1 引言松毛虫小班虫情图形处理系统能够灵活、快速地绘制县(市)、乡(镇)、场及其“感兴趣”区域内的小班图形,具有很大的随意性和变倍率放大功能。它不仅能够准确、直观地把油松林分布、虫情变动实况、虫灾等级以及设计防治区城描绘在图上,而且绘制的图形可指导虫情调查、防虫设计,从而成为飞机治虫时的领航用图。它既可独立运用,又可与已开发出的“松毛虫小班虫情统计管理系统”、“松毛虫防治对策计算机辅助设计系统”、“松毛虫发生期、发生量预测系统”联合运行,在一定程度上拓展
1 Introduction Moth caterpillar insects graphics processing system can be flexible and fast to draw county (city), township (town), field and its “area of interest” small class graphics, with great randomness and variable magnification . It can not only accurately and intuitively map the distribution of Pinus tabulaeformis, the changes of insects, the levels of pests and the design of prevention and cure areas on the map, and the drawn graphics can guide the investigation of insect conditions and pest control so as to be used as pilotage of aircraft pest control Figure It can not only be used independently, but also jointly developed with “Dendrolimus Squatter Statistics Management System”, “Dendrolimus anti-cocision Computer Aided Design System” and “Occurrence and Dependency Prediction System of Dendrolimus” To a certain extent, expand
