摘要： The extensive input of chemical insecticides for pest control is considered as a serious risk to the environment, and the ecological disturbance of chemical insecticides has both positive and negative effects on complex agro-ecosystems. This paper proposed an indicator based on ecological two-sidedness theory and Shannon entropy, which is intended for analyzing informational complexity in a decision network of the chemical insecticide pollution management. The results indicated that the order of the value of R-CC/CP index (where the R-CC/CP index matrix WVCC/CP is defined as the index optimization matrix of 'comprehensive cost divided by the index optimization matrix of comprehensive profit) for three insect pest-controlling strategies in scallion fields was "applying frequency vibration lamps and environment-friendly insecticides 8 times" (0.8714) < "applying trap devices and environment-friendly insecticides 9 times" (0.8858) < "applying common insecticides 15 times" (0.9077). The treatment "applying frequency vibration lamps and environment-friendly insecticides 8 times" was recognized as the optimal strategy for chemical insecticide pollution management in scallion fields in Shanghai, China. The results demonstrate that our proposed ecological indicator might arouse the interest of policy Makers and eco-environmentalists who seek to minimize the use of chemicals, and the farmers who hope to optimize pest-controlling strategies in practice.
