随着信息化建设的深入发展,计算机及网络应用范围不断拓展,应用系统的规模不断扩大,所面临的一个共同问题是如何在原有的建设基础上,进行信息资源的整合,实现信息资源共享。本文以福建省数字林业政务信息共享平台构建为例,在尽可能利用和保护原有投资存量的前提下,针对分布式异构环境中的林业数据和业务应用系统的信息共享要求,提出了基于.NET平台,运用先进的XML&Web Services/MS BizTalk Server2004核心技术的信息交换和共享的整体解决方案及其实现方法。  相似文献   

数字区域应用基础设施研究     

吴升  王钦敏  涂平  励惠国 《地球信息科学学报》2006,8(4):19-24

针对当前数字区域工程建设普遍存在的一些问题,提出“数字区域”应用基础设施的概念,对其研究背景、参考模型和面向信息共享的公共应用服务平台进行了论述。数字区域应用基础设施是在区域网络基础设施和数据基础设施上层的基础设施,它为电子政务、电子商务、数字城市等各种数字区域信息化应用工程提供基础性的应用服务支撑,由专业信息服务机构、管理办法、标准规范、关键技术和公共应用服务平台构成。信息服务机构是数字区域应用基础设施的主体,是有效联系信息需求方和信息拥有方的桥梁;公共应用服务平台是数字区域应用基础设施的核心,为区域信息共享和交换提供了统一的构架和解决方案。其中,元数据管理和目录服务平台为信息的发布和查询提供了“一站式”入口;信息共享与协作服务平台实现了分布式数据库的信息共享和交换;地理空间信息网络服务平台实现了地理空间信息的集中式共享。最后,总结了“数字福建”应用基础设施建设的成果,对“十一五”“数字福建”工程的需求和发展作了展望。  相似文献

The article discusses the importance of services as agents of internationalisation. Services are seen as dynamic agents of change, and services and commodities are considered composite in production processes. Modes of entering the global scene such as trade in services, foreign direct investment, forming of alliances, franchising and intrafirm trade are focused on, and limits to globalisation are highlighted. Some services, particularly advanced business services, more easily fall prey to institutional and cultural constraints than others. Empirically, Norway is analysed as an arena of international services against the background of its historical tradition particularly in shipping and affiliated activities. Recently, however, manufacturing has gained in importance, mainly in exports and to a lesser extent in imports, due to the petroleum economy. This appears to indicate that export of services has lost momentum over time. The development profile in shipping is highly negative. The negative picture changes somewhat when not only the trade balance, but also investment abroad is considered. In this respect, services have grown in relative importance, notably in the financial sector and in telecommunications. When juxtaposing outgoing and incoming investments, petroleum-related services have gained an increased export and investment surplus in recent years, from a balance in the mid-1990s.  相似文献   

中国出境旅游与国际服务贸易关系分析     

章锦河  刘珍珍  陈静  周晶  李曼 《地理科学》2012,(10):1161-1167

出境旅游是国际服务贸易的重要组成部分,是世界经济全球化的响应。出境旅游与国际服务贸易关系分析是制定出境旅游政策的基础之一。根据1985~2011年中国出境旅游和国际服务贸易时间序列的相关数据,采用计量经济学分析方法,系统探讨了出境旅游与国际服务贸易的关系。得出结论:①出境旅游与国际服务贸易之间存在正相关关系;②出境旅游与国际服务贸易存在长期稳定的动态均衡关系;③出境旅游与国际服务贸易存在短期波动回归长期均衡关系;④出境旅游是国际服务贸易出口的Granger原因,但不是国际服务贸易进口的Granger原因,国际服务贸易进出口均是出境旅游的Granger原因。  相似文献   

不同土地利用方式下的七里海湿地临界评价研究   总被引：2，自引：0，他引：2  

蔡为民  杨世媛  汪苏燕  周楠 《地理科学》2012,(4):499-505

在"湿地临界"概念的基础上,定性分析了湿地利用与保护的平衡状态,探讨了不同利用方式下的湿地临界的研究步骤,并从基于耕地和河蟹养殖地两种土地利用方式入手,对七里海湿地临界进行了评价。研究表明,通过建立湿地临界模型,从经济效益评价和生态效益的评估入手,对湿地资源利用与保护进行临界分析,可以较好的反映湿地利用的临界状态;采用该方法,七里海湿地耕地利用的年净收益为9 5941.42元/hm2,净损耗为18 072.75元/hm2,临界效益(△B)值为77 868.67元/hm2;养殖河蟹的年净效益为21 622.68元/hm2,净损耗为2 0274元/hm2,△B值为1 348.68元/hm2,说明在目前的社会经济发展水平下,耕地和养殖河蟹两种利用方式尚未超出开发利用的临界准则,七里海湿地仍然具有开发潜力。  相似文献   

Monitoring directions and rates of change in trees outside forests through multitemporal analysis of map sequences   总被引：1，自引：0，他引：1  

Tobias Plieninger 《Applied geography (Sevenoaks, England)》2012,32(2):566-576

This study explores the potential of historical maps to detect, measure and monitor changes of trees outside forests. The main goal is to assess local-level changes of scattered trees and orchards and their land-use determinants in two areas in Southern Germany between 1901/1905 and 2009. Firstly, overall landscape changes are recorded. Secondly, the spatial-temporal trajectories of scattered trees and their land-use determinants are identified. Thirdly, changes in quantity and fragmentation patterns of traditional orchards are analyzed in their relationship to overall land-cover change. The results confirm major losses in scattered trees, mainly due to urbanization, agricultural intensification, and land abandonment. They further reveal that, while orchards have persisted in total area, they have undergone critical changes toward a simplified landscape structure and loss of the traditional land-use mosaic, which is a characterizing feature of high nature value landscapes. Multi-temporal assessment showed that most trends have been continuous and did not change directions over time, but rather accelerated during periods of rapid change (most dramatically in the 1950-1990 period). The case of orchards and scattered trees illustrates a major problem of cultural landscapes in Europe: Semi-natural landscape features of high nature value are threatened by both intensification and abandonment of land uses. This makes their conservation a potentially costly enterprise, as both opportunity costs for lost alternative land uses and for conservation management costs arise.  相似文献   

An exploratory spatial analysis of western medical services in Republican Beijing     

Peiyao ZhangAuthor VitaeDavid W. WongAuthor Vitae  Billy K.L. SoAuthor VitaeHui LinAuthor Vitae 《Applied geography (Sevenoaks, England)》2012,32(2):556-565

In this paper, we reconstructed the spatial organization of Western medical services in Beijing city during the Republican period using a recently completed Republican Beijing GIS dataset. The primary objective is to explore the utility of spatial analytical methods, such as hotspot analysis and geographically weighted regression (GWR), in studying the spatial patterns of Western medical services. Our study is successful in depicting the spatial structure of Western medical services in the city. In addition, our analysis offers a preliminary but holistic view of the spatial relationships between Western medical services in the city and traditional Chinese medicine, population distribution, temple locations and industry-commerce patterns.  相似文献
