技术功能层级论下的生态工程失效分析

An Analysis of Ecological Engineering Failure from the Perspective of Technological Function-level Theory

生态工程概念的提出是为了打破环境学界一直以来的人类中心主义传统,它倡导最大限度挖掘并利用自然生态系统本身的共生与协同机制,实现资源的绿色获取。然而在实践过程中,生态工程却频频遭遇失效,这是因为从技术功能发挥的层级看,生态技术同时包含着"局部精确性"和"整体不确定性"两个属性特征,这两个属性来源于科学的去情境性与人类真实生存境遇之间的矛盾,面对这种人—自然境遇的矛盾性,人类应该秉持一份开放的心态并发挥适应性和创造性。

Ecological engineering is proposed with an aim to obtaining energy in a green and natural way as much as possible by taking full advantage of the symbiotic mechanism of natural system. Theoretically it helps break through the mainstream anthropocentrism, but practically it encounters a lot of failure. Ecological engineering failure is mainly due to the two attributes embedded in technology-- low-level liability and system-level risk, which arise from the tension between de- contextual scientific research paradigms and human beings＇ real living circumstances. To cope with this tension, it is reasonable for the mankind to keep an open-minded attitude and become more adaptive and creative.
