The loess-derived soils are fertile but extremely susceptible to erosion. Soil erosion in the study area is much higher than that in the southern part of the Loess Plateau. The climate belongs to transition zone of warm temperate semi-humid to semi-arid, which is dry and windy in spring, hot and rainy in summer, and dry and cold in winter. The mean annual temperature is 8.8 \u00b0C. The minimum and maximum temperatures are \u221223.6 \u00b0C in February and 36.8 \u00b0C in July. The frost-free period is 157 days. The mean annual precipitation is 505 mm, 70% of which falls between July and September in the form of short heavy storm. The soil is silt loam with the contents of sand, silt, and clay being 24%, 65%, and 11%. Ansai station mainly focus on vegetation rehabilitation, monitoring and assessment of rehabilitation, and  monitoring in watershed.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1973,"yearClosed":null,"relatedSites":null,"siteName":"Ansai
