Abstract

Many scenic assessments have been carried out on a subjective base. A novel technique addressed scenic evaluation, through application of fuzzy logic methodologies to values obtained from a checklist that itemized 26 physical and human parameters. These parameters, obtained by consultation with coastal experts and users, were rated on a five-point attribute scale, covering presence/absence or poor quality (1), to excellent/outstanding (5). These attributes, subjected to fuzzy logic analyses producing matrices/weigbtings, which reflected parameter importance and culminated in weighted averages and membership degree figures, gave an overall result for scenic assessment over attributes. These values enabled calculation of an Evaluation Index (D), which categorized all sites and statistically best-described attribute values in terms of weighted areas. High weighted averages for attributes 4 (excellent) & 5 (outstanding) reflected high scenic quality. For Croatia, 33 sites were investigated and areas found to group into five distinct categories: CLASS 1: Extremely attractive natural sites with a very high landscape values and a D value > 0.85. CLASS 2: Attractive natural sites with high landscape values and a D value between 0.65 and 0.85. CLASS 3: Mainly natural sites with little outstanding landscape features and a D value between 0.4 and 0.65. CLASS 4: Mainly unattractive urban sites, with a low landscape value and a D value between 0 and 0.4. CLASS 5: Very unattractive urban sites, with intensive development, a low landscape value and a D value below zero.
