摘要
对比分析了概率抽样和空间抽样理论和方法,用农业抽样调查实例证明了对于存在空间相关的空间抽样问题,采用空间统计理论和方法确定的抽样策略才是适宜和高效的。同时从理论的角度验证了分层抽样和系统抽样是抽样调查中行之有效的方法。
The theories and methods were compared between probability sampling and spatial sampling, and it was proved by using several agricultural sampling survey cases that the sampling strategies established by spatial statistical theories and methods are suitable and efficient when there are spatial sampling problems with spatial autocorrelation.It was also theoretically verified that systematic sampling and stratified sampling are feasible methods in spatial sampling survey.
