【目的】分析杉木生态公益林林分空间结构并对其进行评价,为杉木生态公益林空间结构优化措施的制定和其他生态公益林纯林空间结构优化调整措施的制定奠定理论基础。【方法】基于福寿林场不同龄组杉木生态公益林(幼龄林、中龄林、近熟林)18个固定样地的实测数据和9个固定样地的复测数据,采用Voronoi 图确定林木的空间结构单元,进而用混交度、大小比数、角尺度、竞争指数、林层指数和开敞度6个林分空间结构参数分析3个龄组杉木生态公益林间伐补植前后的林分空间结构特征,采用乘除法对各个空间结构参数进行多目标规划,提出林分空间结构评价指数,并参考人工林近自然化改造的目标和技术指标,采用定性...

[Objective]The aim of this study is to provide the theoretical basis for optimizing the stand spatial structure and for developing its ecological,economic and cultural functions by analyzing and evaluating the stand spatial structure of Cunninghamia lanceolata ecological forest.[Method]Neighbor trees of the object one was determined based on the Voronoi diagram,and Stand spatial structure index was calculated based on the measured data in eighteen permanent sample plots and the retest data in nine permanent sample plots of Cunninghamia lanceolata ecological forest of different age groups( youn...
