Abstract :

One of the main challenges in big cities, especially in metropolitan cities, is rapid population growth regardless to services capacity and facilities responsive to essential needs of citizens. . Hence, in this study, region 4 of Tabriz city has investigated as one of the most crowded zones of Tabriz with index of green space , road network and waste . carrying capacity plays an important role in the environmental sustainability of cities, so that it creates a balance between population and resources in an area. Preservation of resources with desirable quality leads to future generations. The dominant approach to developmental-applied research and research methods is descriptive-analytical. The main research approach is developmental-applied,descriptive,analytical, and survey research.To determine the range capacity, first the productivity potential of each resource is estimated and then based on the population, the amount of thresholds is expressed and compared with environmental standards, after combining and combining the data to prepare a map in the GIS environment. Results show that urban green space with a population capacity of at least 659617 and a maximum of 7420690 people in front of a population of 325898 people in region 4 is in good condition Waste index with a capacity of at least 150,000 people and a maximum of 240,000 people was in an unfavorable situation due to the population of the region.Also, in the field of road network index with a population capacity of at least 96384 and a maximum of 112544 people in front of the population capacity of the region is in a critical pressure range.
