摘要: 对畜禽存栏量的调查是农业统计调查的重要内容之一,其统计调查方法主要是抽样调查。本研究旨在通过实例抽样调查,拟出合适的抽样方法对全国的基础母牛存栏量进行调查估计。采用二阶PPS(sampling with probability proportional to size)抽样、分层等比例抽样、分层二阶典型抽样对内蒙古敖汉旗肉牛存栏量进行调查,比较3种方法的准确度。结果表明, 在此3种方法10%的样本量下进行比较时,3种抽样方法按相对误差大小顺序排列为:分层二阶典型抽样<分层等比例抽样<二阶PPS抽样,其相对误差分层二阶典型抽样比分层等比例抽样、二阶PPS抽样分别小60.38%、92.83%;置信区间按大小顺序排列为:分层二阶典型抽样<分层等比例抽样<二阶PPS抽样。总体而言,分层二阶典型抽样的准确度相对较高,相对误差最小,仅为0.0412。故在实际应用当中,分层二阶典型抽样目前较为适用。

Abstract: A survey on farm animals storage was an important part of agricultural survey, the mainly survey method was sampling. The objective of the study was to select a suitable sampling method based on an example to estimate the nationwide cow storage. Second-order PPS(sampling with probability proportional to size) sampling,the stratified proportion sampling and the stratified second-order typical sampling were adopted in the survey on beef cattle storage in the Aohan county, Inner Mongolia, compared the accuracies given by the three methods. The results showed that under the optimal sample size for each of the three methods,the order of the three methods according to the relative error was: the stratified second-order typical sampling<the stratified proportion sampling<second-order PPS sampling, and the relative error of the stratified second-order typical sampling was less than the stratified proportion sampling and second-order PPS sampling to 60.38 and 92.83 percent respectively, while the order of the confidence interval was:the stratified second-order typical sampling<the stratified proportion sampling <second-order PPS sampling. Overall, the stratified second-order typical sampling gave the highest accuracy,and the relative error was the smallest. Therefore, in actual application,the stratified second-order typical sampling is the most applicable.

Key words: beef cattle storage; stratified sampling; second-order sampling; typical sampling
