摘要：【目的】构建林分内部状态与邻域环境相结合的林分稳定性综合评价方法,为林分经营和可持续管理提供理论依据。【方法】在北京、陕西、甘肃和山西等油松分布较广且具有代表性的区域设置油松林固定样地,使用全站仪对样地内胸高直径大于5 cm的林木进行每木定位,调查林分组成、结构、更新特征和相邻环境类型,采用单位圆法分析林分内部状态特征;基于林分空间结构分析“结构单元”原理,定义邻域环境指数(NEI)。将林分内部状态与邻域环境评价方法整合,提出林分稳定性综合评价方法,并应用该方法评价不同类型油松林的稳定性。【结果】林分内部状态单位圆分析结果表明,甘肃小陇山天然油松林内部状态最好,其次为山西运城中条山天然油松林、陕西铜川玉华宫天然油松林、山西太原东山人工油松林和北京九龙山人工油松林,林分内部状态值(FIS)分别为0.605、0.515、0.479、0.453和0.311;甘肃小陇山天然油松林NEI最高(0.75),其次为陕西铜川玉华宫天然油松林(0.40),山西运城中条山天然油松林和北京九龙山人工油松林NEI均为0.25,山西太原东山人工油松林为负效应(-0.25)。林分稳定性综合评价指数(FCS)天然林高于人工林,其中,甘肃小陇山天然油松林的稳定性最高(0.653),山西太原东山人工油松林的稳定性最差(0.235),其他林分类型的稳定性介于二者之间。【结论】基于林分内部状态与邻域环境的林分稳定性综合评价方法既可表达林分内部状态特征的差异,也可体现邻域环境对林分稳定性的影响,并能够明确反映出天然林林分稳定性高于人工林的一般规律,评价结果更加清晰、直观,为林分稳定性评价提供了一种新思路,对森林可持续经营具有一定指导意义。
【Objective】A comprehensive evaluation method of forest community stability based on stand internal status and neighborhood environment was established to provide enlightenment for the evaluation of stand stability.【Method】Fixed sample plots were set up in Beijing,Shaanxi,Gansu and Shanxi where are the representative areas and widely distributed of Pinus tabulaeformis forest.The total station was used to locate the trees with breast height greater than 5 cm,and the composition,structure,regeneration characteristics and adjacent environment types of the stand were investigated,and the unit circle analysis method was used to analyze the characteristics of stand internal status.Based on the principle of structural unit,the concept of neighborhood environmental index(NEI)was defined.Then,a comprehensive evaluation method of stand stability based on the combination of stand internal state evaluation and NEI was established,and the stability of different types of Pinus tabulaeformis stands was evaluated by this method.【Result】The results of unit circle analysis showed that the internal status of natural Pinus tabulaeformis stands in Xiaolongshan of Gansu Province was the best,followed by the natural stands of Zhongtiao Mountain,Yuncheng of Shanxi Province,Yuhuagong in Tongchuan of Shaanxi Province,Pinus tabulaeformis plantation in Dongshan,Taiyuan of Shanxi Province and Jiulongshan of Beijing,the value of forest internal state(FIS)were 0.605,0.515,0.479,0.453 and 0.311,respectively.The highest NEI was Xiaolongshan natural Pinus tabulaeformis forest in Gansu Province,followed by Yuhuagong natural stand in Tongchuan,Shaanxi Province,with values of 0.75 and 0.40,respectively;the values of NEI of natural Pinus tabulaeformis forest in Zhongtiao Mountain of Shanxi Province and Jiulongshan plantation of Beijing were both 0.25,while that of Taiyuan artificial Pinus tabulaeformis stand was negative,with the value of-0.25.The comprehensive evaluation index(FCS)of stand stability of natural forest was higher than that of artificial forest.The stability of natural forest of Pinus tabulaeformis in Xiaolongshan of Gansu Province is the highest,and that of Dongshan plantation of Taiyuan was the lowest,with FCS values of 0.653 and 0.235,respectively.【Conclusion】The comprehensive evaluation method based on the stand internal status and neighborhood environment could not only express the differences of the state characteristics within the stand,but also reflect the influences of the neighborhood environments on the stability,and could clearly reflect the general rule that the stability of natural forest is higher than that of artificial forest,and the evaluation results are more clear and intuitive,which provides a new idea for the stability evaluation of forest stand and has a certain guiding significance for sustainable forest management.
