Abstract: Stand spatial structure indicators are defined as indexes to describe the features of forest spatial structure,which not only plays an important role in analyzing and controlling the forest structure and function relationship,but also is the focus and difficult point in the research of stand spatial structure.The article was based on the analysis of the research status of stand spatial structure unit,summed up the research trends of stand spatial structure indicators from the spatial isolation of trees,tree competition,tree spatial pattern,stand vertical structure.Currently,the two methods used to calculate the forest stand spatial structure index by using 4 or ordinary Voronoi diagram to constitute a space structural unit have some disadantages.But these disadantages can be offset when we generate a weighted Voronoi diagram with the diameter at breast height,tree height,and crown as comprehensive weight.Meanwhile,using a single stand spatial structure parameters to analyze a feature of the forest stand spatial structure or overall characteristics of a tree cannot express trees' microstructur if they have certain common characteristics.So it will be a future trend in stand spatial structure analysis,which will display stand spatial structure in three dimnsional space by using the joint probability distribution of the space structure parameters available together.
