摘要:本文研究了20XX年6月-9月南京地区白背飞虱迁飞路径以及预测其虫源地,通过在农业大学架设的灯诱装置获取的虫量数据以及美国国家大气与海洋局(NOAA)和澳大利亚国家气象局(ABM)共同开发的大气质点轨迹分析平台HYSPLIT对白背飞虱的迁飞轨迹进行回推模拟。并利用Visual Foxpro将得到的多条轨迹终点整合成数据库,再在ArcGIS中得出虫源地概率分布图。通过整理的数据,得出了灯诱虫量高峰,并根据各个高峰时间段的天气状况,水平气流、垂直速度场等信息,分析当时虫量高峰的可能原因。此外,还对虫源地的分布进行了预测。25645 毕业论文关键词:白背飞虱;迁飞路径;轨迹分析
Research on the Immigration of the whitebacked planthoppe Sogatella furcifera(Horváth) in Nanjing in 2016
Abstract:In this paper, we studied the migration path of whitebacked planthopper in Nanjing from June to September in 2016, and predicted the insect land data obtained by the lanterns set up at Nanjing Agricultural University and the data of the National Oceanic and Oceanic Administration (NOAA) ) And the Australian National Meteorological Administration (ABM) jointly developed by the atmospheric particle trajectory analysis platform HYSPLIT on the white back planthopper migration trajectory back to the simulation. And use Visual Foxpro will be the end of the integration of multiple trajectories into a database, and then in ArcGIS to obtain the probability distribution map. Based on the data of the data, the peak of the peak volume of the lamp was obtained, and the possible reasons for the peak of the peak were analyzed according to the weather conditions, horizontal airflow and vertical velocity field. In addition, the distribution of insect species was predicted.
