区域可持续发展评价指标体系的构建思路

区域可持续发展的哲学理念自提出以来,立即受到全世界范围的广泛响应。但各个团体对区域可持续发展的具体理解又各自不同。本文论述了区域可持续发展评价指标体系构建的必要性及其构建的基本原则。在此基础上,对区域可持续发展评价指标体系构建的大致框架进行了设计,并就指标体系构建中应注意的一系列问题及指标选取中定性与定量的关系问题作了扼要的论述。     

基于偏离-份额分析法的江苏海洋产业结构分析

一个地区的经济增速很大程度上取决于当地的产业结构,同理海洋产业的增值原动力也来源于海洋支柱产业。支柱产业是一个区域的发展根本,对相应产业进行结构调整,使其更加合理,才能保持海洋经济的持续增长。因此,文章的研究目的在于分析江苏省近几年的四大海洋支柱产业结构,在此基础上根据江苏省独特的海洋经济状况,为江苏的海洋支柱产业发展提供一些建议,将滨海旅游业、海洋船舶业、海洋交通业、海洋渔业这4个支柱产业继续深挖潜力,提升竞争力,让良好的产业基础发挥优势。

山东省海洋产业结构水平综合评价研究

文章从山东省海洋产业结构的静态和动态基本情况入手,分别运用偏离份额分析法和相似判别法对山东省海洋产业结构的合理化和高度化水平进行评测;通过建立区域海洋产业结构水平综合评价指标体系,运用基于熵权法的模糊综合评价方法,综合评价山东省海洋产业结构水平。结果表明,山东省海洋产业结构较为稳定,合理化和高级化水平有待提高,综合水平优势不显著,应加快海洋产业结构的优化升级。     

地球系统科学与地球信息科学

地球系统科学不是脱离社会而存在的一门科学,不是纯自然的科学。研究地球系统科学应该始终如一贯穿"顶天立地"的统一性原则:"顶天"即研究全球变化,"立地"则面向区域持续发展。区域模型和宏观调控信息系统依次作为两个中间层次,有机地将全球变化研究和区域持续发展联系起来,构成地球系统科学体系;时代进步和社会发展要求:地球系统科学研究要运用空间信息技术工具和手段,以服务区域持续发展为最终目标.区域持续发展要依靠宏观调控,宏观调控则依靠信息。地理信息系统作为空间信息技术组成部分,直接参与实现区域持续发展,成为地球系统科学的一个重要支柱。     

Fracture and in-situ stress patterns and impact on performance in the Khuff structural prospects,eastern offshore Saudi Arabia

We characterized natural fractures and in-situ stresses for exploration and prospect evaluation in nine periclinal structural traps, in the Eastern Province of Saudi Arabia, where several major gas discoveries were made in the deeply buried, Permian–Triassic Khuff Formation. Borehole image logs, oriented cores, seismic, gravity-magnetic data, and dynamic observations were used in the study. Two fracture systems were identified: a younger, major system, which enhances reservoir permeability and an older, minor, fully mineralized system. The older system consists of subordinate northerly striking extensional mesofractures, including joints and faults, which are fully mineralized by anhydrite and calcite. This mineralization occurred during an early diagenetic-phase. This system acted as paleo-fluid conduits, facilitating the occlusion of matrix porosity and deteriorating the reservoir quality in the immediate vicinity of the fractures. The younger system is regionally dominant, and includes mesofractures with persistent strike ranging from NE–SW to ESE–WNW irrespective of local structure. These younger fractures are nearly parallel to the present day maximum horizontal in-situ stress and perpendicular to the minimum horizontal in-situ stress, which are dominated by the Zagros plate tectonics. The development of this system commenced during the convergence of the Arabian and Eurasian plates (Late Cretaceous to Cenozoic) and culminated during the continental collision. The fractures are predominantly extension joints and hybrid (extensional-shear) fractures, and were facilitated by increases in pore pressure due to the oil placement and the subsequent cracking of this oil into gas. Hydrocarbon migration into the Khuff reservoirs was crucial in slowing down diagenesis and preserving both fracture apertures and matrix porosity. Therefore, most of the fractures in this system tend to be partly mineralized, mainly by carbonates, and/or coated with hydrocarbons. These fractures show channel-type apertures that enhance permeability and productivity of the Khuff by up to two fold. The channel apertures can endure operational changes in reservoir pressure with little or no reduction of their permeability. Critically stressed open fractures have no major role. Geomechanical analyses show that they are estimated to occur under the upper limits of differential stresses, within the margin of error of stress estimates. The static and dynamic observations show the permeability and productivity enhancement follows mechanical layering patterns. Production and pressure profiles in individual wells indicate lack of vertical communication (seal breach) across the different reservoir units. Similar pre-production pressure and hydrocarbons across the Khuff reservoir units is the result of normalization over geological time. Hydrocarbon migration across the anhydrite seals happened via episodic paleoseismic pumping along faults with no sufficient vertical offset to permanently breach the reservoir seals.     

The Irish marine economy and regional development

The economic impact of the marine economy is poorly understood at both national and regional levels in Ireland. A recent paper estimated the national level economic value of the sector for Ireland. This paper presents a follow up analysis of the Irish marine sector at the regional level for 2007. The paper examines the impact of the marine sector in addressing regional disparities in Ireland, and the key marine sectors that drive regional economic performance within the marine sector. The analysis finds that in absolute values Dublin and the South West provide the highest levels of marine GVA; however, as a percentage of regional GVA, the marine sector is more important in the West and South West region. In terms of employment, the West and South-West provide the highest levels of marine employment, and this relationship is maintained when one examines marine employment as a percentage of regional employment. Finally, productivity rates for the sector were highest in the Dublin region. However, productivity in the marine-based sector was higher than the overall regional rate for five of the eight Irish regions.
