While the worldwide standardization of agricultural production has been advocated and recommended, relatively little research has focused on the ecological significance of such a shift. The ecological concerns stemming from the standardization of agricultural production may require new methodology. In this study, we concentrated on how ecological two-sidedness and ecological processes affect the standardization of agricultural production which was divided into three phrases (pre-, mid- and post-production), considering both the positive and negative effects of agricultural processes. We constructed evaluation indicator systems for the pre-, mid- and post-production phases and here we presented a Standardization of Green Production Index (SGPI) based on the Full Permutation Polygon Synthetic Indicator (FPPSI) method which we used to assess the superiority of three methods of standardized production for peaches. The values of SGPI for pre-, mid- and post-production were 0.121 (Level IV, "Excellent" standard), 0.379 (Level III, "Good" standard), and 0.769 × 10(-2) (Level IV, "Excellent" standard), respectively. Here we aimed to explore the integrated application of ecological two-sidedness and ecological process in agricultural production. Our results are of use to decision-makers and ecologists focusing on eco-agriculture and those farmers who hope to implement standardized agricultural production practices.
尽管农业生产的全球标准化已得到倡导和推荐，但相对较少的研究关注这种转变的生态意义。农业生产标准化引发的生态问题可能需要新的方法。在本研究中，我们关注生态双面性和生态过程如何影响分为三个阶段（产前、产中、产后）的农业生产标准化，同时考虑农业过程的正负效应。我们构建了产前、产中、产后阶段的评价指标体系，并在此提出基于全排列多边形综合指标法（FPPSI）的绿色生产标准化指数（SGPI），用于评估三种桃子标准化生产方法的优越性。产前、产中、产后的SGPI值分别为0.121（四级，“优秀”标准）、0.379（三级，“良好”标准）和0.769×10⁻²（四级，“优秀”标准）。在此，我们旨在探索生态双面性和生态过程在农业生产中的综合应用。我们的研究结果对关注生态农业的决策者和生态学家以及希望实施标准化农业生产实践的农民有用。
