害虫微生物防治的目标体系与效益评价方法

Objective System and Benefit Evaluation for Microbial Control of Pests

害虫微生物防治系统是复杂的多目标复合生态系统．对系统进行多目标效益评价有助于了解系统现状，遴选最佳防治技术，根据害虫防治的一般要求，结合微生物防治的有关特点，建立了害虫微生物防治的目标体系．对基于估计相对位置的方案排队法和混合优序图法分别进行改进，用改进算法对系统进行效益评价和方案择优，给出了计算软件．同时指出，在生态系统的评价管理中，多目标决策方法是科学合理、行之有效的定量工具．

The microbial control of pests is a complex and multiobjective ecological system which includes a lot of indices and objectives.Comprehensive evaluation to this multiobjective system will help to select optimum management measure.According to the characteristics of microbial control,the objective system for microbial control of pests was developed. The Ranking Method Based on Relative Position Estimate and the Mix Preference Chart were corrected and improved.Using the corrected algorithms,comprehensive evaluation and plans selection were made on the systems.Meanwhile,the computer softwares for the two corrected algorithms were given in this paper.
