美国外商制造业直接投资区域分异模式研究

本文以美国经济区为基本地域单元，以区位商和相关系数为主要研究指标，从一般投资区位和新建投资区位两方面研究了美国外商制造业直接投资区域分异模式。主要研究结论如下：外商制造业企业就业与美国制造业企业就业的区域分布很相似，但更倾向于集中在美国东南部；外商新建投资企业相对集中在新英格兰部分地区和东南部，得克萨斯和路易丝安那海岸地区，密苏里州和伊利诺伊州西部；外商新建企业倾向于分布在高人口密度区，但相关性没有美国本国新建企业强；外商新建投资企业与外商并购企业的分布略有不同。     

中国加入WTO对长江三角洲地区产业发展的影响

加入WTO对中国的经济运行环境和区域经济走势将带来深远的影响。长江三角洲地区是我国最有潜力和条件参与较高层次国际竞争的地区之一，但是该地区计划经济体制的影响较深，区域经济发展的问题和制约因素突出。因此，利用新的视角开展中国加入WTO对长江三角洲地区产业发展的影响的综合研究，对我国21世纪地区经济的发展和走向具有重要的指示意义。本文通过对长江三角洲地区产业发展的现状和主要问题作了探讨，并在此基础上，对中国加入WTO对长江三角洲地区产业的冲击力进行了评估和判断。本文认为，为应对中国加入WT0后所带来的冲击，抓住发展机遇，提高区域整体竞争力，长江三角洲地区各城市有必要形成共识，规范和统一地方政府行为，在充分发挥市场机制作用的条件下，对区域产业调控机制和模式作重新构思，以进行区域产业分工体系和区域产业分布格局跨省市、全区域的合作与协同调整。     

'In the shadow of hierarchy': meta-governance, policy reform and urban regeneration in the West Midlands

This paper explores the relationship between political hierarchy and the complex webs of political organization associated with urban governance. Deploying the concept of meta-governance and a study of urban policy reform in the West Midlands region of England, this paper claims that state and governmental hierarchies continue to have a crucial role in coordinating the activities of governance regimes in the UK. This paper concludes by considering the effects of hierarchical power on the systems of political participation and representation that are associated with urban governance.     

Regional characteristics of dust events in China

The regional characteristics of dust events in China has been mainly studied by using the data of dust storm, wind-blown sand and floating dust from 338 observation stations through China from 1954 to 2000. The results of this study are as follows: (1) In China, there are two high frequent areas of dust events, one is located in the area of Minfeng and Hotan in the South Xinjiang Basin, the other is situated in the area of Minqin and Jilantai in the Hexi Region. Furthermore, the spatial distributions of the various types of dust events are different. The dust storms mainly occur in the arid and semiarid areas covering the deserts and the areas undergoing desertification in northern China. Wind-blown sand and floating-dust not only occur in the areas where dust storms occur, but also extend to the neighboring areas. The range of wind-blown sand extends northeastward and southeastward, but floating-dust mainly extends southeastward to the low-latitude region such as the East China Plain and the area of the middle and lower reaches of the Yangtze River. Compared with wind-blown sand, the floating-dust seldom occurs in the high latitude areas such as North Xinjiang and Northeast China. (2) The affected areas of dust storms can be divided into seven sub-regions, that is, North Xinjiang Region, South Xinjiang Region, Hexi Region, Qaidam Basin Region, Hetao Region, Northeastern China Region and Qinghai-Xizang (Tibet) Region. The area of the most frequent occurrence of dust storms and floating-dust is in South Xinjiang Region, and of wind-blown sand in the Hexi Region. In general, the frequency of dust events in all the seven regions shows a decreasing tendency from 1954 to 2000, but there are certain differences between various dust events in different regions. The maximum interannual change and variance of dust events during this time happened in South Xinjiang Region and Hexi Region. The dust events generally occur most frequently in April in most parts of China. The spring occurred days of dust events occupied 60-70% of the whole year in Hetao Region and Northeastern China Region. However, in South Xinjiang Region and North Xinjiang Region, which was less affected by monsoon climate, dust events may occur at any time of the year, less than 50% of the events in this region occur during spring. In the remaining three regions 50-60% of the dust events occur in spring of a year.     

A FOOD GEOGRAPHY OF THE GREAT PLAINS

ABSTRACT. This article explores the regional identity of the Great Plains through its foodways using 744 responses from a mailed survey that asked participants to plan a representative menu for their locale. The strongest association is with beef—not surprising in an area known for cattle ranching. Other commonalities include potatoes, beans, and corn. Differentiation within the region is marked by preparation methods for beef as well as emphases on cornbread and peach cobbler in the south, rhubarb pie in the north, tortillas and sopapillas in the southwest, and pickles in two separate clusterings.     

油气化探中甲烷碳同位素应用、存在问题与对策研究

阐述了在地表油气化探实践当中甲烷碳同位素对地表土壤烃气成因判别的有效性，但有时也会遇到判断错误的情况。通过对应用实例的分析，指出因忽略了土壤中异常甲烷是一种混合成因甲烷，从而导致判断失误。为全面解决这一问题，提出了同时选送数量相当的背景土壤样品和异常样品进行甲烷同位素测定，然后通过教学方法计算出真实反映来源于油气藏中的甲烷的碳同位素值的对策方案。     

分形理论与灰色系统理论在南岭地区地质异常圈定和金矿资源预测中的应用

应用分形理论研究了南岭地区地质弄常及其圈定方法，结合灰色系统理论对该区的金矿资源进行了预测。通过研究，圈定了10个地质异常区和7个金成矿远景区，为南岭地区金矿地质勘查提供了依据。     

洁居纳卓组:西藏措勤地区的上新统岩石地层单位

分布于措勤县城一带的一套地层在1：100万日喀则幅区调中校划属上新统乌郁群，由下部火山岩和上部沉积岩组成。在1：25万措勘县幅区调中，根据获得的同位素年龄值已将下部火山岩地层划归古新统的典中组，而上部的沉积地层中含圆笠虫等有孔虫化石应属下白垩统。在这一地区还新发现一套陆相碎屑地层，根据其岩性组合、ESR年龄值及区域地层对比，本文将其新命名为上新统洁居纳卓组。
