地球生命系统与可持续发展

为论证可持续发展是人类必须进行而且是可以实现的发展模式，应用热力学原理分析了地球生命系统广义热力学循环，计算了地球生命系统的能流与熵流，在此基础上，结合中国国情，对不同发展模式CO2排放进行比较。结果表明，开发利用对环境友好的可依赖新能源，提高资源的有效利用率，同时资源利用以最少破坏环境为准则，是可持续发展的关键。

Earth Life System and Sustainable Development

This paper demonstrates that mankind can and must be on sustainable development. Based on the law of thermodynamics,generalized thermodynamics cycle of the earth life system was analyzed and the energy flux and entropy flux of the earth life system were calculated. The result indicated that sustainable development is necessary and achievable for mankind. On the basis of above, the carbon dioxide (CO_2) emission in three development models was further analyzed in connection to the situation of China. It proved that new reliable and friendly energy resource to the environment should be developed in China and the primary energy ratio should be improved in order to achieve sustainable development.
