中原经济区城市体系空间组织

新型城镇化是引领中原经济区“三化”协调发展的重要切入点,而城市体系空间组织又是支撑新型城镇化的主要载体。依据空间组织的基本理论,采用多种空间分析手段,分析了中原经济区城市体系的空间组织路径,结论如下：① 通过规模实力、综合实力评价模型计算中原经济区30个省辖市的空间组织等级,结合空间组织的均衡原则,确定以郑州为核心城市,洛阳、邯郸、信阳和商丘为区域中心城市,晋城、安阳、南阳、淮北为区域性次中心城市的等级体系;② 应用分形理论、圈层分析、缓冲区分析、城市相互作用模型等方法分析发现,中原经济区具备以郑州为核心的圈层式、轴带状、核心板块网络化、组团分区的组织基础;③ 结合空间组织的等级层次和现实基础,提出中原经济区空间组织的“中心带动、圈层推动、轴带组织、核心板块网络化、组团分片”的模式选择与路径取向。

国际组织选择和聘用咨询顾问程序及其指南的比较研究

本文比较研究了国际组织和地区性开发机构,如世界银行、亚洲开发银行、欧盟等在国际工程中选择咨询顾问所采用的一般程序;并在此基础上对这些国际组织选择咨询机构的作业文件——选择咨询服务的指南进行了比较研究。这种比较研究可以使我们深入地了解国际组织聘用和选择咨询顾问的运作步骤,及其细微的区别,以正确的更具针对性的策略参与国际项目竞争。同时随着我国招投标法的即将实施,本文也为如何参照国际惯例制定相关领域的具体政策和操作程序提出了有价值的建议。     

Organizing coordination for an ecosystem approach to marine research and management advice: The case of ICES

This study examines the reorganization of formal coordination structures of a unique international public organization involved in marine governance in Europe, namely the structural reorganizations of the International Council for the Exploration of the Sea (ICES) between 1999 and 2009. The findings indicate that the reorganizations of ICES’ formal coordination structures were not driven primarily for reasons of efficiency, by clear and consistent goals, and by clear means-ends considerations for organizational design as proposed by rational perspectives in organization theory. Instead, the formal coordination structures have also been adapted to live up to changing expectations in the institutional environment, to modern management concepts in marine governance such as the Ecosystem Approach to Management (EAM), and to ensure the legitimacy of the organization. However, it is also found that institutional explanations alone are insufficient to comprehensively understand why the formal organizational structures of ICES were reorganized. Instrumental and cultural perspectives in organization theory as well as resource-dependence theory additionally add to understand how ICES responded to external demands and why organizational structures have been changed.     

专题地图设计辅助案例库建设的若干问题

地图制图案例是地图制图经验与知识组织与管理的基本单元。专题地图设计辅助案例库建设旨在构建一个独立于制图人员的地图制图经验与知识持续积累、有效融合与便捷再应用的系统与方法。文章立足于地图生产的现实需求,从工程化视角介绍了地图设计辅助案例库建设的研究内容与基本思路,重点对专题制图案例模板的内容设计进行了论述。地图制图案例库建设与应用为实践中地图设计水平与地图生产效率的持续提高提供了有效的支持。

空间编码QuaPA方法的改进与实验

空间编码是GIS与全球空间数据组织与共享的重要基础。针对QuaPA编码方法进行三维与全球空间编码时存在数据冗余和象限二义性问题,采用双Morton编码和象限标识后置方式进行改进,提出QuaPA 方法。介绍QuaPA 编码步骤及其反演原理,并以中国及邻区地表及地下10 km2、0 km以浅的三维球壳空间网格划分为例,分别进行了球壳网格的QuaPA和QuaPA 编码实验。实验表明,QuaPA 编码解决了象限二义性问题,缩短了编码长度,节省了存储空间。
