论地理边界的科学属性与表达

地理边界的科学界定体现着对地理对象空间分异规律科学抽象与系统分析的认知水平,是地理学的基础科学问题。本文从地球系统科学的视角,首先阐述了地理边界的基本概念、科学内涵与基本属性等核心概念问题,基于科学性、系统性的基本原则,以内在机理、外在表现以及科学属性等视角为核心依据,对地理边界进行了系统分类。论文分析了地理边界的数学内涵与表达方法,比较了传统地理边界划分法和现代地理边界定量划分方法的特点与差异性,提出了集定性、定量、定位为一体的“地理边界模型”的研究架构。该研究盼在地理边界这个地理学基础理论问题上进行概念辨析与方法分析,丰富地理信息科学的理论与方法。

Scientific attributes and expression methods of geographical boundary

The scientific delineation of geographical boundary, which is the basic scientific issue of geography, reflects the cognitive level of the spatial variation of geographic objects from scientific abstraction and systematic analysis. From the perspective of earth system science, this paper first explicates the core issues of the basic concepts, scientific content and basic properties of geographical boundary. Based on the principles of scientificity and systematicness, the paper classifies geographical boundaries systematically according to the intrinsic mechanisms, extrinsic appearance and scientific attributes of geographical systems. This paper focuses on the analysis of the mathematical connotation and expression of geographical boundaries. In addition, it compares the characteristics and differences of traditional and modern methods for geographical boundary delineation. Finally, we construct the research framework of "geographical boundary model", which integrates the characteristics of qualitative, quantitative and positioning methods of geographical boundary. The research is expected to enrich the theory and method in geographical information science with the analysis of concept and method of geographical boundaries.
