Çanakkale ili Arazi Kullanim ve Bitki Örtüsü Degişiminin Uzaktan Algilama Yardimi ile Belirlenmesi

Abstract

Çaliçmada 2000, 2006 ve 2010 yillarinda aliñan Landsat TM/ETM uydu görüntüleri kullanilarak Çanakkale ilinin "orman", "mera", "tarim", "su", "yerleçim- çiplak alan" smiflarmí içeren Arazi Kullanim ve Bitki Örtüsü (AKBÖ) haritalari yapilmiçtir. AKBÖ smiflarmín alanlari hesaplanarak 2006-2000, 2010-2006 ve 2010-2000 yillari arasmda meydana gelen degijimler karçilaçtirilmiçtir. Dogruluk analizleri ve kappa istatistikieri her ilçe için hesaplanmiçtir. Ayvacik ilçesi'nde 2006 ve 2010 yillarinda en büyük alanin sirasiyla, %40.13 ve %42.70'le tarim alanlarmin kapladigi görülürken, en az alanin ise su smifmda oldugu görülmüctür. Bayramiç ilçesinde 2000, 2006 ve 2010 yillarinda en yüksek alanm orman sinifina ait oldugu, su ve yerlejim-çiplak alanlarin %1'in altinda bir alana sahip oldugu belirlenmi§tir. Merkez ilçe, Biga, Çan, Eceabat, Lapseki ve Yenice ilçelerinde orman alanlari en büyük alani kaplarken, su sinifi en az alani kaplamaktadir. Eceabat Ilçesi'nde her uç yilda en az oran yerleçim çiplak alanlarda görülmüctür. Ezine ve Gelibolu ilçelerinde en büyük arazi grubu tarim alanlariyken, en az alanin su smifinda oldugu gozlenmiçtir. En yüksek ortalama smiflama dogrulugu 2000 yili Merkez Ilçe AKBÖ haritasinda iken (% 90.20), en dücük ortalama smiflama dogrulugu Bayramiç Ilçe'si 2000 yili haritasindadir (% 80.39).

The Landsat TM/ETM+ images obtained in 2000, 2006 and 2010 were used to generate Land Use and Land Cover (LULC) maps of Çanakkale province including "forest", "grassland", "agriculture", "water" and "residential area-bare soil" classes. Areas of LULC classes were calculated; changes between 2006-2000, 2010-2006, and 2010-2000 were compared. Accuracy assessments and Kappa statistics were calculated for each district. ln Ayvacik, most of the areas were covered by agricultural lands in 2006 and 2010 with 40.13% and 42.70% respectively, while the least area were covered by water class. In Bayramiç, while most of the areas were covered by forests in each year, the residential areas and water surfaces were covered less than 1% of total area. In Main Municipal district, Biga, Can, Eceabat, Lapseki, and Yenice, the most of the areas were covered by forests, and water surfaces were covered the least area. In Eceabat, the minimum coverage rate was seen in Residential area Bare soil class for every year. In Ezine and Gelibolu, while agricultural areas were classified as the major land cover class, the minor land cover class was classified as water. The maximum accuracy was found for LÜLC map of Main Municipal district in 2000 (90.20%) while the minimum accuracy rate was found for Bayramiç LULC map in 2000 (80.39%).
