Producer Services Research in Europe*

Four directions in producer services research in Europe are identified: the economic role of producer services for urban and regional development; the location of advanced producer services; the role of regional structures and innovative “milieu”; and local development and labor markets. Issues for future research include the role of producer services in the urban structuring and/or restructuring of world cities; the relation between producer services and interregional disparities; the integration of producer services into networks; and the impacts of the liberalization of producer services.     

Producer Services Research in the United Kingdom

This paper reviews recent research in the United Kingdom on producer services and suggests directions for further research. A recurrent theme in UK-based geographic research into producer services is the role of service activities, establishments, and trade in uneven development of the UK space economy, a role manifested in uneven provision and quality of services in peripheral regions. During the 1980s, overall growth in demand for producer services and the rapid rise in metropolitan London real estate costs reduced London's dominance, but these trends moderated by the end of the decade. In the absence of adequate government statistics, regular and standardized surveys are needed to compile a time series of service change in the United Kingdom. Directions for continued empirical research include the role of producer services in innovation and technology transfer, the implications of information technology for the location of employment in the sector, and the impacts of productivity increases on employment and wages.

ADVANCES IN APPLIED RESEARCH OF THE OUTGOING LONGWAVE RADIATION IN CHINA

The outgoing longwave radiation(OLR)observed by NOAA satellite series has widely applied in various researchfields since the 1980s in China.In this paper,advances of the applied research of OLR are described in the following re-spects:(1)Studies of the global ITCZ;(2)Climatology of the subtropical high over northern Pacific;(3)Studies of the tropical cyclone over West Pacific;(4)Characteristics of the intraseasonal variation(ISV)of tropical convective activities;(5)Divergence wind and large scale circulation over the tropics;(6)Studies of the air-sea interaction;(7)Estimation of precipitation over the Tibetan Plateau and the Yangtze River(Changjiang River)basin during therainy season;(8)Analyses of regional climates of China;(9)Studies of prediction of the severe and disastrous weather and climate;(10)Atlas of OLR.The distinctive features of these advances are reviewed and the focal points of the OLR applied research in futureare also suggested.     

内蒙古呼盟地区地震活动的基本特征

通过对内蒙古呼盟地区地震活动的研究,认为呼盟地区震中分布较稳定;存在20年左右地震活动周期;震源机制两节面分布相对比较稳定,P、T轴近水平向;地震破裂是以水平滑动为主。将来呼盟地区的地震活动主体地区为博克图、满洲里一带,震级为5级左右。     

中国地区工业结构变化与区际增长和分工

1979以来,中国地区工业结构发生了重要的变化。本文分析了这一变动的特征及其对区际增长和分工的作用,得出以下结论:（1）绝大多数省市区工业结构变化高于国家水平,但由于各地人均收入、区位性以及结构性差异,这种变动具有明显地理分异:南大北小,东西部大中部小。（2）各地工业结构变动普遍表现为重加工业地位上升,采掘工业地位下降,且多数省市区原材料工业和轻工业地位下降,高加工度化和重加工业化十分显著。（3）广东、江苏、福建、河北、安徽、湖南、陕西、浙江、甘肃、云南、四川等省区结构调整有利经济增长,其它省市区结构调整相对不利经济增长。（4）资源型地区数量减少,加工型地区较大幅度地增加,基本形成沿海沿江地区和陕西省以加工业为相对专业化部门,其它广大地区以采掘、原材料为相对专业化部门的区际分工格局。     

Sectoral Composition and Spatial Distribution of Department of Defense Services Procurement*

The purpose of this research is to analyze the composition and distribution of Department of Defense (DOD) services procurement. The results indicate producer services comprise 53% of DOD services outlays. Defense expenditures for services are particularly important in the Washington, D.C., region and in states that either produce weapons or house defense-related R&D facilities. Defense expenditures are providing impetus to service sector growth in Virginia and, simultaneously, are providing the initial stimulus for development of producer services in states such as New Mexico.     

有限元法在中国南海及邻域区域稳定性研究中的应用

本文运用有限元法对南海及邻域现代构造应力场进行了初步的计算,结果表明:应力差(△a)的数值呈现有规律的分布,根据△a值的大小可以把本区划分为四个活动区:它们分别是烈活动区(△a>500bar)、强活动区(250bar<△a<500bar)、中活动区(12Sbar<△a<250bar)、弱活动区(△a<125bar)。其中南海北部及华南沿海地区属中活动区,这种环境对工程建设较为有利。     

红层砾石组分是区域地层对比的良好标志──以赣西北中─晚第三纪的砂砾岩为例

根据赣西北中─晚第三纪陆相紫红色砂砾岩岩性横向上不太稳定的特点，提出砾石成分的来源和成因特征可作为区域地层对比的标志，因为砾石成分作为风化和搬运的最终产物，它与基底母岩区是密不可分，又相互影响。     

闽南区域地壳稳定性分区及其特征

通过一系列区域地壳稳定性背景资料的分析，以地壳结构、深断裂、活动断裂、第四纪升降速率、大地热流值、布格异常梯度、地壳应变能量、地震最大震级、基本烈度等综合指标，将闽南区域的地壳稳定性，自西而东划分为稳定区、基本稳定区和次稳定区。
