Evaluation of Efficacy about Economically and Ecologically to Cultural System of Apostichopus Japonicus through Energy Systemic Model

摘要：

Evaluation index-EYR, ELR and ESI were selected to analyze efficacy about economic efficacy and ecological efficacy in cultural system of Apostichopus japonicus by EMERGY theory. Energy value fig of cultural system of Apostichopus japonicus was established take advantage of energy systemic model, and various part of distributions about energy value in cultural system of Apostichopus japonicus was analysed. Results indicated that economic efficacy of each energy value unit in cultural system of Apostichopus japonicus was higher than piscine intensive cultural model significantly; the cultural system of Apostichopus japonicus had a larger environmental capacity and sustainability.
