通过研究摸清了东北林木鼠害现状、种群数量、动态和变动规律,应用灰色理论系统、多元回归和乏晰综合多因子相关法,建立了鼠害中短期预测模型、综合测报决策模型和微机测报系统。研究了东北林区鼠害区的划分和鼠害类型的划分。总结出以营林生态为主与化学防治相结合的系列配套的综合防治林木鼠害体系。经实施验证,采用此法防鼠害,经济效益、社会效益及生态效益均很显著。
Through the research, we found out the status quo, population quantity, dynamics and variation of rodent pests in Northeast China. By using the gray theory system, multiple regression and multifactor correlation analysis, we established the short-term and short-term prediction model, comprehensive forecasting model and microcomputer Report system. The division of rodent area and the classification of rodent pests in the forest area of Northeast China were studied. Summed up to Yinglin ecological and chemical control combined with a series of integrated support system of forest rodent control. After the implementation of verification, the use of this law against rat damage, economic, social and ecological benefits are significant.
