تحلیل توزیع فضایی در میزان دسترسی به پارک‌های ‌شهری (نمونه موردی: شهر زنجان)

کیفیت محیط شهری از برآیند کیفیتِ اجزای متشکله در فضاهای معین شهری حاصل می شود. رسالت برنامه ریزان شهری است تا با ادراکِ منطقی که از کنشِ بین فضا و اجتماع دارند، سطحِ تفکر دسترسی برابر به فضای سبز شهری را برای همه طبقات اجتماعی بر مبنای اصول پایدار عملی سازند. ازاین‌رو هدف از پژوهش حاضر، شناخت و ارزیابی نحوه ی توزیع فضایی پارک ها و میزان دسترسی شهروندان در نواحی شهری زنجان می باشد. لذا در این مطالعه پس از انتخاب مناطق شهری زنجان به‌عنوان جامعه آماری پژوهش، با روش توصیفی – تحلیلی به کمک مدل ها و آمارهای فضایی در محیط جی‌ای اس به تحلیل فضایی مناطق شهری زنجان از منظر پایداری محیطی پرداخته‌شده است؛ که درنهایت یافته های پژوهش نشان داد که حوزه تحت پوشش پارک ها در مقیاس عملکردی با یکدیگر تلفیق‌شده و نقشه های overly شده به‌خوبی نشان داد که نواحی 103، 201، 202، 203، 204، 205، 305 فاقد هرگونه دسترسی می باشند و در بسیاری از مناطق مانند منطقه 102 و 109 دسترسی به پارک ها برای کل ناحیه یکسان نمی باشد و بسیاری از محلات از این دسترسی محروم‌اند. پس چرایی این مسئله که چرا جمعیت تحت پوشش پارک ها 187454 نفر می باشد، و تنها مقداری کمی از جمعیت کلی شهر زنجان (386851 نفر) را تحت پوشش قرار می دهد، این بود که شعاع عملکردی پارک ها اغلب با یکدیگر هم‌پوشانی دارد و این باعث شده است که نواحی مختلف شهر دسترسی یکسانی به پارک‌ها نداشته باشند. نهایتاً مدل ویکور نیز نشان داد که ناحیه 7 از منطقه 1 و ناحیه 12 از منطقه 3 اولین و دومین رتبه و نواحی 2 از منطقه 2 پایین ترین رتبه را دارند.

Analysis of spatial distribution in access to urban parks

Introduction:This is an interstellar green space that is considered as one of the most important factors in shaping social sustainability and urban solidarity and plays an important role in strengthening the minds and minds of citizens in cities It is based on the fact that when comparing cities based on environmental indicators at the international level, one of the most important indicators is the existence of public facilities such as urban parks and citizens’ access to them, which indicates the developmental index of a city in comparison with Other cities are about the quality of citizens’ bioavailability Therefore, the necessity to pay attention to sustainable urban development approach in the planning and review of justice based on the process of allocation of interior space of the green space, taking into account social and functional concepts in equal access to urban green spaces for all of the main topic of today’s studies. It is considered. Materials Methods: Considering the fact that in this study the distribution of space is evaluated using the network analysis of the network, the fourth part of the network analysis functions, answering this assessment, can analyze the network to calculate the actual distance and movement along the street to the local park Execute. As the development of precise descriptive systems for recording green space profile is a clear example of the application of access studies using Network Analysis.Results Discussion: Analyzing the interaction between urban green space and community to understand social injustice is the task of urban planners, with increased access, leads to encouraging community creativity, creating a good and exciting landscape and accurate implementation of the sustainable principles of urban green space users; Hence, the most important mission of planners and city managers in this field is to try to achieve the goal of equal opportunity in accessing the various groups of urban communities to service centers and eliminating conflicts in providing education, health, services, and the like. . Access radius for any user can be different and covers a range of distances. A very important indicator of fair access to urban services is the user’s user access radius. Park on the scale of quarter: The number of these parks in Zanjan is 13, but of this number, 3 are in the 206 area and 2 in the 309 area and the park area: the number of these parks is 7, each of them there are 1 parking area in these areas. Access to all parks in different levels of Zanjan’s areas: In this section, the radius of access to all Zanjan parks with each degree of functional radius that they have combined are based on which the deprived and deprived areas, The population and covered area were determined, and the results can be seen in Table 7 and Map 6. Conclusion: This research has been used to determine the accessibility of different areas to urban parks using the NETWORK ANALYSIS method in the ARC GIS software and in the ARC MAP environment. Two methods have been used to determine how different areas are accessed and how much they are. First, based on the functional radius of each of the parks, according to the park’s functional scale, and the second access based on the time index, access to the results of the Wicker model also showed that in this method, as inferred from the table, area 7 District 1 and District 12 District 3 are the first and second rank and regions 2 of Zone 2 are the lowest. It should be noted that in this model, the analyzes, in addition to quantitative evaluations, also result from initial qualitative evaluations
