| Abstract: | 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. |
