طراحي پارك با رويكرد پايداري در دره ي ورديج شهر تهران

Sustainable Park design in Vardij valley of Tehran

تخريب رود – دره هاي شهري از مهم ترين مسايلي است كه پايداري اكولوژيكي شهر تهران را تهديد مي كند. در اين راستا هدف از طراحي پارك هاي پايدار، ايجاد مكان هايي است كه نياز به انرژي هاي تجديدناپذير را به حداقل ممكن برساند و رابطه مردم با محيط زيست را بهبود بخشد. در اين مطالعه يكي از رود – دره هاي شهر تهران؛ دره ورديج جهت طراحي انتخاب شد و فرايند برنامه ريزي و طراحي پايدار با تاكيد بر لايه پردازي ساده اطلاعات انجام شد. با شناسايي امكانات و محدوديت هاي بستر طرح، محل هاي مناسب جهت توسعه شناسايي گرديد و كاربري هاي سازگار جهت توسعه مشخص و اقدام به جانمايي و طراحي آن ها گرديد. با توجه به اينكه رود – دره ها نقش مستقيم بر محيط پايين دست خود دارند؛ طراحي موثر چنين محيط هايي راهكاري جهت رسيدن به پايداري شهري نيز محسوب مي شود.

The needs and characteristics of Tehran Metropolitan and the need for developing recreational places require goal setting and special planning from various view points, specifically in environment. The requirement is vital in conducting comprehensive development programs and natural resource preservation. Regarding the environment destroying process in mountainous regions, especially in south Alborz, along with other factors as- geographical situation, increasingly population growth, urban development and the citizensʹ need to leisure time and escaping from daily life stresses, make the importance of the region more obvious. Destruction of urban river valleys structure is one of the most important problems facing the environment and sustaining ecology of Tehran mega city. For their important functions in providing necessary spaces and recourses and strengthening the sustainability between green-open spaces in urban areas. This problem roots in the lack of notice for structure and function of natural corridors in urban planning. The main purpose of sustainable parks design is to create spaces that minimized the need to non-renewable energies and improve on connection between people and environment. Sustainable design is considered as important things to reach sustainability. In this paper one of the river valleys of Tehran which settled in region 22 of municipality, named Vardij valley has selected to designing sustainable park and the process and programming of sustainable design have done by emphasizing in simple layering of information. At the first with regarding to main road that connect municipality to site, a part of site selected to designing. Then basic environmental inventory about erosion and deposition, climate and air quality, plants and vegetations, geomorphology and geology, geological faults, surface water, outcrops of rock and…of site, have done and important data have collected in strength and weakness map. Then according to observation studies in site and visual attributes of inside the site and around it, analyzing of site have done. Then planning process in sustainable parks with regarding to local characteristic of site has done. With recognition of strength and weakness of site, the best places to developing have cleared and compatible and appropriate uses to developing of site specified with sustainable parks design principles .According to the principles of hierarchy for assessing the structure and function of river valley of Vardij, firstly in comprehensive level 15 zone specified, then possibility functions of each zone specified. Then according to natural and artificial characteristics and qualities of site, and landscape ecological analysis of site, a space near river basin and main road selected, and with approach of patches and corridor it has design. The patches consist of picnic places, parking, and other uses that need in camping sites, and the corridor consist of connecting way and river between patches. These methods in addition of having good effect on landscape aesthetics, can managing water, energy and soil in comprehensive With regarding of river valleys importance as natural element in up-level of Tehran and its direct effects in down-level that is Tehran city, effective design of such places considers as notable pattern to reach sustainable city.
