摘要
We have developed a new hierarchical European Landscape Classification that call be used as a framework for. e g, indicator reporting and environmental sampling. Landscapes are ecological Meaningful units where many processes and components interact. And as such, landscapes themselves have resulted from long-term interactions of natural abiotic. biotic and anthropogenic processes A good understanding of landscapes is essential for its assessment, protection, management and planning An internationally consistent approach is therefore obligatory and the production of landscape classifications and associated maps is all important tool in this context Although intuitive maps are available there are no consistent quantitative maps of European landscapes. In this paper, landscapes are regarded as forming recognizable parts of the earth's surface and as showing a characteristic ordering of elements. The complex nature of the underlying scientific concepts, which sometimes overlap and conflict, requires an objective and consistent methodology, as described in the present paper. As there are many regional differences in landscape properties, it is crucial to strike the right balance between reducing the inherent complexity and maintaining all adequate level of detail Against this background,a European Landscape Map (LANMAP) has been produced, making use of available segmentation and classification techniques Oil high-resolution spatial data sets. LANMAP is a landscape classification of Pan-Europe with four hierarchical levels: using digital data oil climate, altitude. parent material and land use as determinant factors, and has 350 landscape types at the most detailed level At this level there are 14,000 mapping units with a minimum mapping unit of 11 km(2). Thus far, LANMAP is limited to a biophysical approach. since there is a lack of consistent and European-wide data oil cultural-historical factors. This paper describes the conceptual background of LANMAP.
