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 determined 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 investigation 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 forest 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.

摘要:

【目的】研究不同白蜡林分类型下白蜡窄吉丁Agrilus planipennis Fairmaire的地统计学空间格局,为不同白蜡林分类型下白蜡窄吉丁的防治提供科学依据。【方法】在4种不同林分类型下,以白蜡窄吉丁羽化孔为调查指标,分析白蜡窄吉丁种群的数量,研究不同林分类型下白蜡窄吉丁的空间格局。【结果】白蜡窄吉丁在城市绿化林和公路绿化林拟合模型为高斯模型,公园混交林拟合模型为指数模型,行道林中拟合模型为线性模型;在绿化片林、公园混交林、公路绿化林空间分布格局为聚集分布,在行道林空间分布格局为随机分布。【结论】当白蜡窄吉丁的危害达到一定程度时,林分类型并不能改变白蜡窄吉丁的聚集习性,但对所拟合模型的参数和半方差函数值均有影响。城市绿化林和公路绿化林白蜡窄吉丁的危害呈现出由边缘向内部扩散的趋势;公园混交林则根据其种植特点呈现出条带状分布;行道林则呈现随机分布的特点,白蜡窄吉丁的危害特点与林分类型相关。
