Abstract
This paper was intend to reveal the changes and grasp the trend of vegetation coverage in Shijiazhuang from 1995 to 2015. Firstly, dimidiate pixel model was used to calculate 6 periods of fractional vegetation coverage in Shijiazhuang based on Landsat TM/OLI data of 1995, 2001, 2007, 2009, 2012 and 2015, then CV model and Slope model were used to analysis spatial change characteristics and the trend, finally CA-Markov model was used to predict the vegetation coverage condition in Shijiazhuang in 2018. Results showed that the average of fractional vegetation coverage increased 3.71% from 1995 to 2015; the average CV of the whole city was 0.211, the main reason for vegetation coverage changes is human intervention; almost invariant and three levels of getting better areas were 82.22% of the city, three levels of getting worse were distributed in urban construction and economy development active areas; by 2018, the areas of high and medium-high vegetation coverage in Shijiazhuang will decrease, the areas of medium and low vegetation coverage will increase, the areas of very-low vegetation coverage will be almost invariant, the changes of vegetation coverage in the whole Shijiazhuang will trend to be stable.
