熵理论视角下的生态安全研究

生态危机产生的深层原因是人类经济活动产生的过量熵增,导致自然界产生了过多的熵,复合生态系统进入高熵状态。以熵理论为指导,首先通过建立复合生态系统的熵变模型,判断系统是处在安全、临界还是危机状态,然后对人类社会生态安全的演变进行了熵分析。最后提出克服熵增、实现负熵的途径,即构建低熵发展模式,遵循自然生态规律,发展生态产业,加强生态教育,建立生态安全风险防范体系等,由此来规避生态风险,化解生态危机,维护我国的生态安全。

Study on the Ecological Security in the View of Entropy Theory

Ecological security is an important component of national security.The deep reason of ecological crisis is that the complex ecological system is in a high-entropy state because of the excessive entropy increase that leads to overabundant entropy in nature by human economic activity.With the theory of entropy as guidance,the paper firstly establishes the model of entropy change on the complex ecological system that can be used to judge the system is in an ecological safe,critical or crisis state.And then the paper makes an entropy analysis on the evolution of human social ecological security.Finnally the paper proposes ways to overcome entropy increases and achieve negative entropy so as to avoid ecological risks,resolve ecological crisis and maintain Chinese ecological safety by building the low-entropy mode,following the laws of natural ecosystem,developing eco-industries,enhancing ecological education and establishing the risk prevention system of ecological security.
