It joined the Chinese Ecosystem Research Network (CERN) organized by CAS in 1991 and the National Ecosystem Research Network of China (CNERN) in 2005 by the Ministry of Science and Technology of the People\u2019s Republic of China.\r\n\r\nThe station located in Wangdong Village, Hongjia town, Changwu County, Shaanxi Province, 200 km away from Xi\u2019an city. Its location is E107\u00b041\u2032 and N35\u00b012\u2032, south of the Loess Plateau.\r\n\r\nIt belongs to the warm temperate semi-humid continental monsoon climate. Mean annual precipitation is 580mm and temperature 9.1\u2103, frost-free day 171. The elevation is about 1200 m and the depth of ground water is 50-80m. Main crops are winter wheat, spring maize, potato, sorghum, millet, beans and so on. The zonal soil is called Heilu soil with a parent material of clay loam Malan loess paleosol soil with an average depth in excess of 100m that were deposited during the Quaternary period. It belongs to the high table land - gully region, and a typical rain-fed agricultural area on the Loess Plateau.\r\n\r\nWangdong small watershed, which the station located in, is 6.3km2. Three landform types are high table land, slop land called \u201cLiang\u201d and valley, which occupy the total area of watershed with 35%, 35.6% and 29.4%, respectively. The soil is deep and has good physical properties, like reservoir, support the agro-ecological system.\r\n","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1984,"yearClosed":null,"relatedSites":null,"siteName":"Changwu
