摘　　要：以抽样理论为基础,以全国森林资源宏观监测9个省的遥感判读结果为依据,对比分析了群团样地判读和图斑区划判读的森林覆盖率、森林面积、正判率、抽样精度和差异原因。结果表明:群团样地判读和图斑区划判读2种方法监测森林资源都能取得预期效果;通过U检验,2种方法得到的森林覆盖率没有明显差异。但群团样地判读质量相对易控制、工作量较小、工作效率更高。According to sampling theory,based on the remote sensing monitoring results of 9 provinces,a comparison of forest coverage rate,forest area,correct-judgement rate,sampling precision and diffidence reason was done between zoning interpretation and point interpretation by remote sensing. Both zoning interpretation and point interpretation get anticipated result. U Test results show that both of forest coverage rates have no clear differences. but point interpretation has the advantages of less workload and higher efficiency.
