晚太古代Sanukite（赞岐岩）与地球早期演化

Shirey and Hanson(1984)将某些太古代的高镁闪长岩套称为sanukite(赞岐岩),类似于日本中新世(11～15Ma)Setouchi火山岩带的高镁安山岩。Sanukitoids由闪长岩-二长闪长岩-花岗闪长岩组成,不同于TTC岩套(奥长花岗岩-英云闪长岩-花岗闪长岩)。Sanukitoids具有下列地球化学特征:富Mg,Mg~#>0.60,Ni和Cr>100μg/g,Sr和Ba>500μg/g,LREE富集(大于球粒陨石100倍),无Eu异常。高镁安山岩在太古代很少见,而其相应的侵入岩高镁闪长岩或sanukitoids,虽然数量也很少,但却是各地晚太古代地体中随处可见的。Sanukitoids的原始岩浆是交代的地幔楔部分熔融形成的,随后可能经历了广泛的分离结晶作用。TTC和sanukitoids岩套可以相伴产出,二者均与板片熔融有关,TTG与其直接有关,sanukitoids可能与其间接有关。全球Sanukitoids主要集中在晚太古代时期,可能暗示板块的消减作用在～3.0Ga以后才起了重要的作用。     

内蒙古二连浩特市—东乌珠穆沁旗半干旱荒漠草原区区域化探方法试验

内蒙古二连浩特市-东乌珠穆沁旗地区属半干旱荒漠草原区.1∶20万区域化探扫面应针对该类景观区微景观特点,选择土壤或水系沉积物测量方法开展工作.经试验确定采样粒级为-5～ 20目;采样密度2个点/km2;采样介质为残坡积物或冲、洪积物.经4个1∶20万图幅的区域化探扫面工作,取得了明显的异常圈定和地质找矿效果,方法技术有效.     

内蒙古大青山地区构造新样式初探

内蒙古大青山地区侏罗纪盆地中发育有断层相关褶皱，有十分清晰的断层传播褶皱，断层转折褶皱等构造样式。断层相关褶皱轴向呈东西向展布，形成褶皱的地层是早侏罗世右拐群煤系地层，表明该褶皱至少在煤层形成后，受南北向挤压应力作用形成。研究这一构造样式，对这一地区的推覆构造、盆山耦合研究具有重要地质意义。     

金丽温高速公路K81高边坡变形动态数值分析

对金丽温高速公路K81高边坡进行接触大变形有限元动态数值分析.结果表明,路堑边坡开挖,导致滑面的法向应力减小、抗滑力下降,是引起古滑坡复活的根本原因.研究结果也说明了接触大变形有限元分析方法可以较好地分析潜在滑面的力学作用,是研究滑坡的滑动机理的有效方法.     

松嫩平原湿地植被对生境干-湿交替的响应

扎龙湿地和向海湿地水分布存在不均一性，生境中有“干-湿”交替过程。选取“干-湿”界面上沼泽植被与草甸植被共存的群落片断分别设置15个固定样方，生长季内4个月观测结果表明：扎龙湿地和向海湿地生境旱生化时羊草为优势种群，湿生化时芦苇为优势种群，芦苇沼泽群落和羊草草甸群落随生境“干-湿”交替过程相互演替，演替过程既受生境水分波动的影响，又由优势种群内在生物学特性决定。

Geographical distribution of ecological footprint and sustainability analysis for Liaoning Province

This paper presents the detailed results and analyses on the ecological footprints and bio-capacities of the individual cities and the province as a whole for the year 2001, providing a clear picture of sustainability for the province. Results show that the ecological footprints of most cities in Liaoning exceeded their respective bio-capacities, incurring high ecological deficits. The ecological deficit of the province as a whole was 1.31 ha/cap. Those cities with resources extraction and/or primary material-making as their major industries constitute the "ecologically black band", whose ecological deficits ranged from 2.45 to 5.23 ha/cap, the highest of all cities in the province. Fossil energy consumption was the major source of footprint amounting to 1.63 ha/cap at the provincial level, taking up 67.3% of the total. For cropland, modest ecological surpluses occurred in Jinzhou, Tieling, Huludao, and Panjin while modest ecological deficits in Dalian, Benxi, Fushun, and Dandong, resulting in an overall surplus for the province. Liaoning had a certain level of surplus in fishing ground (water area), mainly distributed in the coastal cities of Dalian, Panjin, Huludao, Yingkou, Jinzhou, and Dandong. Most cities had a small ecological deficit in pasture and all had a small ecological surplus in forest. The eco-efficiency, expressed as GDP value per hectare of footprint, exhibits high variations among the cities, with the highest (Shenyang) more than 10 times the lowest (Fuxin). Cities with manufacture, high-tech, and better developed service industries had high eco-efficiency, while those with resources extraction, primary material-making, and less developed service industries had low eco-efficiency. Based on the components and geographical distribution of ecological footprint, strategic policy implications are outlined for Liaoning's development toward a sustainable future.
