摘要 介绍一种新的不等概率抽样技术——适应性群团抽样(ACS)。概略地介绍了其概念、特点、基本估计方法和研究概况。举例比较适应性群团抽样技术和随机抽样技术在稀疏群团植被调查中的精度和效率。 A new inequality probability sampling----adaptive cluster sampling (ACS) is presented, which includes the conception, characteristics, the two basic estimators of ACS and some reviews. The precision and efficiency between ACS and simple random sampling (SRS) are compared based on the case of trees of rare and clumped characteristics.
