摘要:The analysis of the dolines density on the North Velebit and Senjsko Bilo is shown. On 947 km2 has been registrated 18 059 dolines. One of the basic characteristic is the regular ranges of dolines, principally in direction NW-SE, and the regular change of the zones of bigger and smaller density. This indicate that the influence of the fault zones is essencial. The disposition of the ranges of dolines density has an exceptional morphostructural importance. There are three main fault zones: 1. Melnice-Kuterevo NW-SE, 2. Krasno-Lipovo polje WNW-ESE, 3. Bakovac fault zone E-W. The highest intensity of the dolines density is related to a wider area of convergention of three mentioned fault zones i.e. to the SE edge of Senjsko bilo, weider area of Lipovo polje and Bakovac.
