盆中丘陵区生态恢复重建的生态与经济效益亟待提高

以紫色岩为背景的盆中丘陵区 ,是构建长江上游生态屏障的重点地区。近 10多年来 ,以林木植被恢复重建为主要内容的生态建设取得了显著成效 ,平均森林覆盖率已达到 2 2 %。但是 ,森林植被生态系统的生态与经济功能尚处于较低的水平 ,其中桤柏混交林生态系统开始出现退化的趋势 ,纯柏林面积日趋扩大 ,病虫害逐年增多。为此需应用生态学和经济学原理 ,实施农村生态经济工程建设的途径 ,把该地区生态建设推向一个新的水平。     

西藏羌塘中央隆起区物质组成与构造演化

对羌塘中央隆起区的物质成分及构造演化规律的认识 ,涉及到青藏高原特提斯演化、羌塘盆地的形成发展及高原的隆升过程。对羌塘中央隆起区构造演化在认识上目前有较大分歧 ,主要有两种观点 :1)认为扎布 (察布 )—查桑地区发育裂谷 ,没有发育成特提斯洋盆 ;2 )龙木错—双湖 (—澜沧江 )古特提斯缝合带 ,代表古特提斯洋的闭合遗迹之一。基于对羌塘中央隆起区物质成分及属性 ,以及同位素年代学研究 ,将羌塘中央隆起中泥盆世—早白垩世的构造发展历史划分了六个阶段 ,即D2 —C11初始裂谷阶段 ;C21—C2 裂谷阶段 ;P1海底扩张—大洋化阶段 ;P2 —T2 板块汇聚—消减阶段 ;T3 —J1板块碰撞阶段 ;J2 —K1碰撞—整体抬升阶段。羌塘中央隆起构造演化经历了一个完整的威尔逊旋回     

安徽巢湖—滁州地区中生代构造变形特征

安徽巢湖—滁州地区位于张八岭冲断带的南东侧 ,中生代构造活动十分强烈。早印支期 ,区内以北东—北北东向褶皱和逆冲推覆构造变形为特征 ,形成区内主体构造格架 ,为下扬子构造带的组成部分 ;晚印支期以近南北向挤压作用为主 ,形成北西西—近东西向叠加褶皱构造。燕山期 ,受郯庐断裂构造活动的影响 ,区内断裂活动加剧 ,形成多期不同性质的脆性断裂及其所控制的沉积盆地 (拗陷 )。

Variations in chemical compositions of the eolian dust in Chinese Loess Plateau over the past 2.5 Ma and chemical weathering in the Asian inland

Major and trace elements as well as strontium isotopic composition have been analyzed on the acid-insoluble (AI) phase of the loess-paleosol sequence from Luochuan, Shaanxi Province, China. Results show that the chemical composition of AI phase of loess and paleosols is distinctive to the average composition of upper continental crust (UCC), characterized by depletion of mobile elements Na, Ca and Sr. The distribution pattern of elements in AI phase reveals that initial dust, derived from a vast area of Asian inland, has suffered from Na- and Ca-removed chemical weathering compared to UCC. Some geochemical parameters (such as CIA values, Na/K, Rb/Sr and⁸⁷Sr/⁸⁶Sr ratios) display a regular variation and evolution, reflecting that the chemical weathering in the source region of loess deposits has decreased gradually since 2.5 Ma with the general increase of global ice volume. This coincidence reflects that the aridity of Asian inland since the Quaternary is a possible regional response to the global climate change.     

Anisotropy of the apparent resistivity variation rate near the epicentral region for strong earthquakes

IntroductionThe geo-electrical anisotropy before earthquake is of special significance for the prediction of earthquake location and for the research on crustal stress status near the epicentral region. The anisotropy has been studied from various aspects (CHEN, et al, 1983; QIAN, et al, 1985, 1996; LU, et al, 1990a; MAO, et al, 1995; RUAN, et al, 1999). But the anisotropic phenomena presented by geo-electrical data are not practically satisfactory and not clear as compared with the res…     

For a Europe of flexible regions and not of region-states divided by ethnicity

Discussion of the future of Europe continues to be a marginal political issue, partly because of the resistance of states, on both the practical (bureaucratic) and conceptual levels, created by the government leaders and heads of state. In turn, the nation-states are challenged from within by independent and separatist movements that have laid bare the fundamental hypocrisy of rhetorical discussions of the principle regarding the self-determination of peoples; interfering with states (and their borders) has proven to be a taboo for Europe. The growing flexibility of the globalised economy should be paralleled by a growing flexibility in the conception of the division and political organisation of territory, but this is not the case. Further inflexibility stems from the socio-economic inequity that we accept in our daily lives as normal, in particular as regards inequality in the use and division of territory. Equality, or better egaliberté (equality and liberty), is a sufficiently dynamic and flexible concept to be taken as a point of reference in envisaging the society, Europe, and world of tomorrow. It is only through the concept of egaliberté that we can imagine a Europe based on relations between regions that are conceived and organised on multiple scales and not as region-nations conceived on the basis of ethnicity or in the name of supposed cultural homogeneity.

河套华北地区旱涝的前期环流异常与大西洋海温的关系及其数值模拟

首先分析了河套华北地区旱涝的前期异常环流，然后探讨了这种异常环流形成的机制，最后采用了ＯＳＵ－ＡＧＣＭ作了大西洋地区热源异常强迫的数值试验。结果表明，大西洋地区海温异常强迫激发的定常波向上、下游的能量传播，造成的前期秋冬季环流异常与河套华北地区的夏季旱涝有较好的对应关系。
