| 中文摘要: |
| 将能值分析方法引入特色农业生态系统的可持续发展研究中，对漳州市特色农业生态系统进行动态定量分析与评价。结果表明：该系统2011 年的净能值产出率、能值投资率和可持续发展指数分别为6.88、1.14、8.29，与2001年相比均有提高，说明系统具有较好的可持续发展潜力；2011 年的环境承载率为2.07，与其他地区相比，系统发展的环境压力较小。据此，在环境容许的情况下适当加大辅助能值特别是有机能值的投入，促进区域特色农业的产业化发展，将使漳州市特色农业生态系统更具可持续发展的优势。 |
| 英文摘要: |
| The method of emergy analysis and its application in sustainable development of the characteristic agricultural ecosystem were introduced, dynamic quantitative analysis and evaluation of the characteristic agricultural ecosystem in Zhangzhou city were made according to the method. The results showed that in 2011, the net emergy output of the system, the rate of emergy investment and its sustainable development index were respectively 6.88, 1.14 and 8.29, which all increased compared with those in 2001, it indicated that the system had good potential for sustainable development. In 2011, the environmental carrying capacity rate was 2.07, which meant there was less environmental pressure for the systematic development, compared with other regions. Therefore, increasing the investment in remedial emergy especially in organic emergy and promoting industrialization of the regional characteristic agriculture will make the characteristic agricultural ecosystem in Zhangzhou city more competitive in the sustainable development. |
