中国农产量调查中几种可行的PPS系统抽样设计

Feasible Systematic PPS Sampling Designs for the China Crops Survey

PPS系统抽样设计是国际上比较流行的设计,它在实践中有着广泛的应用。我国农产量调查采用的是对称等距抽样设计,它实际上可理解为是一种变形的PPS系统抽样设计,使用的是以播种面积作为辅助变量。文章给出了几种可行的PPS系统抽样设计,辅助变量分别取为农户数、播种面积、耕地面积、切块数,并对这几种抽样设计进行了应用分析。

Systematic PPS sampling design is a kind of popular design in the world that is widely applied in practice. The symmetric and systematic design has been adopted in China Crops Survey, and it is a kind of (systematic) PPS sampling design with auxiliary variable, area of crops planted. This paper presents several (feasible) systematic PPS sampling designs, with household, area of crops planted, area of cultivated land and number of segment are chosen as auxiliary variables. Some discussion for the application of these sampling (designs) are also presented.
