Tywa river valley, located in western part of Szczecińska Plain, flows through moraine areas of Myśiborskie Lakeland and Wełtyń Plain. River valley has high slope values and denivelations, so many hydrotechnical objects were located here in the past. There were no intensive other river regulations and melioration, so valley has still high biocenotical value. Analysis of landuse changes in riverine valley are presented in this paper, as well as analysis of changes directions and patch statistics. Archival topographical maps from 19th and 20th c. were used for preparation of landuse digital maps.
