We introduce a simple method for estimating the changes of nitrate concentrations in surface waters regarding the land use modification. Stream and drainage water nitrate concentrations in prevailingly agricultural catchments of three different scales located in the Crystalline complex of the Czech massif, Czech Republic, were included in this study. Water quality samples were collected through the years 1992-2006 at monthly and bi-monthly intervals.

This article deals with the theoretical issues of land resources evaluation, land fund structure, problems and directions of rational use of land resources in the Republic of Kazakhstan.
