Analysis of the spatial distribution pattern of Agrilus planipennis in different forest types
摘要
Abstract
[Objective]To clarify the geostatistical spatial patterns of Agrilus planipennis Fairmaire under different ash types in the hope of providing theoretical guidance for the prevention and control of A.planipennis under different ash types.[Methods]Under four different forest types,the number of A.planipennis was de-termined by using the A.planipennis feathering pores as the investigation index,and the spatial patterns of A.planipennis under different forest types were studied.[Results]The results showed that the fitting model of A.planipennis urban green forest and highway green forest was Gaussian model,the fitting model of park mixed forest was exponential model,and the fitting model in street forest was linear model.The spatial distribution patterns of green forest,park mixed forest and highway green forest were clustered distribution,and the spatial distribution pattern of street forest was random distribution.[Conclusion]Through the geostatistical investiga-tion and analysis of the population of A.planipennis under four forest types,it is shown that when the harm of A.planipennis reaches a certain level,the stand type could not change the aggregation habit of A.planipennis,but it has an impact on the parameters and Variogram function values of the fitted model.The urban green for-est and highway green forest in the contour map reflect the hazard of A.planipennis,which is the trend of A.planipennis spreading from the edge to the inside.The mixed forest in the park shows a strip-like distribution according to its planting characteristics.The street forest shows the characteristics of random distribution.The different hazard characteristics of A.planipennis are related to the forest stand type.关键词
