eco-balance An eco-balance refers to the consumption of energy and resources and the pollution caused by the production cycle of a given product. The product is followed throughout its entire life cycle, from the extraction of the raw materials, manufacturing and use, right through to recycling and final handling of waste (生态平衡指的是能量和资源的消耗及特定产品在其生产周期中产生的污染。整个产品的生命周期,从获取原料、生产和使用,一直到废弃物的回收和最终处置的过程均被追踪。); ecological balance The condition of equilibrium among the components of a natural community such that their relative numbers remain fairly constant and their ecosystem is stable. Gradual readjustments to the composition of a balanced community take place continually in response to natural ecological succession and to alterations in climatic and other influences (自然群落中组成成分间的平衡状况,从而使得它们之间的相对数量基本上仍保持恒定,且生态系统是稳定的。 一个平衡的群落会逐步地、连续地重新调整其组成成分来响应自然生态的演替、季节更换和其他的影响。) |
