A Boolean Approach in Forest Management

Abstract

Multi criteria analyses have been used mostly to deal with spatial decision problems since their emergence. Spatial multi criteria analysis is different from conventional multi criteria decision analysis (MCDA). Because it includes a geographic component. Multi criteria evaluation (MCE) and multi criteria decision making (MCDM) are very important concepts in Geographical Information Systems (GIS). Many spatial decision problems entail GIS and MCDA integration. GIS-MCDM integration can be thought of a process that uses value judgements and then represents results of these judgements spatially on a digital map. Forestry decision problems involve many alternatives and evaluation criteria. Most of the forest management problems are spatial in their nature and usually involve multi criteria. Fire management is an important component of forest management. In this study Boolean approach is used for the fire management. The areas that can cope with fire effectively are examined according to their distances from water resources, streams and settlement areas criteria for İzmir Forest Administration Chief Office by using Boolean approach. IDRISI Software Package is used for all analyses.

Orman Yönetiminde Boolean Yaklaşımı

Abstract

Çok kriterli karar problemleri ortaya çıkışlarından beri büyük ölçüde konumsal (mekansal) karar problemlerini çözmek için kullanılmıştır. Konumsal çok kriterli karar analizi, klasik Çok Kriterli Karar Analizi (ÇKKA)’dan farklıdır. Çünkü coğrafi bileşen içermektedir. Çok Kriterli Değerlendirme (ÇKD) ve Çok Kriterli Karar Verme (ÇKKV, Coğrafi Bilgi Sistemleri (CBS) oldukça önemli kavramlardır. Birçok konumsal karar problemi CBS ve ÇKKA’nın entegrasyonunu gerektirmektedir. CBS-ÇKKV entegrasyonu, çıkarımları kullanan ve daha sonra bu çıkarımların sonuçlarını konumsal olarak sayısal harita üzerinde gösteren bir süreç olarak düşünülebilir. Ormancılıkla ilgili karar problemleri birçok alternatifi ve değerlendirme kriterini içermektedir. Çoğu orman yönetimi problemi yapısal olarak konumsaldır ve genellikle çoklu kriter içermektedir. Yangın yönetimi, orman yönetiminin önemli bir bileşenidir. Bu çalışmada yangın yönetiminde Boolean yaklaşımı kullanılmıştır. İzmir Orman İşletme Şefliği için yangınla etkin olarak mücadele edebilen alanlar; su kaynaklarından uzaklık, akarsulardan uzaklık, yerleşim birimlerinden uzaklık kriterlerine göre incelenmiştir. Tüm analizler için IDRISI paket programı kullanılmıştır
