我们应用1980年全省一类森林资源连续清查固定样地资料,编制了我省航空像片数量化林分蓄积量表。通过判读样片的对照比较,根据像片判读的小班测树因子,查航空像片数量化林分蓄积量表,可以直接获得小班蓄积量。采用这种方法,可以使森林资源调查与伐区调查,进一步使用航测技术,充分发挥我省现有航空照片的作用,并为建立森林经营档案工作创造条件。
We use 1980 a class of forest resources in a continuous inventory of fixed plots of information, compiled our province aeronautical photo quantitative forest stock volume scale. By comparing the samples for comparison, according to the small tree-scanning tree factor for the interpretation of the photos, the quantitative forest inventory scale can be checked and the small-scale stock volume can be directly obtained. This method can make forest resources investigation and cutting area investigation, further use of aerial survey and technology, give full play to the role of the province’s existing aerial photographs, and create conditions for the establishment of forest management files.
