摘要: 介绍了基于抽样理论和遥感判读技术的森林资源监测的具体过程,分析了不同整群样地个数情况下的森林覆盖率和抽样精度。结果表明,在保持抽取的整群个数不变的情况下,总体抽样精度随整群中小样地个数的增加而提高,但当小样地布设到一定数量时,抽样精度并不能明显提高。本次监测的丹江口库区及上游森林覆盖率为63.62%,抽样精度为95.09%。

关键词: 森林资源监测, 大样地, 整群样地

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
