The following conclusions have been reached as a result of the study: 1. The differentiation of types of geocomplex boundaries reflects the landscape diversity of the researched area. Even though rather small, three different groups of boundaries were identified in the area, corresponding to three different landscape types. 2. Delimiting geocomplex boundaries should be preceded by a detailed analysis of the characteristics of the researched area. The dissimilarity of the valley landscape suggests that a separate method for distinguishing geocomplexes should be elaborated for this landscape type; it would take into account small differentiation of the area with regard to relief and a significant influence of water conditions on the functioning of landscape. 3. As a rule, the analysed features (density, tortuosity, contrast, unequivocality) do not manifest any interrelationships. The only observable relationship is the fact that the strongly contrasting boundaries are also unequivocal. 4. The highest density of boundaries was found in the loess landscape, characterised by most diverse relief. 5. In all the analysed landscape types, boundaries are characterised by a similar degree of tortuosity. It was found out that the highest tortuosity of boundaries characterised the loess landscape. In the author's opinion, this is due to a marked diversity of relief in the loess landscape. 6. In the three types, the most frequent type of boundaries in terms of contrast are low-contrast boundaries. The highest share of high-contrast boundaries characterises the valley landscape; they are boundaries separating water bodies from land). 7. The highest degree of unequivocality characterises the boundaries of geocomplexes in the loess landscape, which is due to the occurrence of many diverse, distinct landforms.

The presented article is focused on the problem of landscape boundaries function. It is concentrated on investigation methods. The research was realized in Wigierski National Park (north-east Poland) in 1:25 000 scale. The stability and the porosity of selected landscape boundaries were evaluated using point scales. The proposed method allowed to describe functional diversity analyzed boundaries. It was stated, that the way of landscape boundary functioning is connected to its genesis. The advantage of the proposed method is that it allows to coverage relatively big area in a short time. Obtained results can be used as a base for more detailed research. They can also be utilized at various stages of spatial planning process.
The aim of the paper is the critical analysis of the current state of development of sailing facilities - marinas and berthing sites on the shores of the Great Masurian Lakes (Poland). The research is both of quantitative and qualitative character. Facilities and their capacity were counted and mapped. Field observations focused on how and by whom these facilities are used. The sailing trail of the Great Masurian Lakes consists of 32 interconnected lakes. 102 marinas with 6752 mooring places and 40 berthing sites (mooring places not counted) are situated on the shores of the lakes (fig. 1). Small and middle size ports dominate in the area (table 2). The shores of Sztynorckie, Niegocin, Tałty, Bełdany and Boczne are the most densely used (more than 20 mooring places per km of the shoreline, fig. 2). The highest number of mooring places is available in towns, with Giżycko being the biggest harbor of the Great Masurian Lakes. Although marinas in the study area are generally well equipped, terms of use of services vary highly. This could result in lower level of customers' satisfaction or in incorrect patterns of use. The project of ecomarinas - modern, nature friendly marinas is recently developed (fig. 3, 4 and 5). New objects have enhanced tourists facilities, but common rules of use of services has still to be developed. The pattern of tourist transfer between water and land depends on availability of services both in marinas and in their surroundings (fig. 6). Sailors who meet all their needs directly in marina are less willing to go outside. At the same time marina that offer wide range of entertainment or gastronomy amenities usually attract also land based tourists. The less services or tourist attractions are available outside, the more people tend to spend their time in the marina itself. Big marinas that offer big diversity of services, for example Sztynort, have high "absorption effect". If the marina has limited offer, but it is situated in an attractive and well developed area, tourists tend to penetrate into its surroundings. The lower is the diversity of facilities both in the harbor and its vicinity, the more homogeneous are users. For example berthing sites have usually just one function - they allow sailors to penetrate the shore. The majority of marinas in the Great Masurian Lakes tend to absorb tourist traffic rather than support further penetration. We suggest that construction of some simple berthing sites could increase transfer of tourists between water and land. This could help to expand tourism offer, make water tourism more profitable and contribute to a better sharing of natural and cultural va lues of the area.
