    The Contributions of Urban Landscape to Urban Life
    (SELCUK UNIV, 2017) Polat, Ahmet Tugrul; Onder, Serpil; Akay, Ahmet
    The issues of urban and urbanization emerged after the industrial revolution. Thus, cities that have increased rapidly in population have become points of attraction for people. Over the past century, the world population has begun to gather quickly in urban areas. Cities are transforming into unhealthy living environments with distorted ecological balance, lost green areas and aesthetic qualities. The value of accessible green spaces in urban areas is increasing to the unprecedented levels. The green space system seen as a necessity in the cities have provided the emergence of the "urban landscape" phenomenon. The issue of urban landscape is now a very serious concept. The landscape change is moving along with the level of civilization. Primarily, guidance service should be offered for more efficient, comfortable and protective areas. An interdisciplinary approach is needed in the creation of urban spaces. In this study, the term of urban landscape was explained and the researches about the contributions of urban landscape to urban life were examined and suggestions were made about the subject.

    Determination of heavy metal pollution at Mevlana Park (Konya-Turkey) by analysis of soil, grass and cedar tree needles
    (ASIAN JOURNAL OF CHEMISTRY, 2008) Dursun, Sukru; Onder, Serpil
    In this study, soil, grass (mostly Lolium sp.) and cedar tree (Cedrus libani) needles were used for determination of heavy metal pollution level at Mevlana Park in Konya city centre. Heavy metal levels i.e., Pb, Cu, Zn, Co, Cr, V, Cd, Ni and As were investigated in all the samples of soil, grass and tree needles during 2003 and 2004 years. According to the results of this study, there were statistically significant differences for heavy metals contents in the cedar tree needles between the years 2003 and 2004 except, Cd and As. Similarly, measurement for heavy metals contents in the samples of grass and soil collected in 2003-2004 years were also statistically significant different except Cr and Ni. Some of the metals as Pb, Cu, Cr, V and Cd were over the limits values, but Zn, Co, Ni and As were not over the critical levels. Only Cu content was higher in the soil samples, on the other hand, Cu, Cr and Cd content in the grass samples and Pb, V and Cd content in the cedar tree leaves were higher than critical levels for human health.

    The evaluation of existing and proposed active green spaces in Konya Selcuklu District, Turkey
    (ACADEMIC JOURNALS, 2011) Onder, Serpil; Polat, Ahmet T.; Korucu, Sebahat
    Urban green spaces have social, planning, economic and ecological functions. To benefit functions of green spaces, it is important to make sufficient provision of quality and quantity green space within urban areas. In this study, the adequacy of the active green spaces in Selcuklu district were investigated in terms of spatial quantity and access by walking in urban development plans and existing applications using GIS. The results displayed that existing active urban green spaces covered 57 632 75 m(2) area, and the per capita ratio is 12.53 m(2) according to actual urban population. The size of the active green spaces except city parks is below in force standards. 66% of the total district area is not within ideal distance walk to the city parks, 71% to neighbourhood park, 55% to the children playgrounds, and 43% to the sports areas alike. In development plans it has been stated that green spaces are in multipartite and are not defined according to a plan. 21 569 790 m(2) urban area was planned as active green spaces, and 38.38 m(2) per capita was anticipated according to population projection. However, 36.34 % of urban park and 9.68% of other active green spaces was applied until 2010. These results showed that existing active green spaces do not make a sufficient contribution to urban life due to their small areas and disproportionate distributions across the urban. At the end of our research suggestions have been made in terms of planning and designing to have positive contributions to the life of urban dwellers.

    The use of native halophytes in landscape design in the central anatolia, Turkey
    (2018) Sağlam, Coşkun; Onder, Serpil
    In this study, the usability of some herbaceous halophytes grown naturally in salt marshesthat dry most of the year in Central Anatolia Region were investigated in landscapedesign. Within the scope of the research, in the years of 2016 and 2017, seasonal fieldstudies were carried out in saline habitats in the vicinity of Konya, Ankara, Aksaray andNevşehir, and taken photographs and herbarium samples of halophytic plant species. Thegeneral botanical and ecological characteristics of the selected species are given and thevalues used in landscape design have been determined considering the aesthetic andfunctional properties. As a result of the field studies carried out during the vegetationperiods, 59 halophytic plant species, belonging to 38 genera and 19 families that could beused in landscape design were identified. The most representative family was theAsteraceae with 11 species, followed by Plumbaginaceae (9 species) andChenopodiaceae (8 species). The genus Limonium from Plumbaginaceae family is wellrepresented with 8 species for landscape use. The endemism rate of halophytes used inlandscape design is 42% (25 species) in the research area. The most common uses inlandscape design are determined in roof gardens by 49 species, followed in groundconservation and erosion prevention by 31 species. Since these halophytic species, whichare mostly succulent and endemic, are well adapted into both wet and dry areas. Their usein landscape design is of great importance for restoration of arid and barren land, whichmay increase as a result of global climate change, conservation of biodiversity as well assustainable agricultural practices.

    WATER-SAVING OPPORTUNITIES IN URBAN GREEN SPACE APPLICATIONS
    (INT SCIENTIFIC CONFERENCE SGEM, 2010) Onder, Serpil
    Water is the basis of life and is the driving force for economic and social development and for poverty eradication. Agricultural, domestic, industrial, and ecological processes within communities all rely on its quality and availability. Urban green spaces are key ingredients in the cities' sustainability and contribute to the quality of life in many ways by providing ecological performance, psychological, physical well-being and recreational services. However existence and establishment of green spaces in the city centers have a close relation with presence of water. The cost of water used in urban is higher than the water used in agricultural areas, because of that the necessity of the conservation of the water and saving of water used in the urban have to be considered. It was estimated that the water used in urban landscape areas is one of the main factor in saving of water. The 50-70% of the water served by the municipality was estimated to be used in urban green spaces. The seven basic principles of water saving in green space applications are listed below; planning and design, soil improvements, efficient water, zoning of plants, mulches, turf alternatives and proper maintenance. In this study, the principles of water saving were determined by the evaluation of the water conservation programmes, xeriscape and irrigation systems in green space applications.
