Quantitative and Qualitative Approaches of Delineation in Detailed Mapping of Vineyard Landscape. Case Study: Vicinity of Pezinok (Slovakia)

The main goal of this paper is the application of qualitative and quantitative free available data for geographical delineation based on reconnaissance research in vineyard landscape. The results of delineation are useful in agricultural management or environmental planning. Our delineation may serve as the basic information on site conditions of vineyards near Pezinok (Slovakia), with historical use from the beginning of 13^th century. We have studied the actual land cover and classified physiotopes of the study area into a set of relatively homogenous and coherent landscape units. The landscape units defined in this work consist of homogenous physiotopes in terms of their structural and functional characteristics, which have been shaped by natural factors (land-forms, soil type and subtype, geological base, elevation, slope, aspect, solar radiation and normal different vegetation index (NDVI)). The characteristics were used to define 23 landscape units in qualitative delineation (based on both qualitative and quantitative data). Only quantitative characteristics – elevation, aspect, slope, solar radiation and NDVI, were used in a K-means cluster analysis to define the 17 landscape units. The number of landscape units was computed by WB-index, and standardisation of data was computed by factor analysis. The whole classification process was statistically significant. The strength of the grouping procedure was tested by using Discriminant Analysis, which found that 92.70% of objects in qualitative and 98.50% of objects in quantitative delineation were correctly classified.
