Abstract

Cities are changing permanently in different dimensions due to human and nature activities. the physical changes are significant and these changes formed in two main patterns (sprawl and compact) so that causing stability or instability. The recognition of physical development pattern of Kashmar city and it’s stability or instability is The purpose of this study. Research method is Descriptive – analytical. Shannon entropy index and Holdern model used for measurement and recognition of physical growth pattern of city. Also spatial autocorrelation technic used for analysis of spatial pattern
of city growth parameters. The results show the physical growth and spatial spread of Kashmar city
have been Inappropriate and ineffective over the last twenty years. Also we can assume dispersed growth pattern or irregular horizontal expansion for the city. Shannon entropy index for 2000 and 2010 years is 1.36598 and 1.36731 that it show horizontal growth with slight increase during a decade. Also the result of holdern model show from total area added to city, during the period under study, %45 is result of population increase and %54 is result of urban per capita increase. It shows instability. The result of spatial autocorrelation about four variable population, household, Residential units and density show the greatest number for density. These reveal cluster and abnormal distribution of density on city area. Household have lowest number so it have relatively normal distribution. with emphasis on results, urban sustainable development and sustainable city growth need to politics for control and change of this kind of growth.
