Abstract
The paper analyzed and simulated future tendency of the dynamic evolvement of landscape spatial pattern using GIS technology and Markov chain model in Mengda Nature Reserve of Qinghai Province.Land-use maps of two different periods were used as the basic data,which were inputted,edited and stored in the computer under the supporting of ArcGIS system to form a geospatial database.Transition matrix of land-use was calculated and the condition of land-use of Mengda Nature Reserve was analyzed,with the land-use from 2012 to 2027 were predicted.The results showed that forest land and agricultural land had the largest change.The coverage of forest land increased significantly from 25.58% in 1991 to 46.10% in 2027.Agricultural land decreased from 19.05% in1991 to 1.98% in 2027.关键词
