在综合介绍现今应用的评价杀虫灯防治农田害虫效益的一般方法的基础上,以防治烟田害虫为例,进一步发展了一种评价其经济、生态和社会效益及其综合效益的可定量化的相对动态的简单算法模型。该算法模型的优点在于,评价指标和权重参数可根据不同的主观或客观要求灵活选用,涉及的相关因素或指标值直观可测,优劣判定标准值明确;经济、生态、社会三大效益都可定量化,可综合评价,也可独立评价,灵活直观,计算简便;客观和主观指标相结合,更符合用户至上的原则;克服了以前各类评价方法的诸多缺陷(如绝对和静态评价,对生态和社会效益没有定量化值,对优劣的判断,没有客观标准值可循等)。其评价结果,对于判断产品是否有广阔的应用前景具有一定的意义。
Based on the general introduction of the general methods used to evaluate the benefit of insect pest control on agricultural pests, the prevention and cure of pests in tobacco fields is taken as an example to further develop a method to evaluate the economic, ecological and social benefits as well as its comprehensive benefits Relatively dynamic simple algorithm model. The advantage of the algorithm model is that the evaluation indexes and weight parameters can be flexibly selected according to different subjective or objective requirements, the relevant factors or index values involved are intuitively measurable, and the standard values for determining superiority and inferiority are clear. The economic, ecological and social benefits It can be quantitative, comprehensive evaluation, independent evaluation, flexible and intuitive, simple calculation; objective and subjective indicators combined with more in line with the principle of the supremacy of users; Overcome the many shortcomings of the previous evaluation methods (such as absolute and static evaluation, There is no quantitative value for ecological and social benefits, judgments on advantages and disadvantages, no objective standard value, etc.). The evaluation result has certain significance for judging whether the product has a broad application prospect.
