【摘要】 根据生态工程加环原理 ,在互花米草生态工程 (SpartinaalternifloraEcologicalEngineering ,SAEE)基础上设计一个深度开发的增益环 ,选取天然植物纤维与互花米草提取物———生物矿质液 (Biolog icalMineralLiquid ,BML)共同制成降脂胶囊 ,并应用能值分析的方法对SAEE +胶囊的加环设计 (SAEEandCapsuleSAEEC)进行了经济、生态、社会复合效益评估 .与SAEE相比 ,加环设计 (SAEEC)的经济投入增加 ,能值投资比率 (Emergyinvestmentratio ,EIR)是SAEE的 1.37倍 ;经济收益是SAEE的 2 .13倍 ,经济收益产投比是SAEE的 1.4 6倍 ;净能值效益 (Netemergyyield ,NEY)是SAEE的 3.18倍 ,净能值产出率(Emergyyieldratio ,EYR)是SAEE的 2 .2 0倍 ,经济效益和生态效益均得到提高 ,体现了生态工程加环增益的基本设计原则更多还原

【Abstract】 Based on the principle of multi-grade utilization of resources to get ecological,economic and social benefits of ecological engineering,this paper designed an added loop,following the Spartina alterniflora Ecological Engineering (SAEE).All the added loop design included SAEE,and the capsule was named SAEEC.In the added loop design,the Biological Mineral Liquid (BML) was made into antihyperlipidemia capsules,of which,the total flavonoids added up to 9.58mg·g -1.Emergy analysis method was applied to evaluate the SAEEC project.Compared with SAEE,the added loop design increased emergy investment ratio (EIR) by 1.37 folds,net economic benefit of the SAEEC by 2.13 folds,economic yield /input ratio by 1.46 folds,net emergy yield (NEY) by 3.18 folds,and net emergy yield ratio (EYR) by 2.20 folds,showing its more efficiency.更多还原
