摘要: 森林发展类型是以森林经营的经济需求和技术可行性相结合的森林经营模式。设计未来森林目标、树种选择和经营措施是森林经营设计中亟待解决的重要技术环节。采用多物种方差比值(VR),χ2检验,Pearson相关系数和Spearman秩相关系数以及Ochiai指数,Dice指数,Jaccard指数和AC联结系数对20个人工林优势种进行种间关联分析。结果表明:种对间的极显著正相关种对数比例较小,群落正处在演替早期阶段;马尾松和红椎、大叶栎的种对间有显著正联结,正联结的种对数较少且程度相对较弱,其余种对无联结或不显著的正、负联结居多。以种间联结为指标来量化树种搭配配置,通过树种结构调整、乡土珍贵树种选择,设计科学的混交种植经营模式,以期实现多样化、高价值和稳定的人工林格局。

Abstract: The interspecific associations of tree species into forest management planning models have become increasingly important in sustainable forest management.Tree selection is one of the important factors of designing forest management plans.In order to study the interspecific associations of tree species affecting the adaptation of plant communities in the process of forest management,we survey 238 sample plots’ data on Masson pine plantation forest in Guangxi Province.A series of techniques including the VR analysis,χ2-test,Pearson correlation coefficient test,Spearman rank correlation coefficient test and Ochiai were used together to analyze the interspecific associations of dominant species.The results indicated that the dominant populations had general positive interspecific association,but the species pairs with significant positive associations were only ten percent of the total 190 species pairs,and most of the species pairs showed weak interspecific association.The interactions among the tree species were generally found to be complementary,yet sometimes contradictory.It was more practical for forest management from the view of multiple interspecific association and tree species selection,instead of a single species.Our study highlights the importance of having a good understanding of the tree selection of target stand as a basis for making decisions regarding forest management.

Key words: plantation, forest development type, interspecific association, tree selection, forest management
