On crustal movement in Mt. Qomolangma area

Mt. Qomolangma lies in the collision zone between the fringe of Eurasia plate and Indian plate. The crustal movement there is still very active so far. In the past three decades China carried out five geodetic campaigns in Mt. Qomolangma and its north vicinal area, independently or cooperatively with other countries, including triangulation, leveling, GPS positioning, atmospheric, astronomical and gravity measurements. On the basis of the observation results achieved in the campaigns the crustal movements in the area were studied and explored. A non-stationary phenomenon both in time and space of the crustal vertical movement in the area is found. There seems to be some relevance between the phenomenon of non-stationary in time and seismic episode in China. The phenomenon of non-stationary in space is possibly relevant to the no-homo- geneity of crustal medium and non-uniform absorption of terrestrial stress. The horizontal crustal movement in the area is in the direction of NEE at a speed of 6–7 cm per year, and the trend of strike slip movement is manifested evidently in the collision fringe of Indian plate and Qinghai-Xizang block.     

阿拉尔灌区棉田蒸散量计算模型

根据2000年阿克苏水平衡站有底测坑试验资料，分析了土壤水分有效性函数与土壤相对有效含水率，作物生物学特性函数，与群体叶面积指数的关系，结果表明：（1）土壤水分有效性函数与土壤相对有效含水率呈直线函数关系；（2）作物生物学特性函数与群体叶面积指数呈指数函数关系。选用20cm蒸发器水面蒸发量、作物生物学特性函数和土壤水分有效性函数，应用数理统计方法建立了阿拉尔灌区棉田蒸散量计算模型。该模式仅需常规气象与土壤湿度资料，计算简便，精度较高，便于在缺乏实测资料的地区使用。     

两千多年前广州古城区有过半岛和河汊吗--与《广州秦汉考古三大发现》作者商榷

从第四纪地质学及历史地貌学出发，对《广州秦汉考古三大发现》一书中提出的，在2100多年前广州古城区曾经出现过东、西半岛和古河汊地貌表示怀疑。据当时的古地理环境看，古代南越国王宫遗址的建筑是在已干涸的陆地之上进行的，而王宫建筑底部的本质结构是一种建筑基础措施，而非“造船工场（船台）”。     

塔里木河下游地下水位与水化学成分关联度排序分析

根据2001年塔里木河下游第四次生态输水前后地下水位、水质变化的监测和取样分析资料。运用灰色关联分析法。对塔里木河下游地表生态输水前、后的地下水位与地下水化学成分进行了关联分析。分析研究表明，生态输水对地下水质的影响比较明显。在关联排序中。阴离子的SO4^2-、Cl^-以及阳离子的Ca^2 、Mg^2 与地下水位变化的关联性较强；pH值与地下水位的关联度最低。仅为0．534；矿化度与地下水位关联度最高,达到0．863。     

试论少数民族地区的生态化旅游开发

生态化旅游开发是有别于传统的旅游开发的一种可持续开发与发展的理念，它追求的是生态、社会和经济综合效益的最大化，应该成为旅游开发与旅游业发展的主要方向。民族地区的旅游开发具有特定的区域生态特征。其生态化旅游开发的核心问题是旅游环境容量的确定与旅游环境的保护、民族特色与民族文化的弘扬以及注重旅游经济发展过程中旅游业的拉动效应及其依托性之间的关系处理等。     

Fire Severity,Water Repellency Characteristics and Hydrogeomorphological Changes Following the Christmas 2001 Sydney Forest Fires

Soil water repellency can enhance overland flow and erosion and may be altered by fire. The Christmas 2001 bushfires near Sydney allowed investigation of the relationship between fire severity, water repellency and hydrogeomorphological changes. For two sub-catchments with differences in fire severities in Nattai National Park, south-west of Sydney, this paper considers: (1) the links between fire severity based on SPOT image analysis and ground observation of fire severity and repellency; (2) the textural and organic/minerogenic characteristics of eroded sediment; and (3) erodibility, erosion and deposition of soils in both catchments. Ground surveys show that image analysis reflects well the degree of vegetation consumption by fire, but cannot adequately predict the degree of ground litter consumption, associated soil heating and repellency effects. Fire had varying effects on repellency, leaving it unchanged, destroying it or enhancing it, depending on the soil temperature reached. The main post-fire hydrogeomorphological changes have been widespread erosion and colluvial and alluvial deposition of topsoil in foot-slope locations and river systems, but only localised redistribution of the highly erodible, repellent sandy subsurface layer. The fire did not trigger major geomorphological change in the study area, but fires probably cause important topsoil and nutrient depletion and may also affect water quality.     

Transition and Diversity in Rural Housing Provision: The case of Narrogin,Western Australia

The purpose of this paper is to examine the changing dynamics of housing markets in an Australian rural community. With reference to the case of Narrogin, Western Australia, it argues that there is an increasing disjuncture between the social and demographic characteristics of rural residents and the modal form of housing in country towns, namely the detached family house. Factors contributing to this disjuncture include the ageing of the population, the loss of traditional blue-collar employment, sub-regional restructuring of service provision, retirement migration patterns, and growing acceptance of the particular housing needs of groups such as the aged, the disabled, young and indigenous people. While it is clear that there is currently something of a mismatch between the characteristics of the population and the housing stock in Narrogin, it is also evident that a combination of political, cultural and economic factors form a significant barrier to adjustment in the local housing market.     

Re-placing the Pilbara's mining unions

This paper examines the attempt by mining management in Western Australia's Pilbara to replace mining unions—quite literally—by removing them from the processes of representation and bargaining. It analyses the way in which those unions have tried to re-place themselves, in the senses of transforming themselves in those spaces in which they were already operating and reviving themselves where they were not. Where unionists have succeeded in these engagements, it has been by working at a range of geographical scales, using the ‘power of place’ in the Pilbara and reshaping traditional geographies of union organisation. It is suggested here that many of these emergent outcomes are the result of the embeddedness of geographically specific historical structures along with new intersections of nationally and locally scaled labour politics.
