摘要
以北京市留民营农业生态工程为例,从系统中能量流动分析出发,阐述了能量摄取效率、同化效率、生长效率和利用效率的概念和计算方法,指出通过生态效率计算,指导系统调控,对于提高生产效益的重要作用。
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.
