基于AHP和GIS的扬泰地区浅层地下水脆弱性评价

地下水脆弱性评价是保护地下水资源的重要手段,本文根据扬泰地区浅层地下水的水文地质条件,对DRASTIC模型进行了修改。选取地下水位埋深、大气降水入渗净补给量、含水层介质、含水层厚度、地形坡度、包气带介质影响、含水层富水性7个因子作为评价因子,利用层次分析法确定各因子的权重值,建立了符合扬泰地区浅层地下水脆弱性评价模型;利用ArcGIS10．0软件的空间叠加分析功能,编制了扬泰地区浅层地下水脆弱性评价等级图,评价结果与该地区实际水文地质条件基本吻合,对扬泰地区的地下水资源保护和区域规划具有一定的参考价值。     

泰山南坡第四纪沉积物石英砂表面特征及沉积环境指示

为考察泰山地区第四纪沉积环境,采用石英砂表面特征分析法,采集泰山南坡第四纪沉积物样品,经观察研究后,随机挑选W₁～W₆共6颗石英砂颗粒进行扫描电镜观察。除W₄外,其余颗粒表面均表现出形态不规则、边缘棱角清晰、具有多样的贝壳状断口和解理片特征,该特征所指示的沉积环境为冰川沉积环境条件。沉积物样品热释光测得年龄为30.54±2.59 ka B．P．与末次冰期主冰期时段具有时间上的吻合性。     

凸起凹陷构造控矿及找矿探讨——以泰安市区为例

在泰安市所辖6个县市区范围内,分布着以铁、金等为主的金属矿产和以煤、石膏等为主的非金属矿产。两类矿产分别赋存于呈近SN向相间排列的5个凸起和5个凹陷构造中,铁、金等矿赋存于凸起,煤、石膏等矿赋存于凹陷。对凸起构造特征分析认为,南北方向相邻的凸起、凹陷构造本是一体,凹陷深部与凸起有相似的地质条件,相似类比理论为地质找矿工作提供了空间,应树立综合找矿和缺位找矿的思想,整合矿业权,实行整装统筹勘查。     

Tree population dynamics of three altitudinal vegetation communities on Mount Cameroon (1989�C2004)

Changes in permanent sample plots in the lowland,submontane and montane forests on Mount Cameroon(4,095 m above sea level),an active volcano,are described for 15 years from 1989 to 2004.Throughout the study period,the stocking level of trees with a diameter at breast height(DBH) ≥ 10 cm in the three forests were lower than in pan-tropical stands suggesting a significant impact of volcanic and human-related activities on the vegetation communities on the mountain.Annual mortality rates in the submontane and montane forests were consistent with those reported for comparable altitudinal ranges in the Blue Mountains of Jamaica.The annual mortality rate was higher in the lowland forest than other lowland sites included.Divergence between recruitment and mortality rates was large suggesting that the three vegetation communities have not reached their climax.The seven-year difference in half-life of large trees(with a DBH ≥ 50 cm) in the submontane and montane forests suggests an altitudinal effect on turnover of larger trees that in turn contributes to the frequent small stature of high altitude forests.There was little evidence of an altitudinal effect on species turnover and growth rate.This finding supports generalizations about the zero effect of growth on the stature of high altitude trees.Understanding forest dynamics is crucially important in the management of tropical montane environmentsand in this instance particularly so given the recent creation of the Mount Cameroon National Park.     

Cordierite-anthophyllite rocks from north-west Queensland, Australia: metamorphosed magnesian pelites

Abstract Cordierite-anthophyllite rocks and related cordierite-rich, talc-rich and chlorite-rich rocks occur in the Rosebud Syncline, north-west Queensland, Australia, as part of a Proterozoic metasedimentary sequence. Field relations and rock compositions attest the sedimentary origin of these rather unusual metamorphic rocks. Their chemical composition is comparable to that of unmetamorphosed, alkali- and Ca-poor pelites, which are associated with some evaporite deposits. Other occurrences of cordierite-anthophyllite rocks have commonly been interpreted as metamorphosed chloritic alteration products derived from mafic or felsic volcanics. A comparative chemical study, using analyses of cordierite-anthophyllite rocks from such alteration zones and analyses of unmetamorphosed magnesian pelites, demonstrates the general chemical similarity between these two rock groups of entirely different origin. However, distinct differences in major element relations help to distinguish these two genetic groups. Particularly useful are Al₂O₃–FeO–MgO plots, in which evaporitic pelites occupy the Fe-poor side. The highly magnesian metamorphic rocks from the Rosebud Syncline fall entirely into the compositional field of evaporitic clays and shales. Furthermore, analyses of relatively immobile trace elements give supporting evidence for the sedimentary origin of these cordierite-anthophyllite rocks. The correlation with trace element ranges of clays and shales is very good. However, the correlation with trace element ranges of mafic and felsic volcanics is poor, and major discrepancies occur with Cr, Ni, Co, Nb, Sc, Th and Ti. Thus, the magnesian metamorphics of the Rosebud Syncline appear to be derived from evaporitic clays rich in magnesian clay minerals, such as palygorskite, sepiolite, chlorite or corrensite. The complete metamorphic rock assemblage of interlayered calcareous, aluminous and magnesian rocks is interpreted as a metamorphosed carbonate-evaporite-pelite sequence.

The Contribution of the Cartographic Visualisation in Understanding the Historical Geography of an Old Land Property Regime in Mouth Athos (Karyes)

Abstract

title/>

The peninsula of Mount Athos is the largest monastic gathering of Modern Orthodoxy in the world, operating continually under the same regime since 883 AD. Focusing on Mount Athos, this paper attempts to examine the spatial regime continuation and identify the relation to what is considered to be a small residential unit around a central church (Protatos) within the limits of the Athos peninsula. The paper investigates the delimitation of the area, mapping and recording the relevant changes cartographically. At the same time, the paper creates a cadastral plan of the present regime, recording real estate owners in a cadastral table. Finally, the paper focuses on the significance of the findings to the historical geography of Athos, as well as the emergence of a new ‘area’, added to the twenty monasteries of the peninsula after 1450.     

Water quality and light absorption attributes of glacial lakes in Mount Qomolangma region

As they are products of glacier movement, the water body composition and water quality attributes of glacial lakes have distinct characteristics compared with inland lakes. Although satellite remote sensing provides an effective approach to monitor water quality, lack of in-situ measurement data on the status and environment surrounding glacial lakes presents a major constraint in relating satellite data to water quality indicators. This study presents findings of a preliminary investigation into water quality attributes of 3 glacial lakes in the Mount Qomolangma region. Suspended particulate matter （SPM）, light absorption attributes of phytoplankton, nonalgal particles （NAP）, and colored dissolved organic matter （CDOM） were measured. The suspended substance concentration varies markedly from 0-320 mg/L. This is considered to reflect differing stages of lake development. l-he chlorophyll concentra- tion is much lower than that found for inland lakes, as landscapes that surround these high altitude lakes have almost no vegetation growth. The phytoplankton and CDOM concentration depend on long-term stability of lake slopes. Given the lack of exogenous and endogenous inputs in the Qomolangma region, CDOM in glacial lakes is significantly lower than in inland lakes. These preliminary findings could support efforts to appraise estimates of water quality parameters using remotely sensed images.
