摘要：森林经营是林业发展的永恒主题,其原理就是道法自然,即遵从自然规律进行既定目标的森林结构调整。森林结构可以帮助我们了解森林的发展历史、现状和生态系统将来的发展方向,已经成为分析和管理森林生态系统的关键因子。森林结构主要通过空间多样性、物种多样性和大小多样性来表征,在很大程度上由相邻木的空间关系所决定。基于相邻木关系的林分空间结构参数角尺度、混交度和大小比数等在国内外关于林分空间结构分析、林木竞争与优势度计算、物种多样性测度以及结构恢复重建与优化调整等研究中被广泛使用,并取得了良好的效果。挖掘空间结构参数新的应用领域以及对结构参数理论体系的进一步完善将是基于相邻木关系的林分空间结构研究亟待解决的首要问题,如何把空间结构的3个方面作为统一整体来分析林分空间结构的特征与变化是目前研究的一个重要方向。未来的研究还将聚焦于变量的三维或二元分布,即变量的"体"、"面"研究,因其可视性将成为现在和未来林学研究的又一重要方向。
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-dimensional or bivariate distribution of variables, studies on which has become another key aspect of current and future forest research due to its visualization.
