| Abstract: | The importance of analysis and calculation of ecological efficiency in agro ecological
engineering was described systematically. The function of ecological efficiency analysis and
calculation on the increasing of productivity was discussed. Beijing Liuminying agro ecological
engineering was taken as a case study for the introduction of the analysis and the calculation
methods. |
