Abstract

The increasing population, growth in national income and migration from villages to cities resulted in urbanization in Turkey in recent years. Trabzon is one of those intense urbanization cities having advantages on trade, education and health seen as the most developed city in Eastern Black Sea Region. Yomra district is quite standing out in Trabzon city expanding to the west, east and high lands directions.

 

In this study, spatiotemporal changes in Yomra district nearby Trabzon city was examined with the help of GIS (Geographic Information Systems). As the main data source forest management plan stand type maps of 1970, 1984 and 2009 were used for the 27 241.3 ha research area. Since the map of former two periods were not available digitally, at first those maps were scanned, coordinated, digitized and spatial database were established. Then, the spatiotemporal changes of selected five land use classes were investigated as productive and degraded forests, settlements, agricultural lands and other uses. Among them settlement and agriculture lands were further analyzed using digital contour curves. Thus, the expansion of settlement and agriculture areas towards to high lands and coastal zone were displayed.

 

The obtained data from three different periods demonstrated striking results that productive forests increased from 3810.3 ha (% 14.0) in 1970 to 9878.7 ha (% 36.3) in 2009, while settlements decreased from 604.2 ha (%2.2) to 403.1 ha (%1.4) in the same period. On the other hand, it is found that settlements areas were spread out to suitable areas for habitation close to the city center especially along the coast and towards the south to the high lands. Average altitude of settlement and agriculture areas were decreased from 419 m to 215 m and 579 m to 456 m respectively between the two periods. Moreover, those land covers were spatially come closer to the coast zone with a decrease in average distance to the sea from 6.8 km to 3.1 km and 6.4 km to 5.0 km.
