Monitoring landscape changes, especially conservation sites, is essential to sustain the environment and landscape diversity (towNseNd et al. 2009). By now, it is evident that the thematic resolution of classified data sets affects the results of land use/land cover and landscapestructure analysis. However, uncertainty regarding the ambiguity of classification schemes and the impact of generalizations have not been sufficiently addressed until now (lechNer et al. 2012). This study applies digital vector data of biotope types and land use mapping to gain further systematic insights into these questions. The data sets are available area-wide for 2 years (1993 and 2006), using the example of the Rhoen biosphere reserve situated in central Germany. The objectives of the study are 1) to consider the effect of thematic resolution on the magnitude of land use and land cover changes, 2) to assess the impact of thematic resolution on the analysis of landscape patterns, and 3) to investigate which thematic resolution is most suitable to detect differences between the biosphere reserve zones regarding the temporal development of the landscape structure. To achieve the objectives, the initial data are reclassified into data sets, encompassing 9, 27, 59, and 204 classes. Results indicate a considerable effect on the magnitude of detectable landscape changes at low or very high thematic resolutions and a high sensitivity of landscape metrics. However, landscape metric values show not only quantitative (discrepancies of values) but also qualitative (divergences of direction of change) impacts.

保护监测中的专题决议——以生物圈保护区为例评估分类细节对景观分析的影响

监测景观变化，尤其是保护区，对于维持环境和景观多样性至关重要（townNseNd 等人，2009 年）。到目前为止，很明显分类数据集的主题分辨率会影响土地利用/土地覆盖和景观结构分析的结果。然而，直到现在，关于分类方案的模糊性和概括的影响的不确定性还没有得到充分解决（lechNer 等人，2012 年）。本研究应用生物群落类型和土地利用地图的数字矢量数据，以进一步系统地了解这些问题。以位于德国中部的 Rhoen 生物圈保护区为例，这些数据集可在 2 年（1993 年和 2006 年）的区域范围内使用。该研究的目标是 1) 考虑专题分辨率对土地利用和土地覆盖变化幅度的影响，2) 评估专题分辨率对景观模式分析的影响，以及 3) 调查哪个专题分辨率最适合检测生物圈保护区之间关于景观结构时间发展的差异。为了实现目标，初始数据被重新分类为数据集，包括 9、27、59 和 204 类。结果表明，在低或非常高的主题分辨率和景观指标的高灵敏度下，对可检测景观变化的幅度有相当大的影响。然而，景观度量值不仅显示数量（值的差异）而且还显示质量（变化方向的分歧）影响。
