Homogeneous 5\u2003km\u2003\u00d7\u20035\u2003km grid data sets of climate, crop, soil and management parameters were created and grain production in 2005 was simulated. Attempts were made to incorporate SOC into the land evaluation procedure and to quantify the potential effects of SOC deficiency on grain productivity. Results were statistically analysed and the modelling approach was validated. National cropland SOC maps were generated. At the national scale, the cropland SOC content averaged 1.20, 0.58, 0.41, 0.31 and 0.26% for the five 20\u2010cm sections consecutively from the surface downwards. At the regional scale it tended to decline slightly from northeast (1.63%) to southwest (1.11%). On average, 64% of grain yield was lost due to SOC deficiency for the humid provinces and 7% for the arid and sub\u2010arid ones. Soil management options are suggested based on the simulation results.<\/jats:p>","DOI":"10.1111\/j.1475-2743.2007.00136.x","type":"journal-article","created":{"date-parts":[[2008,2,21]],"date-time":"2008-02-21T05:11:33Z","timestamp":1203570693000},"page":"80-91","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Spatial patterns and effects of soil organic carbon on grain productivity assessment in China"],"prefix":"10.1111","volume":"24","author":[{"given":"L.","family":"Ye","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Tang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Verdoodt","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Van Ranst","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,2,21]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.2134\/agronj2003.1408"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2389.1996.tb01386.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1475-2743.1997.tb00550.x"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1475-2743.2002.tb00244.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1475-2743.2002.tb00248.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1475-2743.2004.tb00380.x"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1475-2743.2005.tb00102.x"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.geoderma.2005.05.013"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.geoderma.2006.05.008"},{"volume-title":"The formation of Chinese civilization: an archaeological perspective","year":"2002","author":"Chang K.\u2010C.","key":"e_1_2_6_11_1"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-7061(03)00070-3"},{"volume-title":"Using ArcGIS geostatistical analyst","year":"2001","author":"ESRI.","key":"e_1_2_6_13_1"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.agee.2004.09.003"},{"volume-title":"Guidelines: land evaluation for rainfed agriculture","year":"1984","author":"FAO","key":"e_1_2_6_15_1"},{"volume-title":"Global and national soils and terrain digital databases (SOTER): procedures manual","year":"1995","author":"FAO","key":"e_1_2_6_16_1"},{"volume-title":"Agro\u2010ecological zoning guidelines","year":"1996","author":"FAO","key":"e_1_2_6_17_1"},{"volume-title":"Soil and physiographic database for North and Central Eurasia at 1:5 million scale","year":"1999","author":"FAO","key":"e_1_2_6_18_1"},{"volume-title":"Soil map of the world: revised legend","year":"1990","author":"FAO\u2010UNESCO\u2010ISRIC","key":"e_1_2_6_19_1"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq2001.3031100x"},{"volume-title":"Two long\u2010term instrumental climatic data bases of the People\u2019s Republic of China","year":"1991","author":"IAP & CDIAC","key":"e_1_2_6_21_1"},{"volume-title":"Reference soil profiles of the People\u2019s Republic of China.
