| 粮食作物面积的准确及时估计对国家粮食政策和宏观经济计划的制订具有重要意义。现有国内外 作物面积的统计调查主要使用空间抽样方法进行。该研究从作物面积空间抽样方法、抽样基础单元（样方 尺寸）优化及样本空间布局的合理布设3个方面，对国内外相关研究进展进行了总结和归纳。在此基础 上，总结了现有作物面积空间抽样研究存在的问题和不足，指出了今后作物面积空间抽样研究的方向和 重点。 |

| Abstract: |
| Accurately estimation of crop area played an important role in formulating food policies and economic program at national scale. Spatial sampling techniques were used to estimate crop area in many countries in the world nowadays. Three aspects including spatial sampling methods for crop area estimation， the optimization of pri- mary sampling unit size（that is sampling-square size） and the regulation of sample spatial distributions were sum- marized in this paper. The problems and shortages occurred in the spatial sampling for crop area estimation were summarized and the development trends were put forward. |
