新疆哈密地区地震地质及地震活动性

通过对哈密地区几大活动断裂带、历史地震以及近30年中、小地震活动性的分析，认为哈密地区同时受到南部印度－欧亚板块的碰撞作用与北部西伯利亚－蒙古地区地壳运动的影响，其构造运动兼具西部天山地区和北部蒙古－阿尔泰地区的构造运动的特点，即块体比较完整，只发育大断裂，大断裂之间的中、小断裂不很发育。这种特殊的地震地质和地球动力学环境，决定了哈密地区历史和现今地震活动的特点为：大震复发周期长，低b值，中、小地震活动水平较低等。     

The Upper Permian Sedimentary Facies and Its Role in the Dajing Cu-Sn Deposit, Linxi County, Inner Mongolia, China

Abstract: Exhaustive investigations were launched for confirming the upper Permian host rocks of the Dajing Cu-Sn Deposit, probing into the possibility that Dajing is a Sedex type deposit during cosedimentation, complementing the deficiency of previous researches and going further into substantiating the role of the upper Permian strata in the control of ore distribution. After more than two years work, we reclassified the sedimentary facies in the Dajing area and its periphery as shallow fresh water lake and delta. Indicative sedimentary structures, such as ripple marks, rain marks, and mud cracks combined with contemporary fossils, were revealed. Having measured the flow directions, performed chemical comparison, and analyzed various sediments from sourceland in the Dajing area by XRF, we consequently redivided the strata into four sedimentary members, among which P₂l₁ and P₂l₂ were concluded as significant ore-hosted strata. The upper Permian basin was a lateral rift basin. The water and sediments in the basin are much deeper and thicker in the north than those in the south.
The indicators of special sedimentary facies, such as gravity flow, brine pool and synchronogenic stratiform structure of the ore cannot be found in the Dajing area. There was no growth fault, assemblage of sulfide and sulfate, and no zonation as well.
On the basis of study in this area, taking into account the paleosedimentary environment as capriciously flowing shallow lake, which approximated the state of oxidation, we figured that the paleogeography made it prohibitively difficult to form stratiform sulfide deposits which are prone to form in deoxidized environment. It can be ruled out the possibility that the Dajing deposit is a syngenetic deposit during sedimentation.     

Gottmann's Geographic Glossa

At a time when human geography–in its search for general and systemic laws–was often seduced by different kinds of determinism, Jean Gottmann developed his theoretical model in order to explain the political partitioning of geographical space. This model, shaped by the study of the classics in political philosophy, makes explicit reference to human psychology, and is based on a few fundamental concepts: cloisonnement (partitioning), circulation (movement), carrefour (crossroad) and iconographie (iconography). This paper presents the above mentioned concepts through a chronological analysis of their formulation in different chapters of Gottmann's bibliography, in order to reconstruct the genesis and evolution of his model. In the conclusions a few questions are presented, that suggest how Gottmann's model could still be usefully applied to contemporary human and political geography.     

用航摄像对制作全息地形立体图的新技术

全息地形立体图是将传统的光学机械立体投影术与全息术相结合，用航摄像对合成为一张具有一定焦深的近像面全息图。它既具有像面全息图衍射效率高，可以用扩展的白光光源再现的优点，也具有体全息图一定的波长和角度选择性。本文介绍了拍摄这种立体图的装置和方法，并从理论上对实验结果进行了一些分析，最后指出了它的应用前景。     

河北磁县北西西向南山村－岔口活动断裂带活动特征与1830年磁县地震

河北磁县西部北西西向南山村－岔口活动断裂为北西西向磁县活动断裂西段，全长３５ｋｍ，又可再分为东西两段。全新世时期该断裂有多次活动，活动方式以具左旋性质的正倾滑为主。１８３０年磁县７．５级地震时，南山村－岔口断裂带出现新的地表破裂，地表垂直位移多处为２～４ｍ，最大约７ｍ。据目前资料，该断裂带最新两次地震事件的时间间隔约为３５００ａ。最近获取的位于磁县最高峰老爷山庙宇碑文资料，补充说明了邻近岔口活动断裂带的古建筑物在１８３０年地震中的严重破坏。     

长江三角洲南部“大城市圈振兴”理论的质疑

工业发展和城市化的传统理论，对亚洲的某些具有较高生产力水平，且还在发展中的“大城市圈”不能充分地解释，本文对长江三角洲南部空间经济转为的“大城市圈振兴”理论进行了批判地评论，根据最新的现场调查结果，从根本上对“转为过程”的假说提出质疑，并且提出了更适当的的区域发展战略，此外还证明，关于亚洲大城市带的一般结论，必须建立在对地方性经济变革认识的基础之上。     

军事地理学的“三原素”基础与“军一地”关系理论

本文提出军事地理学的“三原素”基础和“军—地”关系理论。前者论述军事地理学的全部内容均源于环境(地理)、战争(军事)、人(成员、活动)三个基本因素的存在和作用;后者论述由主导性原则、依赖性原理、制约性原理、综合效应原则和间接军力原理等组成的“军—地”关系理论。     

Use of the mantle magnitudeM m for the reassessment of the moment of historical earthquakes

The mantle magnitudeM _m is used on a dataset of more than 180 wavetrains from 44 large shallow historical earthquakes to reassess their moments, which in many cases had been previously estimated only on the basis of the earthquake's rupture area. We provide 27 new or revised values ofM _o, based on the spectral amplitudes of surface waves recorded at a number of stations, principally Uppsala and Pasadena. Among them, and most significantly, we document a large low-frequency component to the source of the 1923 Kanto earthquake: the low-frequency seismic moment is 2.9×10²⁸ dyn-cm, in accord with geodetic observations. On the other hand, we revise downwards the seismic moment of the 1906 Ecuador event, which did not exceed 6×10²⁸ dyn-cm.Finally, the study of the 1960 Chilean and 1964 Alaskan earthquakes whose exceptionally large moments are properly retrieved throughM _m measurements, serves proof that this approach performs flawlessly even for the very greatest earthquakes, and is therefore successful in its goal to avoid the saturation effects plaguing any magnitude scale measured at a fixed period.
