基于ArcGIS的森林资源清查样木位置图绘制研究

Study on Drawing of Sample Tree Location Map Based on GIS in Forest Resources Inventory

在森林资源清查中,样木位置图是样地的调查成果之一,不仅针对样地内每株样木的位置进行标示,也是复位的重要依据。良好的样木位置图有助于样地与样木的复位与调查。利用计算机软件Excel 2013和ArcGIS 10.2进行样木位置的数据管理与样木位置图的绘制,实现间伐前后样木位置图的计算机可视化,提高了样木调查的效率与定位的精度。

The sample tree location map was one of the survey results of the sample plot in forest resources inventory.It was not only the location of each sample tree in the sample plot,but also an important basis for resetting.A good sample location map was helpful to the resetting and investigation of sample plots and samples.The data of sample tree location was managed and the sample tree location map was drawn by using software Excel 2013 and ArcGIS 10.2.The visualization of sample tree position map before and after improvement cutting was realized,and the efficiency of sample tree investigation and positioning accuracy were also improved.
