摘要: [目的] 研究广西兴安地区中稻田白背飞虱空间分布格局,为提高其监测预警及有效防控提供依据。[方法] 采用GS+软件建立不同时期中稻田白背飞虱若虫种群密度的半方差函数模型,并利用ArcGIS软件普通克立格插值法对白背飞虱若虫种群密度进行插值和模拟。[结果] 广西兴安地区中稻田白背飞虱若虫种群密度从7月初中稻分蘖期到9月上旬中稻收获,随时间呈现双峰型。田间分布格局随时间表现出聚集分布-随机分布-聚集布集-随机分布的趋势。在呈现聚集分布的各次调查中,白背飞虱若虫空间相关范围为7.32~36.93m,结构性强度为50.5%~97.4%,具有较强的空间相关性。[结论] 白背飞虱若虫种群具有空间异质性和时间异质性。

Abstract: [Objective] Spatial distributions of white-backed planthopper (WBPH) nymphs were studied to provide a basis for early warning and effective control.[Method] The semivariograms models of WBPH nymphs in different rice growing stages in the middle season rice field were constructed by using software GS+,and simulation charts of the WBPH nymphs at each stage were created by using software ArcGIS with Kriging interpolation.[Results] From rice tillering stage to the rice harvest,the population density of WBPH nymphs changed with time and showed double peak type.The spatial distribution of WBPH nymphs were aggregation distribution-random distribution-aggregation distribution-random distribution with time changed.The space-related area of WBPH nymphs in the investigation which showed aggregation distribution were 7.32-36.93 m,the structure intensity were 50.5%-97.4%.The spatial correlation of WBPH nymphs was strongly dependent.[Conclusion] The WBPH nymphs population had spatial and temporal heterogeneity.
