مدلسازی ساختاری تاثیر ویژگی‌های بصری پارک‌های جیبی بر نتایج احیاکنندگی خستگی ذهنی شهروندان

امروزه پارک‌های جیبی به عنوان جزئی از فضای سبز عمومی می‌توانند سلامت جسمی و روحی افراد را بهبود ببخشند و باعث احیاکنندگی خستگی ذهنی در افراد شوند؛ با وجود این، این مسئله که چه ویژگی‌های بصری از پارک‌های جیبی شهری می‌تواند باعث افزایش نتایج احیاکنندگی ذهنی افراد شود هنوز ناشناخته است و مطالعات کمی به آن پرداخته‌اند. از این رو هدف از این مطالعه، بررسی ارتباط میان ویژگی‌های بصری پارک‌های جیبی و نتایج احیاکنندگی خستگی ذهنی شهروندان می‌باشد. با توجه به موضوع پژوهش، حوزه مطالعاتی و مسائل آن، ترکیبی از روش‌های اسنادی-تحلیلی و پیمایشی استفاده‌ شده است. روش گردآوری اطلاعات پژوهش، کتابخانه‌ای و میدانی بوده است و ابزار مورد استفاده در جمع‌آوری اطلاعات لازم پرسش‌نامه می‌باشد. براساس فرمول کوکران حجم نمونه 384 بدست آمد. محدوده مکانی تحقیق، هشت پارک کوچک شهری از منطقه‌ی یک تهران از بین مناطق بیست ‌ودوگانه و برای جمع‌آوری داده‌های اولیه انتخاب شدند. نتایج حاصل از این مطالعه به ایده‌های طراحان شهری و معماران منظر برای برنامه‌ریزی و طراحی هر چه ‌بهتر پارک‌ها بر اساس ویژگی‌های ترجیحات بصری موثر بر نتایج احیاکنندگی خستگی ذهنی کمک می‌کند.

structural modeling of the effect of visual characteristics of pocket parks on the perception of regeneration of mental fatigue of citizens

introduction: the living conditions in large cities, characterized by constant concerns and long hours spent at a desk, contribute significantly to mental fatigue. this mental fatigue can manifest in various ways, including increased cognitive errors, irritability, distraction, mood swings, restlessness, and decreased efficiency. ultimately, these factors can lead to mental exhaustion and a loss of concentration. in contemporary urban environments, pocket parks—integral components of public green spaces—have the potential to enhance both physical and psychological health, thereby aiding in the restoration of mental fatigue. however, the specific visual characteristics of urban pocket parks that facilitate a sense of mental restoration are not well understood and require further exploration. consequently, this study aims to investigate the relationship between the visual features of pocket parks and the restoration outcomes among citizens. methodology: to address the research topic and its associated issues, a mixed-method approach combining documentary-analytical and survey methods was employed. data collection involved both library research and field surveys, with a structured questionnaire serving as the primary tool. the study utilized closed-ended questions based on visual preference statements, employing a 5-point likert scale where the fifth option indicates the highest level of agreement and the first option indicates the lowest. using cochran’s formula, the sample size was determined to be 384. questionnaires were randomly distributed among users of eight of the most frequented pocket parks in tehran at various times and on different days of the week. to assess the reliability of the questionnaires, 50 were distributed and collected, with cronbach’s alpha coefficient confirming the reliability of each variable as well as the overall questionnaire. results: the statistical data from the current study were organized into tables for analysis. subsequently, all data—including variance and sampling error—were analyzed using lisrel software. the results indicate that the variables of greenery, coherence, complexity, mystery, openness, and legibility account for 47% of the variance in outcomes related to perceived restorative potential. notably, the variable of visual accessibility does not significantly influence restoration outcomes. among the examined variables, legibility exhibits the most positive impact on restoration outcomes, followed by coherence, greenery, openness, and mystery. conversely, complexity demonstrates a negative and minimal effect on restoration outcomes compared to the other variables. conclusion: the findings suggest that visual preference features in urban natural landscapes play a crucial role in restoration outcomes for citizens utilizing pocket parks. this study provides valuable insights for urban designers and landscape architects, enabling them to plan and design parks that prioritize visual preference features that positively influence mental restoration.
