Dynamic analysis for vegetation coverage change in Hoboksar based on dimidiate pixel model
In this study, we monitored the changes of vegetation coverage based on the normalized differ- ence vegetation index and the dimidiate pixel model, using of MODIS remote sensing data of Hoboksar from 2003 to 2010 in August of each year. We focused on the spatial distribution of vegetation coverage of the different levels and the change of vegetation coverage in this area. The results showed that the vegeta- tion fraction decreased gradually from north to south in Hoboskar. Over the past eight years, the vegeta-tion coverage in Hoboskar was increasing slightly, and the highest coverage had reached 91.18% in 2005. In some years, the vegetation coverage decreased slightly compared with those in the previous years. These results indicate improved ecological environment in Hoboskar County.
