■人为的景观变化是塑造我们环境的重要驱动力。历史景观分析有助于监测和理解这些变化过程。这种分析通常集中在特定的空间尺度和单一的研究方法上,因此仅涵盖景观变化的有限方面。
■这里,我们的目标是评估将历史航空图像分析与当地利益相关者访谈相结合,以使用标准化的制图和访谈方法进行景观变化研究的潜力。
■我们比较了欧洲的六个农业景观,并使用历史航拍图像绘制了土地覆盖图(从1930年到1980年,取决于数据可用性,直到最近几年)具有基于对象的图像分析和随机森林分类。对于景观变化的本地观点,我们对(几乎)退休的农民进行了口述历史访谈(OHI)。比较两种方法记录的景观变化,可以深入了解结合这两种方法的优势。
■基于对象的分析能够识别高分辨率的土地覆盖动态,规模扩大和农田/草地扩张是整个欧洲景观中最常见的趋势。在OHI中确定的感知景观变化包括农场管理的变化,景观结构,和基础设施。农民还报告了与景观变化相关的驾驶员和个人价值观。结合两种历史景观分析工具,对土地覆盖的变化进行了定性和定量的理解,土地利用,和土地管理。
■将实际土地覆盖变化与当地农民观点进行比较是全面了解景观变化的关键。两种方法有不同的组合方式,导致科学和政策制定的不同场所。

UNASSIGNED: Anthropogenic landscape change is an important driver shaping our environment. Historical landscape analysis contributes to the monitoring and understanding of these change processes. Such analyses are often focused on specific spatial scales and single research methods, thus covering only limited aspects of landscape change.
UNASSIGNED: Here, we aim to assess the potential of combining the analysis of historical aerial imagery and local stakeholder interviews for landscape change studies using a standardized mapping and interviewing approach.
UNASSIGNED: We compared six agricultural landscapes across Europe and mapped land-cover using historical aerial imagery (starting between 1930 and 1980, depending on data availability, until recent years) with an object-based image analysis and random forest classification. For local perspectives of landscape change, we conducted oral history interviews (OHIs) with (almost) retired farmers. Comparing recorded landscape changes from both approaches provided insight into advantages of combining these two methods.
UNASSIGNED: Object-based analysis enabled the identification of high-resolution land-cover dynamics, with scale enlargement and cropland/grassland expansion being the most commonly recurring trends across European landscapes. Perceived landscape changes identified in the OHIs included changes in farm management, landscape structure, and infrastructure. Farmers also reported drivers and personal values associated with landscape change. Combining the two historical landscape analysis tools resulted in a qualitative and quantitative understanding of changes in land-cover, land use, and land management.
UNASSIGNED: Comparing physical land-cover change with local farmer perspectives is key to a comprehensive understanding of landscape change. There are different ways the two methods can be combined, leading to different venues for science and policy making.
