摘　　要：文章系统地总结了影响生态状况判断的六个理论,分别为:可持续发展、跨越式发展、环境库兹涅茨曲线、熵与混沌理论、耗散结构和社会-经济-自然复合生态系统理论。这些理论是人类认识自然的结晶,而且也是区域生态状况判断坚实的理论基础。在阐述理论的基础上,对中国生态状况作出的准确判断,认为中国的生态状况总体上处于治理与破坏的相持阶段,水土流失、土地荒漠化等得到有效遏制、人们的生态意识不断增强,但传统经济结构和发展模式的调整目标尚未完成,退化生态系统还未得到根本恢复,社会经济可持续发展的目标还需很长时间。这些基于理论分析的判断对于对中国生态建设和可持续发展具有重要指导意义。Some theories to judge ecological situation were summarized in this paper, including sustainable development, leap-frog development, environmental Kuznets＇s curve, entropy and chaos, dissipative structure, and social-economic-natural complex ecosystem, could be helpful to make the adjustment. After presenting the backgrounds, key notes of these theories, applications in adjusting present ecological situation in China were discussed. In the last years, great efforts have been made for eco-environmental conservation which are beneficial to China＇s ecological situation, It is adjusted that present ecological situation in China is in the dead-locked period with the characteristics of between amelioration and degradation. The judges on these theories are much helpful to the ecological construction and the sustainable development of China.
