Abstract：

Time Series of Land Ecosystem Classification Dataset of China in Five Yearly Steps is consisted of 7 land ecosystem types of China. They are: farmland ecosystem, forest ecosystem, grassland ecosystem, wetland ecosystem, resident ecosystem, desert ecosystem and others. The raster data is in 100 meters pixels. The time series of data products indicate that the wetland changes of China are not very much during the last 25 years, the resident including urban ecosystem increased from 1.65%（1990）to 2.09%（2010）；the farmland ecosystem increased from 18.65%（1990）to 18.80%（2010）. However, grassland ecosystem decreased from 31.98%（1990）down to 31.56%（2010）and forest ecosystem decreased from 23.74% down to 23.64%（2010）.The fluctuating fugues are shown for each ecosystems during the 25 years.Browse
