ABSTRACT

This paper presents a new geographical analytical model for studies on agricultural landscape change. The model builds on the idea presented by Torsten Hägerstrand that neighbourhood configurations act as filters in change processes. The proposed approach operationalizes this idea of filtering into a geographical interpretation model that combines three different strands of research: ontologies of land use in geographical information science; local spatial contextual analysis of remote sensing data; and agency- and actor-sensitive functional time-space analysis of farming. This approach includes the use of satellite images and makes it possible to infer land-use changes as reactions to long-term policy changes, thus demonstrating how landscape configuration and land use are changing. The model is assessed by applying it to a case study in western Östergötland in central Sweden.

摘要

本文为农业景观变化研究提供了一种新的地理分析模型。。该模型基于TorstenHägerstrand提出的想法，即邻域配置在变更过程中充当过滤器。所提出的方法将这种过滤概念转化为地理解释模型，该模型结合了三个不同的研究领域：地理信息科学中的土地利用本体论；遥感数据的局部空间语境分析；以及对代理和演员敏感的农业功能时空分析。这种方法包括使用卫星图像，并且可以推断出土地利用变化是对长期政策变化的反应，从而证明了景观配置和土地利用的变化。该模型已通过将其应用于瑞典中部东部Östergötland的案例研究进行了评估。
