Article Citation Count: 0Determining the Effect of Urbanization on the Vegetation of Gurun District (sivas) Based on Biotope Mapping and Vegetation Analysis(Istanbul Univ-cerrahapasa, 2020) Bozkurt, Selvinaz Gülçin; Akkemik, Unal; Kose, NesibeUrbanization is one of the strongest negative effects on vegetational change within and around a city. In this study, it is aimed to determine the flora and vegetational changes within and around the city based on the identification and mapping of the biotopes which show differences in terms of ecologic factors met in Gurun district center and its vicinity and which are suitable for Corine biotope classification. First, 13 main biotope types are classified. In the biotopes, total 666 plant taxa were identified, 84 of which were endemic. Vegetation of the biotopes was determined, and then similarity levels of main biotopes are calculated according to the similarity coefficient method of Sorensen. Accordingly, while the similar areas are health facilities and agricultural areas the most different ones are parks and sports areas and drainage areas. The results emphasize the similarity levels of vegetation in biotopes and the negative effect of human intervention in the study area. As a result, with its rich natural structure, vegetation covers and endemism rate, the district of Gurun has significant natural biotopes and it is suggested that biotope classification should be considered in determining vegetation change and urban planning.Article Citation Count: 6Investigation of Land Cover (lc)/Land Use (lu) Change Affecting Forest and Seminatural Ecosystems in Istanbul (turkey) Metropolitan Area Between 1990 and 2018(Springer, 2023) Bozkurt, Selvinaz Gülçin; Kusak, Lutfiye; Akkemik, UnalThis study was conducted to examine the land cover (LC)/land use (LU) change affecting forest and seminatural ecosystems and the spatio-temporal development of urban expansion between 1990 and 2018 in the city of Istanbul, where urbanization is the most intense in Turkey. For this purpose, using Corine Land Cover (1990, 2000, 2006, 2012, and 2018) dataset, the land cover of the area was determined in 5 different classes (artificial surface, agriculture, forest, water bodies, water), maps were produced, and tabular data were created. The changes in LC/LU between 1990 and 2018 were determined according to the Puyravaud land cover change rate and hot spot analysis methods. According to our findings, we determined that urbanization in Istanbul expanded the most in the east-west direction, and the agricultural and forest areas gradually decreased by 3.02% and 6.66% respectively; urban areas increased at the same rate of 9.69%. It is predicted that this change will continue increasing until 2030 when the forecasting method is applied in the field. It has been determined that the most important reasons for this situation are local government policies, population growth, and economic development initiatives applied in the area. As a result, it has emerged that measures should be taken based on sustainability and naturalness approaches to design urban development plans and to protect natural areas on a large scale, in order to limit possible LC/LU conversion from natural structure to urbanization in the area.Article Citation Count: 1Functional Features and Benefits of Residential Gardens: the Case of Istanbul (european Side)(Aves, 2022) Bozkurt, Selvinaz Gülçin; Yener, Serife Doganay; Akdeniz, Nilufer SeyidogluThis article investigates the extent to which residential gardens affect human welfare in Istanbul (the European side). The developing technology, population growth, and immigration are factors which expose the city of Istanbul to intense construction. Consequently, the gardens in the houses located at the center of Istanbul are decreasing day by day, limiting outdoor activities for the residents, and affecting them physically and mentally. In this study, a questionnaire was applied to 400 people in Istanbul's European side to investigate the extent to which residential gardens affect human well-being. These questionnaires were applied according to five-point Likert scales and the results were analyzed in the SPSS program by applying correlation analysis. The data obtained from the applied questionnaires were analyzed in the SPSS program. As a result of the analysis, it was concluded that residential gardens have a positive influence on the physical and psychological development of people, and also contribute to the protection of nature and biological diversity. Statistically, it has been determined that people mostly use their gardens in the summer months (49.30%) and on the weekends, and spend an average of 0-2 hours (57.50%) in their gardens. In addition, these analyses were associated with participant characteristics such as age (18-25, 26-30, 31-40, 41-50, 51-60, 60 and older), gender (female/male), socioeconomic status (occupation and income) and social demography (change in population). As a result, this study showed that residential gardens in urban areas contribute significantly to people and nature, that more garden areas should be added to the residences to be built in urban areas, and that these areas should be designed in a functional and sustainable way for people to benefit from nature in the best way.
