Following the influence of this word in the literature related to this field can be searched in 1975 and the writings of William Marlins on the fields of livable in Saturday Review and Christian Science Monitor magazines. The concept of capabilities has recently been the main concern of geography and urban politics. In recent years research and development has attracted a lot of attention in livable cities. In the meantime, the cities have faced many challenges in economic, social and environmental issues to day.Tabriz is one of the Iran's oldest cities. Considering the rich historical, economic, cultural, health and industrial backgrounds of Tabriz city, that the city become the first in different areas. To day not only this way the current study aims to assess the environmental sustainability of Tabriz urban environments.

Indicators based on this research, we intend to answer this question which is in terms of the livability of ten regions of Tabriz city in different dimensions?

The findings show that the existing situation of Tabriz livability due to the average total of ten regions in all dimensions is in the low level, with this finding of the research of Rashidi (1395) who have evaluated the livability of the Tabriz region in comparison with the Osko, Bostanaba, Shabestar and Harris moderat, is alignment.This findings with the findings of Roustaee (1392) who ranked the region 2 in terms of spatial justice in the distribution of urban services in the first priority is alignment.Also this finding of research with finding of Zarrabi (1394) that the citizens' satisfaction level of urban environment has examined the ten regions of Tabriz and they have concluded that urban region 2 and 5 have been in the first priority of the level of satisfaction is alignment as well as the results of the research with the results of Mofarah Bonab (1397) that the evaluated and analyzed the stability situation in the ten regions of Tabriz and they concluded that the 8th region is the most stable and the 3rd region is the most unstable region in Tabriz is not aligned and only in terms of the whole ten regions of Tabriz have been evaluated by the average Stability value is aligned.

According to Kruskal-Wallis results a significant difference between the 10 regions Tabriz of in terms of the desirability of livability indicators.Also, according to the research findings, it is generally concluded that the average obtained in urban services and infrastructure (2/84) is lower than the average and is statistically significant. Because its Sig value is less than 0/05, the average obtained in the urban environment (2/74) is lower than the average and is statistically significant. Because its Sig value is less than 0/05, the average in the urban economy (2/36) is lower than the average and is statistically significant. Because its Sig value is less than 0/05, the average obtained in urban management (2/36) is lower than the average and is statistically significant. Because its Sig value is less than 0/05, the average obtained in urban history (2/39) is lower than the average and is statistically significant. Because its Sig value is less than 0.05 and the average obtained in the urban community dimension (2/98) is lower than the average and is not statistically significant. Because its Sig value (0/650) is greater than 0/05.The results of Kruskal-Wallis test in Tabriz regions indicate that the results achieved in the significance level of 99% and with an error value of less than 0/01 are statistically significant.
