摘　　要：以往的林分空间结构优化大多是根据1期的林分调查数据,采用林空结构3指标(角尺度、混交度、大小比数)来反映空间结构状况。研究利用帽儿山实验林场固定样地2期调查数据及林木价格数据,采用林分空间结构指数和林分空间距离指数对固定样地的各主要目标树种进行空间格局分析,并结合林木的价值增长率指标对采伐的林木进行最优化控制,以实现天然次生林合理的经营。In the past,the spatial structure optimization of forest stands was mostly based on Phase I data of forest survey,and three indicators of forest space structure(angle scale,mixing degree,size ratio)were used to reflect the spatial structure.Based on the two-stage investigation data and forest price data of Maoershan Experimental Forest Farm,the spatial structure index and spatial distance index of forest stand were used to analyze the spatial pattern of the main target tree species in the fixed sample plot,and the optimal control of the harvested trees was carried out combined with the value growth rate index of trees,so as to realize the reasonable management of natural secondary forest.
