Abstract Jan KABRDA: Changing spatial pattern of land use in the Czech Republic and its driving forces The main objective of my.dissertation thesis is to analyse changes of spatial pattern of land use in the Czech Republic since the mid-19'n century. My secondary aim is to discuss advantages and limits of various methods that can be used for this research. The text is divided into two main sections. The first one includes an overyiew of literature on the given issue. The second one comments six attached articles that constitute the main body of the thesis, representing main results of my research. The first section of my thesis consists of three chapters. In the first one I discuss the term,,land use" itself; importance and practical applicability of its research; and theoretical approaches used throughout the world to explain patterns and changes of land use, and to create schemes for its;;search. Chapter Two includes an overyiew of methods and data sources used in land use research, especial|y of quantitativ" ón.,, in the whole world in general, and in Central Europe in particular. In the third chapter I summarize the main processes of land use changes - of current changes at global level, and of changes during last two centuries within the Central European context. The six attached articles represent main findings of my study. In five of them I applied a quantitative approach, analysing changes of regional pattern of land use with the help of the "Database of long-term land use changes in Czechia (1845 - 1948 - 1990 - 2000)". In the first article, I assessed changes ofdivision ofthe area of the Czech Republic into four ýpes of structure of agricultural land use (intensive, sharply and moderately intermediate, extensive). In the second and third article, I analysed regional differences of Land use changes in the Czech Republic in relation to proximiý to state border; and in re|ation to distribution of soil řypes, respectively' The fourth and fifth article examined land use changes in the Vysočina region based on qualitý of natural conditions (altitude, slope, official price of agricultural land); and on socio-economic exposedness (proximiý to main centres of settlement and to important traffic lines), respectively. The last article is different, based on a more qualitative approach. It analyses behaviour of farmers in two model regions (Český Brod and SněŽné) after the accession ofthe Czech Republic to the European Union. Main findings of my research can be summarised into three statements. Firstly, Iand use in the Czech Republic is spatially structured into a logical pattem corresponding to local conditions. Intensity of land use in^creases with improving natural conditions and growingó'ic activity / attractiveness. The influence of the so-called ..differential rent I'' is the main force forming this paťtern. Secondly, regional differences in land use grew during the examined period (1g45 processes of intensification in betterconditions and extensification in worse ones resulted into - 2000). The acreation of more compact typological land use regions. Causes of these trends lie at two levels. On the one hand, this differentiation, specialisation and concentration within a previously more homogenous system were results of a general modemisation of society, economy and technology - of "social metabolismi'. On the other hand, different,,driving forces" in partial time periods modified this general trend. During the years lg45 194g, free - market economy resulted into intensification in better conditions; extensification in worse conditions between the years 1948 - 1990 was caused by a socialist neglect of inaccessible plots, by a large-scale agricultural concentration, and by a massive mechanisation of farming; and continuing extensification-in worse conditions during last time period ( l 990 - 2000) was a result of restored market forceůnd of new state policies. Thirdly, I showed that the wide range of used natural and socio-economic characteristics influences land use pattem only to a certain extent. This fact is partly caused by an existence of other, mostly non-quantifiable factors, especially institutional; and partly by a plurality ofbehaviour ofindividual actors. Application of various quantitative methods revealed not only their advantages, but also constraints and |imits. I would like to stress two of them' Firstly, there exists a danger of a cónfusion of causality with correlation, and thus of an emergence of a "false dependency". This is given by significant and complex interconnections between individual natural and socio-economic variables influencing land use pattem. And, secondly, with quantitative methods we do not examine natural nor social processes themselves, but only their manifestations and reflections in landscape. Thus, these methods tend to be more descriptive than explaňatory, less contributing to our understanding ofreality. Therefore, I suggest enriching our research of land use changes in the Czech Republic by two approaches, which would lead us to a deeper understanding ofprocesses occurring ín landscape. Ťhe first one is social metabolism, which can serve to outline a general pattern of modernisation and óhune., of Czech agriculture and economy. The second one is behavioural approach, or qualitative methods to be" precise, that would explain behaviour of individual actors within this general frame. Key words: agriiulture - modernisation, Czech Republic, driving forces, land use, landscape quantitative methods, spatial paťtern. - macrostructure,
