摘要
为了对沼气生态农业模式结构、功能和效益进行综合定量评价,该研究结合沼气生态农业模式自身的结构和功能特点,以生态农业模式评价指标体系为基础,选择了17个指标构建了沼气生态农业模式综合评价指标体系,应用层次均权法确定了沼气生态农业模式综合评价各指标的权重,在此基础上,运用综合指数法构建了沼气生态农业模式综合评价模型。并以宝鸡市2个典型沼气生态农业模式(陇县"沼气池—厕所—畜舍—菜(果、粮)"庭院生态农业模式和千阳县"桑—蚕—双孢蘑菇—畜舍—沼气池"生态农业模式)的研究数据对模型进行了验证,评价结果与实际情况吻合,表明该研究所提出的评价指标体系和模型具有适用性。
In order to quantitatively assess the structure,function and benefit of biogas eco-agricultural models,based on the studies of eco-agricultural model evaluation index system,17 indicators were selected to construct a comprehensive evaluation index system of biogas eco-agricultural model,multilevel averaging weight method was used to confirm the weights of indices,the assessment model was constructed by comprehensive evaluation method.We also verified the model with the data of two typical biogas eco-agricultural model（sLongxian＂biogas digester–toilet-stable-vegetables, fruits,food）＂courtyard ecological agriculture model and Qianyang County＂mulberry tree-silkworm–agaricus bisporus-stable-biogas digester＂eco-agricultural model）in Baoji City,Shanxi Province,and the assessment results were consistent with the actual situation.It is showed that the evaluation index system and the model have adaptability.
