| This study is trying to detect land cover changes in coastal areas of Bushehr province using cross
classification and tabulation analysis. Land cover changes detection have done using Landsat satellite
images belonging to the years 1987, 2001, 2006, and 2011. Results showed significant changes in the
study area in the last 23 years by converting the 20807 ha of open spaces and 3724 ha of farm lands to
residential lands. Also, 67890 ha from farmlands are converted to open space and other covers are changed
too. The result of Kappa Index Agreement (KIA) analysis showed that most and least amounts of changes
have been occurred in 2006-2010 (KIA: 0.9212) and 1988-2001 (KIA: 0.9506), respectively. Therefore,
the results of this research shows unbalanced land cover changes in coastal areas of Bushehr province. The
farmlands decline for increasing the residential development and loosing farm land are most important
examples of changes. Therefore, with the current trend of degradation, environmental and social problems
will threat the future situation of coastal areas of Bushehr province. |
