Livability is a new concept in the sustainable development paradigm that provids the basis to achieve sustainability. The purpose of this study is to analysis the environmental livability of rural settlements in Somehsara County. This research is applied in terms of purpose and descriptive-analytical methodology.The statistical population of the research is 22790 households in the villages of Somehsara County. To achieve the goal, library resources and field studies were used based on the distribution of questionnaires and interviews with 377 heads of households living in sample villages (20 villages selected by stratified random sampling). To analysis environmental livability, four indices of pollution (environmental quality), green space, rural landscape and resilience (19 items) were examined. One-sample T-test analyses were used to prove the significance and generalizability of the research results, regression analysis was used to determine the impact of environmental indices on the livability of rural settlements and path analysis was used to determine the impact of indicators on livability. Using a single sample t-test, it was found that the average environmental dimension is lower than the expected one. The results of regression analysis indicate the high explanation power of the environmental dimension in relation to the changes in the livability of rural settlements in the County of Somehsara. The results of path analysis showed that the amount of direct and indirect effects of the four indices of environmental dimension on livability was equal to 1.628. Rural landscape index has the highest direct and indirect impact on livability (0.732) followed by resilience, green space and pollution indices on livability, respectively.
