    Analysis of activity, space and user relations in urban squares
    (Sage Publications Ltd, 2020) Acar, Habibe; Yavuz, Aysel; Eroglu, Engin; Acar, Cengiz; Sancar, Cenap; Degermenci, Ahmet Salih
    With the increasing density of built spaces in urban areas, the need for open spaces increases every day. Squares are one of the most important of these open spaces. Urban squares allow various activities and exhibit functional differences based on location and culture. The diversity of activities conducted in squares is extremely important for the quality and viability of liveable urban spaces. Urban residents prefer spaces that are suitable for individual requirements and desires and allow for a variety of activities. These spaces also contribute to social life. This article aimed to determine the user profile, occupancy, facilities and activity diversity at the Ataturk Plaza (Trabzon urban square) in Trabzon, the capital city of Trabzon Province, Turkey. The occupants of the square and their numbers were analysed via the behaviour observation method. As a result of the observations conducted in the square over one year, 17 activities were identified. The majority of these activities were necessary activities and that the most common activity was walking. The occupancy density and distribution in the square were analysed using the Geographical Information System (GIS). These research findings and analyses could serve as a guide for future urban square and urban open space designs.

    ECOLOGICAL AND VISUAL CHARACTERISTICS OF NATIVE PLANT COMPOSITIONS IN MOUNTAIN FORESTS
    (Parlar Scientific Publications (P S P), 2018) Eroğlu, Engin; Acar, Cengiz; Meral, Alperen
    Plants are important components of native landscape should be handled in accordance with their features, enabling them to be recognized, defined and utilized in natural and cultural environments. Road corridors are the best places to observe changes related to succession and fragmentation in native vegetation in the mountainside. In the present study, carried out in the road corridors in the mountainside within the boundaries of Trabzon province in Turkey. It was aimed to define the vegetation visually and ecologically based on the native landscape features. While native plant compositions were ecologically defined, they were approached as an ecological corridor. Patch Analyses based on landscape metrics in the vegetation around this ecological corridor were carried out via GIS. As for visual studies, photographing, visualization and surveys were used to define the design elements and design principles of plant composition and the visual effects they had. Thus, come up in planting design, it was determined according to which design principle design elements came together and what kind of a visual effect appeared. In the final phase, the relationships between the values produced by ecological and visual parameters were stated. Consequently, some significant relationships were found out between patch analysis metrics and visual parameters, area metrics and potential effect of seasonal change of native compositions, habitat features and fragmentation values etc.

    Landscape values of rocky habitats in urban and semi-urban context of Turkey: A study of Tokat city
    (Wfl Publ, 2013) Acar, Habibe; Eroğlu, Engin; Acar, Cengiz
    Tokat is a characteristic city an unusual topographic structure including different land use and green areas in Turkey. The natural landscape values of green areas considered as nature splits withstanding against the urban pressures in the city and surroundings have been offered for implications for urban nature conservation and management. Therefore, this paper presents results of an attempt to assess landscape values of urban rocky habitats comprehensively, and evaluates a proposed systematic landscape value assessment approach for determining environmental perception and preferences of urban rocky habitats which are threatening within excessive urbanization and human use of natural areas in the context of the city of Tokat, Turkey. By using a questionnaire and landscape assessment approach, a total of 20 habitats selected from urban and surroundings were surveyed and with surveying performed on 170 participants, public preferences and landscape attributes for these habitats were determined. According to preferences and performed factor analysis results, gathering perceived data was used to describe and formulate a landscape model for rocky landscapes revealing the 'ecological and spatial', the 'visual/aesthetic' and the 'usage and arrangement' components of the scenes based on principal component structure of factor analysis. Consequently, some suggestions were also made regarding the landscape values in urban context of Turkey and the potential benefits of the method for urban nature conservation and management processes are discussed.

    A Visual Assessment of Roadside Poplar Plantings in Turkey
    (Ankara Univ, Fac Agr, 2018) Eroğlu, Engin; Acar, Cengiz
    Roadside plantings along urban and rural road corridors are designed to create visual effects as well as to provide functional benefits such as shading, screening or routing. Considering their potential for daily public use, roads and road corridors, as significant visual impact centers, can attract people's attention and affect their points of view. Poplar species, which grow rapidly and easily along road corridors and can adapt to different ecological conditions swiftly, are used widely in both urban and rural landscapes in Turkey. The main objective of this study was to determine the visual structures dependent on the mad-plant relationships of the poplar compositions that play an important role in shaping the roadside landscapes. For this purpose, compositions of poplar trees in selected urban and rural road corridors throughout Turkey were photographed and visual analysis techniques (VATS) were applied to determine visual preferences. Participants (n= 35) were shown 30 photographs, selected from the nearly 1000 taken, of road corridor poplar plantings and their evaluations were recorded in a questionnaire. In this survey, the people were requested to evaluate their appreciation levels towards the plantings as well as to express their other visual preferences and to assess visual quality. In addition, the association of all these evaluations with the demographic characteristics of the participants were determined. A correlation analysis was then performed to identify the relationships among all the visual assessments and a cluster analysis was conducted according to the visual status of the photographs in order to determine their groups. In the results of the study, the poplar trees, either individually or in the form of compositions, were reported to have a significant visual diversity. Moreover, the cluster analysis found the resulting three groups to be associated with leaf density, seasonal conditions and the trees as individuals or in groups. The seasonal variation factor in particular was shown to be visually effective in the poplar compositions. It was determined that visual perception of the poplar plantations differed in accordance with the demographic differences. This work established that poplar plantations as single trees or in groups and their proximity to the road altered visual preferences, and consequently, some suggestions were made concerning the use of poplars in roadside landscape planning.
