| 摘 要： | 简述了在内蒙古两个林业局的森林二类调查中用ＴＭ影象代替航片进行区划、调绘、定位和面积量算、测树因子估测的试验方法和结果。试验与生产同步展开，进行了对照，数据表明，用１：５万ＴＭ影象代替航片进行区划、调绘、求积，其精度均能满足规程要求，但在测树因子估测方面尚不理想。

| Abstract: | This paper introduced the experimental method and results of using TM data instead of aerial photo to do the forest division.Sketching on the spot,calulation of area and estimation of stand factors in subcompartment.The results shows that using 1:50 000 TM image instead of aerial photo to do these items mentioned above can fully meet the need of the operation rules in forest management inventory,except the estimation of stand factors in subcompartment.Both the laboratory work and traditional inventory were carried out at the same time,in two Forestry Bureaus in Inner Mongolia. |
