      abstract = {According to the data of the second national land survey,  the farmland area of China at the end of 2009 was 200  million mu more than the original statistical data. This  raises widespread concern. Analysis is carried out from the  perspective of task, technique, necessities and effect on  China’s grain security of the second national land survey.  Through analysis, it can be deemed that data of the second  national land survey are reliable. It overcomes defects of  traditional survey projects and will be of profound  significance for grasping current situations of farmland  resources in China. Farmers are grain production entities,  while the grain yield survey of farmers is calculated  through sampling survey of per unit area yield and the sown  area. Therefore, the increase in farmland area may indicate  underestimation of the grain yield, and the grain security  risk of China will decline accordingly.},
