Vegetation Landscape Changes In Changbai Mountain By Remote Sensing

The main purpose of this study is to research the performances of the possible artificial interference in the Changbai Mountain vegetation dynamic changes. Dynamic monitoring of vegetation in Changbai Mountain area is very necessary to the measurement, evaluation and research of ecological integrity. Technical support of this research are remote sensing image processing technology and geographical information system technology, the total time span is twenty years. On interpretation of the remote sensing images of1987,1999,2007, on this basis, the parameters of landscape pattern changes were calculated, and, causes were analyzed. Research shows that, from1987to2007in the Changbai Mountain area, the vegetation landscape pattern changes significantly. In twenty years the vegetation area increased in general, not in the time axis showed increasing trend, but different periods of fluctuation; landscape patch number totally increased, the landscape type had significant and complex transfer.
