基于"区域分解"思想的苏锡常地区地面沉降相关预测模型研究

本文在系统分析苏锡常地区地下水开采与地面沉降发展动态及相互关系的基础上,从“区域分解”的思想出发,将研究区按第四纪土层结构进行了合理分区,并分别在各亚区建立地面沉降量与地下水水位相关预测模型。实践表明,该模型符合现阶段苏锡常地区地面沉降研究现状,具有一定的实用价值。     

An investigation of analysis of variance as a tool for exploring regional differences in strong ground motions

The statistical technique known as analysis of variance is applied to a large set of European strong-motion data to investigate whether strong ground motions show a regional dependence. This question is important when selecting strong-motion records for the derivation of ground motion prediction equations and also when choosing strong-motion records from one geographical region for design purposes in another. Five regions with much strong-motion data (the Caucasus region, central Italy, Friuli, Greece and south Iceland) are investigated here. For the magnitude and distance range where there are overlapping data from the five areas (2.50 M_s 5.50, 0 d 35 km) and consequently analysis of variance can be performed, there is little evidence for a regional dependence of ground motions. There is a lack of data from moderate and large magnitude earthquakes (M_s > 5.5) so analysis of variance cannot be performed there. Since there is uncertainty regarding scaling ground motions from small to large magnitudes whether ground motions from large earthquakes are significantly different in different parts of Europe is not known. Analysis of variance has the ability to complement other techniques for the assessment of regional dependence of ground motions.     

近4万年渤海西岸海侵时古海面的现代标高对比研究*

近4万年以来,相应于两次高太阳辐射暖湿期渤海西岸曾经两次海水泛陆事件,即40~28kaB.P.与10~4kaB.P.海侵事件。文章基于众多钻孔海相层中有孔虫、介形类等海相微体生物化石的组合特征恢复海水深度,重建了海侵最大时的古海面的现代标高。结果显示: 40~28kaB.P.海侵,海面的现代标高最高可达-11~-5m;10~4kaB.P.海侵则为2~3m。后者同众多研究所认为的中全新世存在高海面,海面高度为2~3m的结论大致吻合,前者则与全球气候尚处在间冰阶,冰川部分消融,世界洋面处在-50m的大背景不协调。而辽东与山东半岛沿海众多钻孔揭示,40~28kaB.P.渤海地区并没有高于-50~-20m海面存在的证据。通过区域环境的综合分析,认为40~28kaB.P.渤海西岸的海侵,是早玉木冰期持续4~5万年之久的冰期低海面环境,这种特殊的环境使现代渤海西岸的大部分区域远离沉积环境,成为冲刷侵蚀区,这种效应叠加在冰期边缘海式构造下沉与弧后盆地性质的构造下沉背景之上造成区域性异常地面低洼;渤海西岸异常地面低洼在间冰阶全球趋暖,冰川型海侵的过程中形成的区域性强烈"视"海侵(指示当时海侵时海水深度很大,而不是海水的陆泛范围大)。

Migration Within Mexico: A Data-based Exercise for Secondary Students

Abstract

People have been leaving rural environments and moving into urban environments. By 2007, the most people in the world will live in cities (United Nations 2002). Mexico illustrates this world trend closely. Mexico now publishes data on the Internet that can be used to study the movement of people within the country. A lesson is presented with selected new data connecting regional migration and job opportunities. Students create choropleth maps, analyze patterns, and make generalizations about patterns and processes.     

青藏高原江河源区近40年来气候变化特征及其对区域环境的影响

以江河源区12个气象台站1971-2008年间的逐月气温、风速和降水资料为基础,对该区气候变化特征进行了分析,结果表明:近40年来,江河源区气候持续变暖,年均气温的增温率为0.37℃/(10 a),1987年和1998年气温由低向高突变;年均风速显著降低,每10 a降幅为0.24 m/s,1981年和1992年风速由高向低突变,年均风速与年均气温间呈负相关关系;1980年代降水偏多,1970和1990年代偏少,21世纪以来降水量有所回升,增幅因区域而异;年陆面蒸发量整体显著增加.结合前人研究,探讨了气候变化对环境的影响:持续升温导致江河源区内冰川退缩、多年冻土退化;1980年代气候相对暖湿,水资源量较丰;气候暖干化、水资源量减少、生态环境恶化是该区在1990年代和21世纪最初几年的显著特征;2004年左右以来,江河源区气候转湿,水资源量增加,生态环境有所好转.     

近50年来淮河流域极端降水的时空变化及统计特征(英文)

Based on the daily precipitation data of 27 meteorological stations from 1960 to 2009 in the Huaihe River Basin, spatio-temporal trend and statistical distribution of extreme precipitation events in this area are analyzed. Annual maximum series (AM) and peak over threshold series (POT) are selected to simulate the probability distribution of extreme precipitation. The results show that positive trend of annual maximum precipitation is detected at most of used stations, only a small number of stations are found to depict a negative trend during the past five decades, and none of the positive or negative trend is significant. The maximum precipitation event almost occurred in the flooding period during the 1960s and 1970s. By the L-moments method, the parameters of three extreme distributions, i.e., Generalized extreme value distribution (GEV), Generalized Pareto distribution (GP) and Gamma distribution are estimated. From the results of goodness of fit test and Kolmogorov-Smirnov (K-S) test, AM series can be better fitted by GEV model and POT series can be better fitted by GP model. By the comparison of the precipitation amounts under different return levels, it can be found that the values obtained from POT series are a little larger than the values from AM series, and they can better simulate the observed values in the Huaihe River Basin.     

Rural and gender studies: A conceptual comparison

The aim of this article is to describe the noticeable similarities in the development of rural research and geography-close gender studies. Both research fields have developed greatly since 1970. Rural research has its roots in geography, while models and theories in gender research emanate from other disciplines. This article primarily treats the development of Nordic research and describes the development and different phases of each research field. The purpose is to draw attention to the parallel routes of development that characterize these fields, although in Swedish research they have not influenced each other much. Rural gender research, an area where the two research fields are interrelated, is the one exception. This focus, mainly developed by feminist geographers, has been largely invisible within the mainstream of both fields and has probably hindered new paths of development. Finally, I describe a route towards the development of a gender research based on the concept of space influenced by both fields of research.     

Finding the Southern Part of Cyberspace: Using the Internet to Teach the South

Abstract

This article suggests how teachers can approach the Internet conceptually and use it practically as they teach about the American South. Because of its information, communication, and cultural dimensions, the Internet represents a “place” where students and teachers can appraise the South from multiple, alternative perspectives. The article offers lesson strategies and resources for both on-computer and off-computer classroom settings. By finding the southern part of cyberspace, the authors illustrate that regions can and do have a place in a medium often represented as spaceless and devoid of geographic boundaries.
