Abstract
This paper deals with the spatial density of dolines in the Croatian territory covered by karst. The purpose of this paper is to calculate the spatial density of dolines and show a correlation between calculated doline density values and certain geomorphological and geological factors of their origin and development. Therefore, it has been necessary to calculate the spatial density of dolines applying unique GIS methods of data collection and analysis to the entire study area. Doline density per unit area has been calculated based on the mapped doline bottom. 1:25,000 scale digital cartographic models have been used to determine the doline bottom. The given data have been used to calculate the spatial density of dolines applying a simple kernel method to an area of one square kilometre. The analysis of spatial differences in doline density has revealed that certain connections exist between doline development and relief morphometric parameters as well as lithological and structural terrain features.
