| 摘 要： | 抽样检验是测绘成果质量检验的基本方法，抽样方案与被检成果质量水平的匹配程度直接决定抽样检验的效果。针对抽样方案的适用性和有效性评价问题，提出了计数型抽样方案的质量不确定性区间（quality uncertainty interval,QUI）的概念，并以给定概率水平条件下的QUI的长度评价抽样方案的适用性和有效性，以比较客观地反映抽样方案的两类风险程度。对4个典型测绘成果质量检验的抽样方案和6个仿真抽样方案进行数值计算和分析，验证了该方法的正确性和合理性。结果显示，该方法不仅适用于测绘地理数据的统计分析和成果质量检验，还可用于各种计数型抽样方案设计和两类风险控制。

| Abstract: | Objectives Sampling inspection is a fundamental approach in quality management and controlling of surveying and mapping achievements. The matching degree between the sampling scheme and the quality level of the tested results directly affects the result of quality inspection. Methods To evaluate the suitability and validity of sampling schemes, we construct the concept of quality uncertainty interval (QUI) for counting sampling schemes. The suitability and validity of the sampling schemes are evaluated by the length of QUI at a given probability level, so as to objectively reflect the two types of risk degrees of the sampling schemes. Results The correctness and rationality of the method are verified by numerical calculation and analysis of four typical sampling schemes for quality inspection of surveying and mapping results and six simulated sampling schemes. Conclusions The results show that the proposed method is not only suitable for statistical analysis of surveying and mapping data and quality inspection of results, but also for various count-based sampling scheme designs and two types of risk control. |
