Based on the MODIS NDVI data and Landsat TM/ETM data of 2002 and 2012,this paper extracts the planting area of winter wheat-summer maize,single spring maize,cotton and forest/fruit trees,vegetable and paddy,and made the agricultural land use map of the North China Plain (NCP).Agricultural land use area accounted for 63.32％ compared to the total area of the NCP in 2002.And it increased to 65.66％ in 2012,which mainly caused by the vegetables and forest/fruit trees increasing.Planting areas of winter wheat-summer maize,cotton,single spring maize,forest/fruit trees,vegetables and paddy were 5031.21 x103,865.90x103,1226.10×103,1271.17×103,648.02×103,216.51×103 ha in 2012.Rank of changes was:vegetables (+45％) ＞ forest/fruit trees (+27.4％) ＞ paddy (-23.7％) ＞ cotton (-20.4％) ＞ single spring maize (+17.3％) ＞ winter wheat-summer maize (-0.6％).In developed region like Beijing and Tianjin,planting area of crops with high economic benefit (such as fruit trees and vegetables) increased significantly.Government policies for groundwater protection caused obvious decline of winter wheat cultivation in Hebei Province.Cotton planting in Shandong Province decreased more than 200,000 ha during 2002-2012.The data products will be published in the website:http://hydro.sjziam.ac.cn/Default.aspx.To clarify the agricultural land use in the NCP will be very helpful for the regional agricultural water consumption research,which is the serious problem in the NCP.
