摘　　要：【目的】明确赤松枯梢病与乔木层、灌木层和草本层植物物种的关联性,筛选与赤松枯梢病呈显著关联的植物物种,为通过林分内植物物种组成改造来调控赤松枯梢病提供技术支持。【方法】以昆嵛山赤松天然次生林群落为研究对象,设置120块临时样地进行乔木层、灌木层和草本层植物物种以及赤松枯梢病病情调查,计算各植物物种重要值,应用方差比率法检验赤松枯梢病病情指数与植物物种总体关联性,利用Pearson相关分析和Spearman秩相关分析定量判定病情-植物物种间的关联性。【结果】赤松枯梢病病情与乔灌草植物物种总体关联性均为显著正关联(P<0.05)。Pearson相关性分析发现赤松枯梢病病情与乔木层赤松和黑松,灌木层胡枝子以及草本层白茅、败酱、宽蕊地榆、木防己、茜草、射干、狭叶珍珠菜、野菊、野青茅和紫花地丁呈显著或极显著正关联(P<0.05);与乔木层麻栎、山槐、栓皮栎和盐肤木,灌木层大花溲疏和葎叶蛇葡萄,以及草本层灯心草、鹅绒藤、毛秆野古草、香茶菜、杏叶沙参呈显著或极显著负关联(P<0.05)。Spearman秩相关分析发现赤松枯梢病与乔木层赤松和黑松、灌木层胡枝子和紫穗槐以及草本层白茅、败酱、桔梗、宽蕊地榆、木防己、茜草、射干、狭叶珍珠菜、野菊、野青茅和紫花地丁呈显著或极显著正关联(P<0.05);与乔木层麻栎、山槐、栓皮栎、水榆花楸和盐肤木,灌木层大果榆、大花溲疏、葎叶蛇葡萄、小花扁担杆和郁李以及草本层灯心草、鹅绒藤、毛秆野古草、香茶菜、杏叶沙参和鸭跖草为显著或极显著负关联(P<0.05)。2种分析方法结果具有一致性,也存在一定差异,Spearman秩相关分析结果较Pearson相关分析结果更为灵敏。【结论】昆嵛山赤松天然次生林群落中的植物物种与赤松枯梢病形成了稳定的共存状态,其中13种植物物种与赤松【Objective】This study aims to clarify the correlation between shoot blight of Pinus densiflora and plant species in the layer of arbor,shrub and herb,and screen plant species significantly correlated with shoot blight of P.densiflora,so as to provide technical support for controlling shoot blight of P.densiflora through the transformation of plant species composition in the stand.【Method】A total of 120 temporary sample plots were set up in the natural secondary forest community of Japanese red pine in Kunyu Mountains to investigate the plant species of arbors,shrubs,herbs and the disease index of shoot blight of P.densiflora.Then the important values of plant species were calculated,and the variance ratio analysis was used to test the correlation between plant species and shoot blight of P.densiflora,and Pearson correlation analysis and Spearman rank correlation analysis were used to quantitatively determine the correlation between disease and plant species.【Result】There was a significantly positive correlation between the disease index of P.densiflora shoot blight and the overall association of the neighboring arbors,shrubs and herbs(P<0.05).Pearson correlation analysis showed that the disease index of P.densiflora shoot blight was significantly or extremely significantly positively correlated with arbors—P.densiflora and P.thunbergii,shrub—Lespedeza bicolor and herbs—Imperata cylindrica,Patrinia scabiosifolia,Sanguisorba applanata,Cocculus orbiculatus,Rubia cordifolia,Belamcanda chinensis,Lysimachia pentapetala,Chrysanthemum indicum,Deyeuxia pyramidalis and Viola philippica(P<0.05).Whereas there was a significant or extremely significant negative correlation with arbors—Quercus acutissima,Albizia kalkora,Quercus variabilis and Rhus chinensis,shrubs—Deutzia grandiflora and Ampelopsis humulifolia,herbs—Juncus effusus,Arundinella hirta and Adenophora petiolata subsp.hunanensis(P<0.05).Spearman rank correlation analysis found that the disease of P.densiflora shoot blight was significantly or
