摘要/Abstract

摘要： 对安徽国外松衰退病与其环境和林分因素关系的调查研究和数量化分析表明,在气候、土壤、林分、其它病虫害等4类因素18个变量因子中,有10个因子对病情有较大的贡献,成为该病发生的主要致病因素.它们是树龄、林分密度、割脂、降雨量、温度、粘性土、石砾土、土层瘠薄、积水、病虫危害.其中病情与土层深度、降雨量呈负相关;与其它因素均呈正相关.以此建立病情线形回归预测模型,根据这一模型,可以预测任一给定条件下的林分国外松衰退病可能发生的水平.此外,依据各致病因素在病害发生发展过程中的作用大小和时间顺序,绘制出国外松衰退病的螺旋图,为该类病原复杂的病害形象描述和定量分析作出了探讨.

Abstract: The relationship between decline disease of exotic pines(Pinus taeda and P.eliottii)plantations in Anhui Province and forest stand status and environmental factors was quantitatively analyzed.Among 18 variable factors from 4 types of factors(climate,soil,stand status,and other diseases and insect pests),10 factors contributed greatly to the state of illness.These were tree age,stand density,resin tapping,rainfall,temperature,clay soil,stone soil,soil depth,water logging,and other diseases and insect pests.Of them soil depth and rainfall negatively,and others positively related with the severity of disease.Accordingly,a linear multiple regression model was derived,which might predict the developmental level of decline disease at any given conditions of exotic pine plantation.In addition,the spiral chart of decline disease was mapped based on the action size and time order of various nosogenetic factors during the incidence of decline disease,which was used to visually describe and quantitatively analyze the disease with complicated causes.

Key words: Exotic pines, Decline diseases, Environmental condition, Forest stand factors, Quantitative analysis, Spiral chart, land use, loess hilly region, vertical variation, soil water storage characteristics, soil moisture, grey relational analysis
