中德合作项目造林质量与数量调查监测新方法——样圆抽样调查法

摘要

Investigation and monitoring after afforestation,like checking the survival rate of trees,monitoring afforestation quality and analyzing the reasons of success or failure are very important for assessing afforestation effect,improving afforestation technologies and improving the effectiveness and level of afforestation engineering.This paper introduced the circular sampling investigation method,a new investigation and monitoring method on forestation quantity and quality applied in Sino-German cooperation forestation project,and analyzed the advantages and disadvantages of the method.%造林后的调查与监测对于考核造林效果,检查造林成活率,监测造林质量,分析成败原因,改进造林技术,提高造林工程的成效与水平都具有十分重要的作用。本文结合安塞县中德合作造林工程的实践,介绍了造林质量与数量调查监测新方法——样圆抽样调查法,分析了样圆抽样调查监测法的优缺点,供各地在造林工程调查监测工作中参考应用。
