Land Use And Landscape Pattern Change Research Of The Site Of Xanadu In Recent 30 Years

In April 27,2012,the Site of Xanadu has become the thirtieth world cultural heritage in China,and become the first world cultural heritage in Inner Mongolia Autonomous Region.The Site of Xanadu is one of the soul of the prairie culture. In recent years, human disturbance and environmental degradation has become a serious threat to the protection of the Site of Xanadu. Therefore, this paper takes the protection area of the Site of Xanadu as the research scope, uses RS、GIS technology and landscape pattern analysis software,combine with field survey data, analysis the land use and landscape pattern changes of the Site of Xanadu in recent 30 years, and understand the trend of this change in order to put forward relevant suggestions for further protection in the Site of Xanadu. The main results are as follows:1、In 1984 to 2013, Grassland is the main land use types;the farmland has a largest area reduction,and it is mainly conversion into grassland and Woodland; The woodland has a largest area increasing,and it is mainly The woodland has a largest area increasing,and it is mainly transformed from farmland and grassland. In the secondary land use types, moderate coverage grasslands has the largest area, the plain dry land has a largest area reduction, shrub forest has a largest area increasing.2、In 1984 to 2013, The single land use dynamic degree change rate of woodland、 grassland、water wetland、construction land,showed an increasing trend, woodlands increasing rate is the highest among them; In 2000 to 2005, the comprehensive dynamic degree of land use is the highest.3、The integrity of the landscape is highest in 2000,and the landscape structure is the most complex in 2005, landscape changes occurred mainly among 2000 to 2005,the landscape pattern is more and more diversification and fragmentation.
