an analysis of sustainable regeneration considering urban green infrastructure indicators with an institutional participation approach (case: the city of lahijan)

As an urban life support system and as a new method in planning, green infrastructure design can be more effective in the function of natural systems of cities through integration in the sustainable regeneration processes as well as integrated and coordinated management of organizations involved. multiple management systems and disharmony of state organizations and institutions in charge of urban regeneration in green infrastructure are the main issues in urban management. in this regard, using green infrastructure indicators in regeneration programs, in this research, conducted in lahijan in 2019, the organizational relationships of staff members, including state institutions of the city were examined. also, using a descriptive-analytical method and library information, as well as 400 questionnaires distributed among residents and 50 interviews with city managers as the staff members, after analysis and implication of the data through pearson correlation, spss, and social network analysis in ucinet environment, the connection between urban green infrastructure indicators and sustainable regeneration was determined, and the interactions of institutions involved in regeneration were studied. according to the results of the questionnaires, a significance level of under 0.01 was found for green infrastructure and sustainable regeneration components; therefore, at a certain level, the relationship between the indicators of green infrastructure and sustainable regeneration was measured at 0.95. in terms of environmental indicators, due to higher correlation coefficients and mean, the impact was higher than the other two indicators. state institutions are highly capable of preserving the urban green heritage by increasing inter-institutional interactions and awareness. therefore, to realize this approach, it is necessary to raise the awareness of each institution and collaboration among actors to increase the executive power of the staff committee members. accordingly, the executive power of institutions is based on inter-institutional relations and collaboration and increasing the managers' knowledge about sustainable indicators of regeneration in the rehabilitation of urban green infrastructure of lahijan.
