| 摘 要： | 通过对塔里木河流域生态输水工程的效应分析,揭示了生态系统反馈机制的原理和特点,强调了负反馈机制的作用,即生态系统在受到外界影响或干扰后,通过一系列的自我调节功能来减轻这种干扰或影响的程度,并力图恢复到平衡或稳定状态.最后,探讨了生态系统反馈机制的作用和意义.

| Abstract: | Effects of water transfer engineering on the ecology of the Tarim River were analyzed,exposing principles and characteristics of the feedback mechanism of the ecosystem,particularly negative feedback of the ecosystem,i.e.while an ecosystem is subjected to external impact or disturbance,it will initiate a series of autoregulation functions to alleviate intensity of the impact or disturbance in an attempt to restore its balance or stability.Moreover,effects and significance of the feedback mechanism of an ecosystem has been explored. |

| Keywords: | human activity ecosystem feedback mechanism Tarim River ecological water demand entropy coupling |
