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。

Abstract:

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.

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