| 摘 要： | 以福建闽侯县作为研究区,采用传统抽样(简单随机抽样、系统抽样、分层抽样)、空间抽样(空间随机抽样、空间系统抽样、空间分层抽样)等方法对研究区农作物种植面积进行样本抽选、总体推算及误差估计,结果表明:1 500 m×1 500 m格网为最优抽样单元尺寸,空间分层抽样方法的相对误差为3.86%,变异系数为6.03%,抽样成本为6.03,抽样效率高.与传统抽样方法相比,空间抽样方法显著减少样本容量,节约调查成本.

| Abstract: | Traditional sampling methods of simple random sampling, systematic sampling, stratified sampling, and spatial sampling methods of spatial random sampling, spatial system sampling and spatial stratified sampling were applied to conduct sample extrac-tion, population extrapolation and error estimation in crop acreage in Minhou County. The results showed that spatial stratified sam-pling had the highest sampling efficiency with 1500 m×1500 m square grid as the optimal sampling unit size. And relative error, variation coefficient and sampling cost was 3.86%, 6.03% and 6.03, respectively. Compared to traditional sampling method, spatial sampling method significantly reduced sampling size and saved cost. |
