Investigating the effects of urban creep of Anzali port on the changes or physical-spatial stability of peri-urban settlements

During the last 20 years, Gilan province has always been at the center of immigration and population growth in big and small cities. The city of Bandar Anzali has also been severely affected by the mentioned conditions, so that it has increasingly expanded towards its surroundings during recent decades. The phenomenon of creeping in Anzali city is increasing and it has become the basis for physical-spatial changes in the peri-urban settlements of these areas. The physical expansion of the city of Bandar Anzali has caused the annexation of settlements and their integration. The purpose of this thesis is to investigate the various dimensions of the effects of the urban creep of Bandar Anzali on the physical-spatial stability of peri-urban settlements in the physical-infrastructural, social and cultural, economic and environmental dimensions. The results show that there is a correlation between the indices of urban creep and the stability of the studied settlements with a coefficient of 0.638. The adjusted coefficient of determination also shows that 64.8 is the stability of rural settlements through the linear combination of four indicators. Added value of land, improvement of economic status, optimal access to services, diversity in spatial structure, vitality have a greater contribution than other sub-criteria in predicting the dependent variable compared to other variables, and the least effective in the environmental field with the sub-criteria of cleaning and waste. , environmental pollution and the landscape of green space are observed. The physical index had the greatest impact on the sustainability of the studied peri-urban settlements, and the environmental index with a coefficient of 0.352 had the least impact on sustainability
