Functional and structural changes of regional system are ongoing spatial changes that form patterns of spatial organization, depending on dominant regional forces and factors. Spatial structure of West Azerbaijan province experienced significant changes during 15 years; thus, the present research aim to investigate the manner of spatial distribution of two variables of population and activity, ...

Spatial distributions of rural settlements in Iran represent an imbalanced nature. The major objective of this study is to investigate the spatial patterns of Iranian rural settlements using certain indicators and indices .It further tries to propose a model regarding the analysis of spatial imbalances. This study further supported by application of modifiable areal unit problem(MAUP) suitable ...
