Forestry, grass land, water area, arid land, paddy field and building lot were classified in maps. Overall accuracy values of three-phase land use vector diagram are 96.89%, 98.55% and 93.17%, and kappa coefficient values are 0.95, 0.97 and 0.93. Maps in Fig 11 were generated by ArcGIS 10.2 and ENVI 5.2 and the URL links of software are http://www.esri.com/ of both. Three-phase TM images of 1990, 2000 and 2010 from free download data of U.S. Geological Survey (http://glovis.usgs.gov/) were used.
