Abstract


Base on the analysis of nature and social economy status of SanJiaocheng sheep breeding farm eco-system in Qinghai Province, the emergy theory and method were applied to calculate and analyze the NEYR, RIR, ELR and ESI of the SanJiaocheng sheep breeding farm during the year 2002-2006:(1)The total emergy quantity input on the San Jiaocheng sheep breeding farm was 5.00×1029sej, including renewable environment resources、non-renewable environment resources、non-renewable industry attached energy and renewable organic energy which occupied the total input emergy of 7.39%、7.68%、35.15% and 49.77% respectively. The input environment resources occupied 15.08% of the total emergy. In the input attached energy, the renewable organic energy occupied 58.61% of the total input attached energy. In the input environment resources, the non-renewable environment resources occupied 50.96% of the total input environment resources. The EIR of San Jiaocheng sheep breeding farm in Qinghai Province increased from 0.0489 in 2002 to 0.0734 in 2006 gradually, and the overall EIR fluctuates between 0.05 and 0.07.(2) The EYR of SanJiaocheng sheep breeding farm in Qinghai Province increased from 57.4 in 2002 to 83.7 in 2005, and the overall tendency of EYR was on the rise, which indicated that the energy efficiency of economic activity on Sanjiaocheng sheep breeding farm in Qinghai Province increased year by year, and the competitive ability obviously enhanced.(3) The EIR of SanJiaocheng sheep breeding farm in Qinghai Province increased from 0.0489 in 2002 to 0.734 in 2006 gradually, and the overall EIR fluctuates between 0.05 and 0.07, which indicated that the degree of economy opening to the outside world and the utilization of various outside“resources”was low in that area.(4) The ELR of SanJiaocheng sheep breeding farm in Qinghai Province increased from 31.3 in 2002 to 71.4 in 2006, and the general tendency was on the rise, which indicated that the pressure of economic development on the environmental system increased gradually in that area.(5) The EDR of SanJiaocheng sheep breeding farm in Qinghai Province showed a tendency of rising year by year, it increased from 1.50×1014sej/$ in 2002 to 7.98×1014sej/$ in 2006, this mainly because that the gross agricultural production of that area increased slowly during the year 2002-2006 and the decreased exploiting degree of economic system.(6) During the year 2002-2006 the ESI of SanJiaocheng sheep breeding farm in Qinghai Province decreased from 58.46 to 21.8, the general tendency was on the decrease, and the ELR increased from 31.3 to 71.4 at the same period, which showed a rapid rising tendency. From the equation ESI=NEYR/ELR thus it can be seen that the decrease of ESI during the year 2002-2006 was due to the growth rate of ELR was higher than that of NEYR at the same period on the SanJiaocheng sheep breeding farm in Qinghai Province.
