Mevcut
araştırmanın temel amacı, nesne tabanlı bir görüntü analizi (OBIA) işlemi
uygulayarak Urmiye Gölü'nün kuzey kıyılarındaki Arazi Örtüsü / Arazi Kullanım
Değişiklikleri (LC / LUC) modellerinde değişiklikleri ortaya koymaktı. Buna
bağlı olarak, görüntü işleme prosedürleri aşamasında, Urmiye Gölü
yüzeylerindeki uzamsal değişiklikler, 1987'den 2016'ya kadar Landsat
görüntülerinden dikkatlice alınmıştır. Ardından, ikinci aşamada, Misho Dağı'nın
güney yamaçları için LC / LU değişim modelleri kesin olarak tanımlandı. Elde
edilen modeller, görüntü sınıflandırma prosedürlerinde yaklaşık% 92,54 genel
bir hassasiyet ve% 91'lik bir Kappa katsayısı gösterdi. Son aşamada, Hücresel
Otomata-Markov (CA-Markov) yönteminin tanıtılması ve bir geçiş matrisinin
ayarlanmasıyla, LC / LU modellerinde uzamsal değişiklikler, çalışma alanı
içinde 2020 yılına kadar yaklaşan yıllar boyunca aşamalı olarak simüle
edilmiştir.

Nihai modeller, Urmia Gölü yüzeyinde, belirli su
hacimlerinin eşlik ettiği ve azalan eğilimde anlamlı bir düşüş olduğunu
göstermektedir, bu da tuzlu toprakların miktarının anlamlı şekilde arttığını
vurgulamaktadır. Bu zararlı eğim, esas olarak Urmiye Gölü'nün kıyı
bölgelerinde, kritik bir hiper-salin durumunun eşlik ettiği LC / LU tiplerinde
en son değişikliklerin ortaya çıkmasıyla bitki örtüsünün tiplerinde kritik bir
azalmaya neden olur. Mevcut önemli değişikliklerin uygulanması, yerel biyotik
ve abiyotik bileşenlerin çoğunun ciddi çevresel olumsuz gözlemlerle taklit
tehlikeler içinde olduğuna işaret etmektedir. LC / LU’ta bu tür hızlı bir
şekilde meydana gelen devrim niteliğindeki değişiklikler, acil durumdaki
tehlike ekosistemlerinde ve hassas iklimsel alt sistemlerde var olan çeşitli
kritik etkiler yaratacaktır.

APPLYING AN OBJECT-BASED CLASSIFICATION APPROACH THROUGH A CELLULAR AUTOMATA-MARKOV METHOD IN LANDCOVER/LANDUSE CHANGE DETECTION PROCEDURE "CASE OF THE URMIA LAKE"

The
main aim of the present research was to reveal changes on Land-Cover/Land-Use
Changes (LC/LUC) patterns in the in the northern coast of the Urmia Lake by
applying an object-based image analysis (OBIA) process. Accordingly, in the
image process procedures stage, spatial changes on the Urmia Lake surfaces were
carefully acquired from the Landsat imageries, since 1987 to 2016. Then, in the
second stage, LC/LU change patterns have been precisely delineated, for the
southern hillsides of the Misho Mountain. The resulting models showed an
overall accuracy of nearly about 92.54% and a Kappa coefficient of 91% in the
image classification procedures. In the final stage, by introducing a Cellular
Automata-Markov (CA-Markov) method and setting a transition matrix, the spatial
changes on the LC/LU patterns have been progressively simulated for the
approaching years till year 2020 inside the study area.

The final models illustrate a meaningful significant
decrease in the Urmia Lake surface, accompanying by certain water volumes
diminishing tendency, highlighting the fact that the amount of salty lands are
meaningfully increasing. This harmful inclination has successively causes a
critical diminishing on the vegetation’s types by emerging the most recent
changes on LC/LU  types  accompanying 
by  a  critical 
hyper-saline  condition  mainly around 
the  coastal  parts 
of the  Urmia  Lake.

Implementations of the current significant changes
strongly pointing up that the majority of local biotic and abiotic components
are in imitate dangers with serious environmental negative observations. Such
rapidly occurring revolutionized changes on LC/LU will impose various critical
effects on the existing in danger ecosystems and vulnerable climatic
sub-systems in immediate prospect.
