The extensive use of chemical pesticides for pest management in agricultural systems can entail risks to the complex ecosystems consisting of economic, ecological and social subsystems. To analyze the negative and positive effects of external or internal disturbances on complex ecosystems, we proposed an ecological two-sidedness approach which has been applied to the design of pest-controlling strategies for pesticide pollution management. However, catastrophe theory has not been initially applied to this approach. Thus, we used an approach of integrating ecological two-sidedness with a multi-criterion evaluation method of catastrophe theory to analyze the complexity of agro-ecosystems disturbed by the insecticides and screen out the best insect pest-controlling strategy in cabbage production. The results showed that the order of the values of evaluation index (RCC/CP) for three strategies in cabbage production was "applying frequency vibration lamps and environment-friendly insecticides 8 times" (0.80) < "applying trap devices and environment-friendly insecticides 9 times" (0.83) < "applying common insecticides 14 times" (1.08). The treatment "applying frequency vibration lamps and environment-friendly insecticides 8 times" was considered as the best insect pest-controlling strategy in cabbage production in Shanghai, China.
在农业系统中广泛使用化学农药进行害虫防治可能会给由经济、生态和社会子系统组成的复杂生态系统带来风险。为了分析外部或内部干扰对复杂生态系统的正负影响,我们提出了一种生态双面性方法,并已将其应用于农药污染管理的害虫控制策略设计。然而,突变理论尚未最初应用于该方法。因此,我们采用了一种将生态双面性与突变理论的多准则评价方法相结合的方法,来分析受杀虫剂干扰的农业生态系统的复杂性,并筛选出白菜生产中最佳的害虫控制策略。结果表明,白菜生产中三种策略的评价指标值(RCC/CP)顺序为“使用频振灯和环保型杀虫剂8次”(0.80)<“使用诱捕装置和环保型杀虫剂9次”(0.83)<“使用普通杀虫剂14次”(1.08)。“使用频振灯和环保型杀虫剂8次”处理被认为是中国上海白菜生产中最佳的害虫控制策略。
