The frame adopted for this survey was the telephone listings for the Taiwan Area. In order to avoid being unable to select those residences with unlisted telephone numbers, we first took a systematic random sample of telephone numbers, and then replaced the last digit with a random number. Respondents were chosen from within the selected household according to a set intra-household sampling procedure. The target for this survey was 1200 successful interviews.
本研究以台湾地区住宅电话簿作为抽样的母体清册,为避免未在电话号码簿上登记的用户无法被抽中进行访问的情形,抽样时首先依系统抽样的原则抽出某一电话号码,再以随机乱数取代此号码的尾数,作为访问的样本户,访问时再由访员依户中抽样的原则,抽出应受访的对象进行访问。

Firstly,the sampling design has great impact on the accuracy of remote sensing classification.There exists great randomicity on the result of points and cluster sample verification on the different Sampling design.On the same sampling design,the stability of point sample verification is higher than that of Cluster sample verification.Secondly,the average accuracy of different sampling designs of multi-point and multi-cluster sample verification can reflect the accuracy characteristic.During the course of point sample verification,stratified sampling's error is lower than others'.During the course of cluster sample verification,systematic sampling and stratified sampling's accuracy are prior to simple random sampling's.
研究结果表明:(1)抽样方式对遥感分类精度评价结果的影响是客观存在的,不同抽样方式下的点样本和群样本检验结果都存在一定的随机性,但同一种抽样方式下,点样本检验精度评估结果的波动幅度小于群样本检验,稳定性比群样本检验要好;(2)不同抽样方式下的多次点样本和群样本检验的平均精度检验结果基本上都能够反映分类图像的精度特征,其中,点样本检验中,分层随机抽样点样本检验效果较好;群样本检验中,系统抽样群样本检验和分层随机抽样群样本检验的效果优于简单随机抽样群样本检验。
