摘要
采用能值分析法对2008年临洮县农业生态经济系统投入产出状况、运行效率和环境负载进行了系统分析。结果表明,2008年临洮县农业生态经济系统投入能值1.24×1021 sej,产出能值1.32×1021 sej,净能值产出率1.18%,环境负载率6.10%,可持续发展指数为0.19<1.00,属于不可持续的农业生态经济系统。
The input and output, operating efficiency and environmental load of agricultural c system in Lintao County were analyzed by using of the energy analysis method in 2008. The results showed that the investment energy was 1.24 × 10^21 sej, output energy was 1.32 × 10^21 sej, the net emergy output ratio was 1.18%, environmental loading rate was 6.10% of agricultural eco-economie system in Lintao County in 2008, based on the sustainable development index of energy analysis was 0.19 〈1.00, which belongs to the not sustainable agro-ecological economic system.
