基于遥感的福建闽侯丘陵区农作物种植面积空间抽样方法
Spatial sampling method for crop acreage based on remote sensing in hilly area in Minhou County, Fujian Province
摘要
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.关键词
