生态系统发展到一定阶段,它的生产者、消费者和分解者之间、或者说,它的能量流动和物质循环能够较长时间地保持着一种动态的平衡,此谓生态平衡。 生态系统之所以能够保持动态平衡,关键在于生态系统具有自动调节的能力,这种能力在一定范围内能够保持生态系统自身的稳定
As the ecosystem develops to a certain stage, its energy flows and material cycles between its producers, consumers, and disintegrators can maintain a dynamic balance for a long time. This is called ecological balance. The key to maintaining the dynamic balance of ecosystems lies in the ability of ecosystems to automatically adjust and maintain their own ecosystem stability within a certain range.
