人口容量与适度人口的热力学解释

对于地球的人口容量问题,人口学者曾做过许多尝试,并提出了不同版本的人口容量阙值。本文在借鉴前人的研究成果基础上,把生物圈的能量流动分为外部能量流动和内部能量流动,并在回顾人类社会发展历程中,提出人类社会的发展源自内能流能量的增加和人类对内能流能量使用效率的提高。进而又得出了人口容量和适度人口的热力学模型,及其热力学含义。

A thermodynamic explanation of the population carrying capacity and optimum population

It is concerned that the problem of population carrying capacity and demographist had proposed the different maximum of the population carrying capacity.But,it is hoped that the energy fluxion of the biosphere should be divided into internal and external energy fluxion based on the previously research.Through the retrospect of the history development of human beings,it also suggests that the society development should be derived from the increment of the internal energy fluxion and the improvement of efficiency by using internal energy fluxion.Then,the paper concludes the thermodynamic model and the thermodynamic meanings about the population carrying capacity and optimum population.
