In this paper, aerial images and satellite images of Bitahai watershed from 5 different periods from 1955 to 2011 were used to conduct a landscape dynamic analysis. Area transition matrixes of these periods were calculated. On this basis, compatibility of Morkov model was proven, identities of the change mode of the periods were tested, and analysis about change trend during the periods were made.Conversion-in rate, conversion-out rate and preserving ratio of landscape elements were introduced to describe the detailed change process. It was found that natural succession was the main landscape change process, human disturbance came along with tourism development. More sophisticated research under smaller scale was suggested to support targeted protective measures. |
