【摘要】：闡述了全國森林資源宏觀監(jiān)測的抽樣框架設(shè)計及群團抽樣設(shè)計;研究提出了針對圖斑區(qū)劃判讀和群團樣地判讀2種方案的抽樣估計方法,包括系統(tǒng)抽樣、整群抽樣和兩階抽樣,其中整群抽樣更適合于圖斑區(qū)劃判讀,而兩階抽樣更適合于群團樣地判讀;9個省的抽樣估計結(jié)果對比表明,不等群團的整群抽樣估計方法對圖斑區(qū)劃判讀和群團樣地判讀都是合適的。
[Abstract]:The sampling frame design and cluster sampling design for the macro-monitoring of forest resources in China were expounded. In this paper, two methods of sampling estimation are proposed, including systematic sampling, cluster sampling and two-stage sampling, in which cluster sampling is more suitable for map division interpretation. The two-stage sampling is more suitable for the interpretation of cluster plots. The comparison of sampling estimation results in 9 provinces shows that the cluster sampling estimation method of unequal clusters is suitable for the interpretation of map pattern zoning and cluster plot interpretation.
