Abstract

Based on the theory of stratified cluster sampling,and the actual overseas cases ,this paper describes a specific process of stratified cluster sampling,and analyzes overall accuracy.The results show that stratified cluster sampling accuracy is improved by 7% compared with cluster sampling accuracy in the same sample.

Key words： forest resources survey; stratified sampling; cluster sampling
