Summary:Due to the increasing man-made activities,the vegetation landscape in the rapidly urbanized areas has changed dramatically.Based on the theory of landscape ecology and the evaluation method of ecosystem service function,this study took the vegetation of Shenzhen City as the research object,and used TM image as the main data source in 1985,1995,2005 and from Vol.4 of 2015 with the support of remote sensing and GIS technology to analyze the variation of vegetation landscape fragmentation and its ecological change.The results showed that the vegetation landscape fragmentation in Shenzhen City was significant in the past 30 years,and the vegetation landscape was the main characteristic in the fluctuation trend.The change trajectory of the vegetation landscape was the main focus,and the woodland land area was the largest land for construction.The fragmentation of vegetation landscape reduced the overall value of ecosystem services and hindered the function of life support systems.
