Knowledge of qualitative and quantitative characteristics of changes are extremely important in environmental planning, land use planning and sustainable development. Currently, using vegetation maps is one of the key factors in data production for macro and micro planning. In this research, information of Landsat ETM + and OLI sensors were used to display the temporal and spatial changes of vegetation in Behbahan city in 1999 and 2013 and the value of NDVI index was calculated for two years. In order to evaluate the quality changes of vegetation, the numerical values of the index were classified into 4 classes of different lush green vegetation including land with excellent, very good, good, and poor coverage. Then, the changes were determined using CROSSTAB. The results showed that the qualitative and quantitative changes in vegetation for the study area have been extensive over 14 years, so that, the area of lands with excellent, very good and poor coverage has increased and the area of landswith good coverage, has decreased. The greatest increase in areashas occurred in lands with excellent coverage, so that, it has increased from 5069.76 hectares (ha) in 1999 to 7735.5 ha in 2013. Also, the highestdecrease in areas has occurred in lands with good coverage thathas reached from 34061.4 ha to 27434.43 ha. Finally, the regression equation was obtained to show better relationship between the two parameters of vegetation and temperature. The results confirmed the point that the areas covered with vegetation have lower temperature and vegetation has cooling effects on the surrounding. Therefore, the degradationof the region’s vegetationwill be followed by the warming of the city and many other environmental consequences.

Tourism and tourism economics are becoming one of the pillars of the world's commercial economy. In addition, many planners and policy makers consider tourism industry as the main pillar of sustainable development. Travelers and globetrotters are important sources of foreign currency, and governments are working day by day to expand the tourism industry and its new options. In this regard, ecotourism is a kind of tourism that, while preserving natural resources, maintains the well-being, comfort and values of the local people. In this paper, ecotourism and its developmental issues and tourist attractions are described, and ecotourism is considered as a desirable option for the development of tourism in the world as well as in Iran, and it is generally inferred that due to the position of Iran among the first five countries benefiting from the broadest climatic variation in the world, conditions are favorable for any ecotourism investment in Iran. The present research is theoretical and descriptive, conducted through the review of secondary sources and Internet search. In this article, we describe the ecotourism and its concepts, attractions of nature tourism, as well as the ecotourism attractions of Iran.
