摘　　要：选择“农业生态系统框图模型”最佳方案的统计方法,是从多种方案中,采用统计决策进行优选。文中记述了方案选择的衡量标准、量化模型(进行农业植物生态效益和农业动物的物质转化率的计算)和提出不同方案(计算农业经济效益、提出框图模型方案),通过对比分析,确定最优方案。The statistical method of selecting optimum programme on the block diagram model of agricultural ecosystem is the method of us-ing the statistical decision to seek the optimum from many pro-grammes. This paper discusses the measurement criterion and the quantitative model of programme selection and advances pro-grammes of the block diagram model of agricultural ecosystem. Through contrast and analysis of each programme, determines the optimum programme.

关 键 词：农业生态系统 框图模型 最优方案
