Soil erosion is the displacement of the upper layer of soil caused by the dynamic activity of erosive agents. Four surveys have been conducted about soil erosion in China since 1985, and the provincial summaries of soil erosion were published in various sources (mainly in printed version). This dataset was the result of compilation and preliminary analysis about these publications, which was organized in 2 erosion types (water erosion, wind erosion), 5 erosion severity grades ( Light, Moderate, Intense, Extremely Intense, and Severe ), 4 epochs (1985, 1995, 2000, 2011), and 31 provinces. The preliminary analysis showed that, in national level, the ratio of water erosion and wind erosion in 2011 was 44:56, and the percentage of 5 erosion severity grades were Light 47%, Moderate 19%, Intense 13%, Extremely Intense 10%, and Severe 11%. During 1985-2011, soil erosion in China as a whole has been in decline, from 3.66 million km²(1985), through 3.55 million km² (1995) and 3.56 million km² (2000), to 2.95 million km²(2011), corresponding to a percentage decline from 38.53% in 1985 to 31.04% in 2011. In terms of erosion types, water erosion experienced a steady decrease during 1985-2011, yet wind erosion area was volatile from epoch to epoch, although also demonstrating a general declining pattern. In provincial level during 1985-2011, the first three provinces with the largest drop in percentage of eroded land were Ningxia (75.04% - 37.87%), Shaanxi (64.15%-35.33%), and Henan(39.26%-14.23%. Meanwhile, four provinces had a increase in soil erosion: Guangxi(4.71%-21.35%), Guangdong(6.4% - 11.98%),Hainan(1.33%-3.2%), and Jilin(20.89% - 25.28). The dataset is composed of 6 tables in 1 Excel files with data size of 44.5 KB.
