度。

The ecosystem is not a self-contained system,but it has close con- tact with external environment,or it can be said that ecosystem exists under a certain condition of the background.And hence,ecosystem has either interconnection with its developing process or constraint with external invironment.In order to have a better understanding of econo- gical features,it is not enough to know ecosystem itself but to under- stand its background of its existence.This paper summarily showed various aspects of Geoseience background of ecological environment. (1)It deals with ecological features of geomorphological environment from the following aspects,i.e.topographical function in formation of modern climate,relationships among topography and its evolution with climate and environmental evolution of surface runoff and drou- ghts and their effects upon formation of biologicaldistribution zonation evolution of biological community and soil formation and its develop- ment,etc.(2) Biological features mainly include parent materials and mother rocks/surface water/telluric magnetic force and geological history.This paper lays emphasis on the introduction of relationships among the inversion of telluric magnetic force and biological evolution as well as species eradication and relationship between geological hist- ory and soil ecology.

生态系统不是孤立封闭的系统,它和外部环境有密切的联系,或者说它是存在于一定的背景条件下的。因此,生态系统既有其内在的、自身的发展过程,也有其受外部环境制约的一面。要认识生态系统的特征,只从系统本身着眼是不够的,还需要对其存在背景有一定的了解。本文概括地说明了生态环境地学背景的诸方面:(1)生态特征的地貌背景,分别从地形在现代气候形成中的作用;地形及其演化与气候及地表水旱环境演化的关系,对生物分布区形成的影响,对生物种群演化及对土壤形成发育的影响等方面作了论述。(2)生态特征的地质背景,主要包括母质和母岩、地下水、地磁及地质史等几方面,本文着重介绍了地磁倒转与生态演化及物种灭绝的关系、地质史与土壤生态的关系。
