运用高精度南方NTS-960R型免棱镜全站仪，结合多边形样地森林资源调查方法，对赤峰市旺业甸林场200块标准地进行调查。选取4块有代表性的标准地，对标准地每木进行胸径和树高测量，将多边形样地法数据与样地每木检尺数据比较分析。结果表明：多边形样地法调查面积和调查株数不固定，每个样地的面积在0．005～0．015 hm2，树木6～9棵，外业工作量相对于标准样地法小；多边形样地法在天然林和混交林中的精度低，在单层林和人工林中的精度高；随着样地数量增加，精度逐渐提高，在天然林中，精度可达到85％以上，可适用于二类调查；在人工林中，精度可达到95％以上，可适用于三类调查。将多边形样地进行固定，可实时对林分生长量进行监测。

By choosing four representative plots from Wangyedian Forest Farm , Chifeng City, we measured the DBH and height of each tree with a total of 200 standard plots and collecting the data in the field surveying by using high-precision NP total station NTS-960R.We compared and analyzed the data collected from polygon plot , and the polygon plot method was not fixed about survey area and the number of trees .The area of every sample plot was about 0.005-0.015 ha, the numbers were about 6-9, and the workload in the field surveying was much more less than standard sample. The precision stability of separate polygon method was low in the natural forest and mixed forest , while it was high in the regular forest and planta-tion.With the increasing of sample plots , the precision stability greatly improved and it would be able to reach more than 85%in the natural forest and plantation , and could be applicable in the second class survey .The precision would be up to 95%in the plantation and could be applicable in the third class survey .Making the polygon sample plots fixed could moni-tor the stand increment in real time .
