Abstract:
In this article, the factors affecting the spatial-physical structure of Golhesar village in Rey County, Tehran Province, in connection with the metropolis of Tehran, have been investigated and analyzed. The research method is descriptive-analytical, using documentary data as well as information obtained from surveys. In addition to descriptive methods, the cross-structural analysis technique in MICMAC software has also been employed. The findings showed that over the last six decades, this village has undergone dizzying population and physical growth and has accepted profound transformations in economic and social dimensions. Migration to the village has been realized under the influence of the functions of the Tehran metropolis and the resulting economic transformations in the village. The close distance of 4 kilometers between the village and Tehran has facilitated a change in cultivation from wheat and barley to vegetables in more than 90 percent of the agricultural lands and has increased the need for labor 12-fold. The establishment of industries and massive oil refinery activities, polluting and unauthorized workshops, and activities that are dependent on Tehran in terms of raw materials or markets, as well as the existence and prosperity of the market for simple jobs and especially construction activities in Tehran, have been other influential factors on the spatial-physical structure of the village. The results of the cross-structural analysis also showed that among the 28 identified influential variables, 'weakness of environmental regulations and their enforcement', 'the village's location near Tehran', 'ease of land-use change', 'possibility of voluntary land fragmentation', 'the labor market in Tehran', and 'the possibility of evading regulations' are considered the most key factors.
Machine summary:
The results of the cross-impact structural analysis also showed that among the 28 highly influential identified variables, "weakness of environmental regulations and their enforcement," "the village's location near Tehran," "ease of land-use change," "possibility of spontaneous land fragmentation," "the labor market in Tehran," and "the possibility of evading regulations" are considered the most key factors.
Haghighi Motlagh (1395), in his studies regarding the peri-urban villages of Shiraz, found that the physical expansion of this city has caused numerous structural-functional consequences and transformations in the surrounding villages, including extensive changes in the fields of economic activities, production products, environment, population, texture, and physical form.
The distinguishing feature of this village from other surrounding settlements of Tehran is the widespread influx of Afghan and, to some extent, Pakistani migrants, who constitute a high proportion of the village population and have played an irreplaceable role in the structural transformations of the village through land purchase, construction of residential and non-residential buildings, leasing agricultural lands for work, and conducting both hidden and overt economic activities.
In recent years, more than 350 households of native individuals, many of whom still own agricultural patterns, properties, and farmland, have migrated to the city; in contrast, the several-fold influx of migrants from inside and outside the country (Afghanistan) has caused physical and population growth in the village, such that Quch-Hesar and Old Salambar, which were located a few hundred meters apart and until 50 years ago had less than 3 hectares of residential space, have become connected to each other and now occupy an area of more than 36 hectares under various residential land uses (Golhashar Village Administration, 1395).
