How to Evaluate and Forecast Changes in Landscape Image: The Case of a Small River Valley in Poland

River valleys play a key role in functioning landscape systems on a regional and continental level. Their ecological and cultural functions have developed simultaneously for centuries, creating a unique composition. Cultural heritage has grown from natural heritage and has enriched it wonderfully. However, river valleys have become areas of particularly intense human pressure for approximately the last two centuries, but especially over the last half century; changes occurring in the landscape are more and more drastic. The analysis and evaluation of these changes can therefore be a good indicator and predictor of changes that occur in the environment of entire (regional and transregional) landscape systems. This paper presents the method and results of landscape studies based on the sequence: retrospection-diagnosis-variant prognosis. The aim of the present work was to attempt to answer questions concerning the future direction of the development landscape physiognomy of small river valleys.
