摘要: Over the past decades, replacement of natural ecosystems with built-up areas has put cities under increasing pressures, such as degradation in water and air quality. The main natural resource diminished significantly is water. In arid regions of Iran, settlements have traditionally been supported by qanat, which is the oldest and most efficient method of extracting water. Qanats- These sustainable systems- play a vital role in meeting local water needs and have served Iran as the main water supply throughout history. Due to the technological and socioeconomic changes, many of these systems have been replaced and abandoned during the past decades. It is necessary to create suitable solutions to increase the efficiency of qanats in order to achieve sustainable development especially in populated cities. One of the aims of this study is to suggest ways to revive the use of qanat routs in District 7, Tehran. For this purpose, the qualitative method was carried out due to determine the capabilities of urban environment and specify the green patches and open spaces. First of all, field surveys and data collection were conducted in order to detect the exact locations of the qanats’ routes, Identify environmental potentials and opportunities and finally explicate the research participant’ attitudes through map and interview analysis. Another objective of the study is to investigate the power of these systems in planning public open spaces and investigating how revitalization of this ancestral infrastructure can be served to fertilize open spaces, restore the fragmented orchards and bring oxygen to the polluted megacity of Tehran. Finally, an ambience was designed in order to create lively public open spaces and improve the social life in this residential district.
