Landscape Optimal Suitability Analysis Method: The Case of Anamur District

Due to the increasing population and life-needs both in the world and in Turkey, most appropriate use of natural resources should be determined. Sustainable development depends on taking the right land use decisions. Productivity of soil structure determines biomass performance of that field. This study aims to determine optimal ways of using Anamur land according to three kinds of land use: agricultural, forest, meadows-ranges. Geographic Information Systems (GIS) assisted Landscape Optimal Suitability Analysis Method (LANDEP) was used in the study. In this scope, absolute evaluation parameters were determined through the review of 27 studies from the literature. These parameters are topography (altitude, slope), soil characteristics (large soil groups, land usability groups), soil restriction factors (erosion, salinity, drainage, stoniness, wetness, soil depth), climactic features (exposure, temperature, precipitation), geomorphological structure, current land use status. Sub-criteria, standards and significance of these criteria were determined in line with the current research and their suitability were evaluated according to type of land use. Lands were classified as suitable and unsuitable lands and �Agricultural, Forest and Meadow-Range Landscape Suitability Maps� were generated through grading. When the research area was evaluated in terms of suitability (1st, 2nd and 3rd grade), 46% are suitable for agriculture, 96% are suitable for forest and 5% are suitable for meadow and range. Primary land use type in terms of production capacity were determined with suitability comparison and suggestions were offered by creating �Combined Suitability Map�.

Keywords: Analytical hierarchy process, meadow-range; geographic information system; multi-criteria decision-making model; ecological planning; optimal suitability analysis; forest; agriculture.

Gerek d�nyada gerek T�rkiye�de, artan n�fus ve ya�amsal gereksinimler nedeniyle, do�al kaynaklar�n en uygun kullan�m �eklinin belirlenmesini gerektirmektedir. S�rd�r�lebilir kalk�nma do�ru arazi kullan�m kararlar�n�n al�nmas�na ba�l�d�r. Toprak yap�s�n�n sahip oldu�u �retim yetene�i o arazinin biyok�tle performans�n� belirler. Bu ara�t�rmada tar�m, orman, �ay�r ve mera olmak �zere bu �� kullan�m t�r�ne g�re Anamur �l�esi topraklar�n�n en uygun arazi kullan�m bi�iminin belirlenmesi ama�lanm��t�r. Co�rafi Bilgi Sistemleri (CBS) destekli Optimal Peyzaj Uygunluk Analizi Y�ntemi (LANDEP) uygulanm��t�r. Bu kapsamda 27 literat�r incelenerek mutlak de�erlendirme parametreleri tespit edilmi�tir. Bunlar topo�rafya (y�kselti, e�im), toprak yap�s� �zellikleri (b�y�k toprak gruplar�, arazi kullan�m kabiliyet s�n�flar�), toprak k�s�tlay�c� fakt�rler (erozyon, tuzluluk, drenaj, ta�l�l�k, �slakl�k, toprak derinli�i), iklimsel �zellikler (bak�, s�cakl�k, ya��), jeomorfolojik yap�, �imdiki arazi kullan�m durumudur. Ara�t�rma alan� �zelinde bu kriterlerin alt kriterleri, �l��t ve a��rl�klar� belirlenerek alan kullan�m t�r�ne g�re uygunluklar� de�erlendirilmi�tir. Uygun, uygun olmayan alanlar olarak araziler s�n�fland�r�lm�� ve derecelendirilerek �Tar�m, Orman ve �ay�r- Mera Peyzaj Uygunluk Haritalar�� retilmi�tir. Ara�t�rma alan�n uygun alanlar toplam� (1., 2. ve 3. derece) kullan�m t�r�ne g�re de�erlendirildi�inde; %46�s� tar�ma uygun, %96�s� ormana uygun, %5�i �ay�r ve mera potansiyeline uygundur. Uygunluk kar��la�t�rmas� ile alan�n �retim yetene�i bak�m�ndan �ncelikli kullan�m �ekilleri belirlenmi� ve �Karma Uygunluk Haritas�� olu�turularak �neriler getirilmi�tir..

Anahtar Kelimeler: Analitik hiyerar�i s�reci, �ay�r-mera; co�rafi bilgi sistemi; �ok kriterli karar verme s�reci; ekolojik planlama; optimal uygunluk analizi; orman; tar�m.
