چکیده

قرارگرفتن در فضای مدرن، افزایش جمعیت و رشد شهرنشینی، شهرها را به کانون تجمع‌های زیستی و فعالیت‌های مختلف تبدیل کرده و آن‌ها را با کمبود فضاهای سبز عمومی روبه­رو ساخته است. از سوی دیگر، گذر از مدرنیته و قرارگرفتن در جهان پسامدرن و نیز به­وجودآمدن حس نوستالژیک در این فضا، نیاز شهروندان برای گذران اوقات فراغت را افزایش داده و سبب گرایش به بازگشت به فضاهای سبز در شهرهای مدرن شده است که این خود آثار اجتماعی، روانی و فرهنگی زیادی را شهرنشینان این فضاها دارد. اهمیت فضاهای سبز شهری تا حدی است که امروزه وجود این کاربری، یکی از شاخص‌های توسعه‌یافتگی جوامع به‌شمار می‌آید. هدف این پژوهش، بررسی فضاهای سبز درجهت رسیدن به استانداردها و وضعیت مطلوب و نیز ارزیابی پایداری شهری از منظر پارک‌ها و فضاهای سبز عمومی در شهر اصفهان است و در آن، به‌صورت تطبیقی، مناطق پانزده‌گانة کلان‌شهر اصفهان بررسی شده است. پژوهش، اسنادی- تحلیلی است و جمع­بندی داده‌های کمی در قالب مدل ضریب پراکندگی، نتیجة نهایی تحقیق را به دست داده است. یافته‌ها در زمینۀ چگونگی توزیع فضاهای سبز شهری در مناطق پانزده‌گانة اصفهان نشانگر آن است که توزیع فضاهای سبز شهری در شهر اصفهان، متعادل است؛ به‌نحوی‌که از این منظر، مناطق شهری 2، 4، 5 و 6 در شرایط پایدار، مناطق 7، 9، 12 و 13 در شرایط نیمه­پایدار و سایر مناطق در شرایط ناپایدار به سر می‌برند.

Assessment of sustainability in Urban Green Space in 15 districts of Isfahan

Extended Abstract
Introduction
Urban green spaces play an important role in improving quality of life and sustainability in cities and require a careful empirical assessment. Several factors such as social, economic, ecological or planning aspects and several functions such as utilization, production, employment, education, regulation and preservation of urban green spaces form the basis for the determination of the criteria and indicators relevant for the assessment of urban green spaces. The city is identified as altered natural environment by excessive changes in nature and increasing presence of manmade structures. Urban green spaces are remnants of nature in this environment and play an important role in ascending the level of life quality in the city. In this study the sustainability of urban green spaces in Isfahan city were studied. The studies indicate a considerable balance and sustainability in urban green spaces with a more intensity in the Isfahan zones.

Methodology
The methodology of this paper is analytical and descriptive and applied in biased on goal. The results of this paper can use in programs and politics in Isfahan municipality. The scale of the research is urban green space in Isfahan city. The data and information collected from Isfahan municipality. For data analysis we use land measurement model, urban green spaces modal and D.V model for urban land diffusion.

Result and Discussion
In land use planning, urban open space is open space areas for "parks", "green spaces", and other open areas. The landscape of urban open spaces can range from playing fields to highly maintained environments to relatively natural landscapes. They are commonly open to public access, however, urban open spaces may be privately owned.
In between urban land use, green spaces are part of the frameworks of the cities, which we refer to as the animate of the framework structure of the city, and in correlation with inanimate of the city; they create the texture and appearance of it. But according to importance of expansion of green space in cities, instead of the development and expansion of these spaces in Isfahan which was someday regarded as the model of Islamic garden –city with appropriate green space, the focus in the recent years have been more on the development of framework- residential, commercial, structures and roads, parking lots etc.

Conclusion
Urban green space provides recreational areas for residents and helps to enhance the beauty and environmental quality of neighborhoods. But with this broad range of recreational sites comes an equally broad range of environmental issues. Just as in any other land uses, the way parks are managed can have good or bad environmental impacts, from pesticide runoff, siltation from overused hiking and logging trails, and destruction of habitat. Lack of community and public access to safe open and green space is a critical area of concern for urban residents in Isfahan city.By allocating mainly open and undeveloped lands to green and open space development, improving average per capita green space is targeted. With considering land availability and differences in population concentration all 15 urban districts faces different limitation and therefore need to adapt different and appropriate strategies. In this paper whole of species of urban space such as parks, green belts, urban green space in street in 15 districts in Isfahan city analyzed. The results show that 4 districts of Isfahan has more urban green space and 11 districts has least urban green space

Keywords: urban green space, sustainability assessment, Isfahan city, Iran.
