Abstract

Abstract: According to sampling theory,based on the remote sensing monitoring,this paper describes a specific process of forest resources monitoring,and a comparison of forest coverage rate and sampling precision was done by different cluster size.The results show that the bigger the cluster size is the higher the sampling precision is.But sampling precision did not get higher when the cluster size achieved a certain number.The forest coverage rate in Danjiangkou reservoir area and upstream was 63.62%,sampling precision is 95.09%.

Key words: forest resources monitoring, large plot, cluster plot
