针对林分结构数据,筛选并规范化必要的林分结构因子,对林分内林木将实地坐标转换为屏幕坐标,通过对单株木逐一绘制二维示意图的方式,直观展示林分空间和属性结构。基于GDI+技术,生成空间结构二维示意图反映林分密度、郁闭度、空间分布格局等,生成分布直方图反映林分属性结构分布,实现了湖南攸县黄丰桥林场某林分的结构可视化。结果显示,以可视化手段展示林分结构,比数据表展示更加生动、直观。 更多还原

【Abstract】 Aimed to stand strucutre data,essential stand strucutre factors were screened and standardized.Through transfering the field coordinates into screen coordinates and rendering two-dimensional abridaged general view of every single tree one by one,the spatial and attributive strucutre of the stand was intuitively simulated.Based on GDI+ technology,two-dimensinal spatial sturcuter diagram was generated to reflect stand density,crown density,spatial distribution pattern and so on;while histogram was... 更多还原
