In this paper, the optimal analytic hierarchy process was used to establish a comprehensive evaluation model for the physicochemical properties of composite sustained-release membrane materials based on water absorption (), water permeability (), tensile strength (), elongation at break (), fertilizer permeability (), and viscosity (), and the optimal ratio parameters of membrane material were determined. Analytic hierarchy process (AHP) combined with correlation analysis was used to construct the judgment matrix of physicochemical properties, which passed the consistency test, and to determine the weight and ranking of each index: (0.6144) > (0.1773) > (0.1561) > (0.1311) > (0.0775) > (0.0520). The comprehensive scores of sustained-release membrane materials under different treatments were calculated based on normalized data samples and weights. It was determined that the percentage of each component in the best comprehensive performance of the slow-release membrane material was as follows: polyvinyl alcohol, polyvinylpyrrolidone, zeolite, and epoxy resin were 7.3%, 0.7%, 0.5%, and 2%, respectively.
本文采用最优层次分析法，基于吸水率、透水性、拉伸强度、断裂伸长率、肥料渗透率和粘度，建立了复合缓释膜材料理化性能综合评价模型，并确定了膜材料的最佳配比参数。运用层次分析法（AHP）结合相关性分析构建理化性能判断矩阵，该矩阵通过了一致性检验，并确定了各指标的权重及排序：（0.6144）＞（0.1773）＞（0.1561）＞（0.1311）＞（0.0775）＞（0.0520）。基于归一化数据样本和权重计算了不同处理下缓释膜材料的综合得分。确定了缓释膜材料综合性能最佳时各组分的百分比分别为：聚乙烯醇7.3%、聚乙烯吡咯烷酮0.7%、沸石0.5%、环氧树脂2%。
