Çalışmanın Amacı: Bu çalışma, tipik dağlık bir havza içeresinde 135441.0 ha alanda 1987 ve 2013 yılı orman amenajman planı verilerine ve nüfus dinamiğine bağlı olarak arazi kullanımında oluşan değişimlerin izlenmesi için yapılmıştır. Aynı zamanda bu çalışma arazi kullanım sınıfının (LUC) şeklindeki zamanla oluşan değişimleri incelemektedir.

Materyal ve Yöntem: Arazi kullanım değişikliklerin zaman ve mekan boyutunda izlenmesi için, 1987 ve 2013 yılı orman amenajman planlarından yararlanılmıştır. Ayrıca, çalışma alanındaki arazi kullanım değişimi için yerleşim alanları etrafında 1000 m zonlama içerisinde incelenmiş ve aynı alanlardaki nüfusun azalması ile ilişkilendirilmiştir. Nüfus dinamikleri (artış veya azalma) orman arazileri üzerindeki kullanım şekillerini de etkilemiştir.

Sonuçlar: 1987 ile 2013 yılları arasında; verimli orman arazileri (saf iğne yapraklı, saf geniş yapraklı ve karışık orman) alanlarında artış olurken, tarım ile kumlu arazilerde azalma meydana gelmiştir. Verimli orman alanlarındaki parça sayılarının artması çoğunlukla bozuk veya verimsiz orman alanlarının ağaçlandırılma çalışmalarından gerçekleşmiştir. Bu artışın nedenleri insanların kentlere göç etmesi ve bakım faaliyetleridir.

Araştırma vurguları: Alucra Orman Planlama Biriminde orman kaynaklarının artmasının en önemli nedenlerinden birinin sosyal yapının zaman içinde önemli ölçüde değişimi olduğu söylenebilir. Ayrıca çalışma alanındaki 1987 ve 2013 yılları arasında ormancılık faaliyetleri de bu artışta önemli bir faktör olmuştur.

Determination of The Effects of Alucra Forest Planning Unit's Population Dynamics on Land Use Changes

Aim of study: This study is done to monitor temporal land use/land cover changes in a typical mountain watershed covering an area of 135441.0 ha in North Eastern of Turkey based on rural demographic dynamics and forest management plans belonging to the years 1987 and 2013 coupled by GIS analyses. It also investigates changes in the shape of land use class (LUC) over the period.

Material and Methods: The changes occurring time wise and positional on the base of the local LUC was examined by benefiting from the forest management plans from 1987 to 2013. Moreover, the change of LUC around these areas has been examined with the 1000 m zones thrown around the settlement areas and correlated with the fast decrease of the population recent years. Demographic dynamics (increase or decrease) affect the usage of forest lands, as well.

Main results: While there was an increase in the productive forest lands (pure coniferous and deciduous, and mixed forest) between 1987 and 2013. In the same periods there was a decrease in agricultural and sandy areas. The increase of patches in the productive forest lands mostly resulted from afforestation works conducted in the unproductive forest lands, and forestry maintenance activities. Another reason for this increase of forest patches is why people have immigrated to urban areas in the last years.

Research Highlights: It can be said that one of the most important causes in the rise of the forest resources in the Alucra Forest Planning Units (FPU) is the time wise changes of social structure. Furthermore, the forestry activities in the study between 1987 and 2013 are also the other significant factor in this increase of forest resources.
