كلان شهر اصفهان به دليل افزايش جمعيت، مهاجرپذيري، گردشگر پذيري، سكون هوا در نيمي از روزهاي سال، خشك سالي در سال‌هاي اخير، واقع شدن در محور مواصلاتي شمال و جنوب كشور، وجود صنايع سنگين و معادن در حريم شهر و...، در حال حاضر با معضل آلودگي هوا روبرو است. از اين رو پژوهش حاضر بر هدف بررسي مولفه هوا كلان شهر اصهان در چارچوب رويكرد شهر سبز، و ارائه راهبردهايي براي تحقق كلانشهر سبز اصفهان در مولفه هوا صورت پذيرفت. در اين پژوهش بررسي وضعيت مولفه هوا كلان شهر اصفهان در چارچوب رويكرد شهر سبز با تلفيق چارچوب فشار - وضعيت - پاسخ با مدل هاي تصميم گيري چند معياره و سپس تدوين راهبردها تحقق شهر سبز اصفهان در مولفه ها در چارچوب جامعهي شامل بهره گيري از ماتريس هاي IFE، EFE، SWOT، IE و QSPM انجام گرفت. نتايج پژوهش حاكي از آن است كه مولفه هوا كلانشهر اصفهان در چارچوب رويكرد شهر سبز از وضعيت مطلوبي برخوردار نيست، به طوري كه سال هاي 1391 و 1388 به ترتيب رتبه هاي اول (۰/۴۹۶) و آخر (۰/۴۱۶) را به خود اختصاص داده بودند و جهت نيل به كلان شهر سبز اصفهان در مولفه هوا، ضرورت دارد تا راهبردهاي تدافعي اتخاذ گردد.

Introduction
Due to the arid and semi-arid climate, recent droughts, the increasing demand for
residence and activity, rapid physical growth, etc. Esfahan metropolis is faced with
several environmental problems. Hence, the present research was an attempt to
propose strategies for optimal management of Esfahan Metropolis by studying the
stresses on the air of this metropolitan city.
Matherials and Methods
In this study, the environmental condition of Esfahan metropolis was examined
within the framework of the green city approach using a combination of the PSR and
MCDM models. Afterwards, the strategies were formulated using the I FE, EFE, SWOT,
IE, and QSPM matrices. Discussion and Conclusion
The green city indices in the air component resulting from the survey of the research
literature and Delphi methodology consist of 33 indices in 19 groups that the index of
the number of natural gas stations has the highest degree of relative significance
(0.0 17299) and the index of the number of taxis in the taxi fleet has the lowest degree
of relative significance (0.013448). The evaluation and ranking of the effective factors
on the air conditions of the Isfahan metropolitan area with the ranking model based on
similarity to the ideal solution (TOPSIS) indicates that the condition of the air
component of the Isfahan metropolitan area in years 2012 and 2009, with the highest
(0.496) and lowest (416.0) similarity to ideal solution, has had the best and worst
environmental conditions, respectively. The study of the internal and external factors
of the progression of the air component of the Isfahan metropolitan area also indicates
the dominance of weaknesses over strengths and threats over opportunities. The
simultaneous analysis of the internal and external factors of air component of Isfahan
metropolitan area with internal and external · matrices indicates that the most
appropriate type of strategies for the realization of the green Isfahan metropolitan area
is the defensive strategies type. Prioritizing the strategies for the realization of the
green city of Isfahan in the air component using the QSPM matrix and the Delphi
group's opinion, indicates that we could suggest the strategy of supervision and
monitoring for protecting and maintaining the land use of farms, orchards, and forest
parks in the boundaries and limits of the Isfahan metropolitan area as the most
appropriate strategy.
Conclusions Research results revealed that the status of the air component of Esfahan Metropolis is not desirable with regard to the green city approach. That is to say, in the study period, from 2012 to 2009 conditions in the city showed the highest (0/496) and
lowest (0/416) similarity to the ideal solution, respectively. Therefore, in order to attain the air-related goals of the Esfahan green city approach it is necessary to adopt
defensive strategies.
