Forest management is a perpetual theme of forestry development, whose principle is following the law of nature, which, in other words, is abiding by the regular pattern of nature to achieve structural adjustment of forest given a certain objective. Forest structure helps us understand the history of forest development, its current condition and the future development of ecosystem. This is crucial to analyzing and managing forest ecosystem. The structure of forest characterized by the diversity of spatial position, species and dimension, to a greater degree, depends on the spatial relationship of neighborhood trees. Stand spatial structure parameters based on the relationship of neighborhood trees like uniform angle index, mingling and dominance are widely used both internationally and domestically in the studies of stand spatial structure analysis, competition among trees, calculation of dominance, species diversity measurement and structure recovery and reconstruction as well as optimization adjustment. This has yielded positive results. How to integrate the three aspects of spatial structure into one entity for the purpose of analyzing the features and changes of stand spatial structure points to an important direction of future research. Future research will focus on the 3鄄dimensional or bivariate distribution of variables, studies on which has become another key aspect of current and future forest research due to its visualization.
