地球是个有机整体，该整体不仅在不停地运动和变化，而且还在不断地进化，这种进化有其固有的规律。当前，由人类圈和全球环境构成的现代全球系统正处在新的突变期。为此，把现代全球系统演化同地球长期进化联系起来研究，对克服全球问题和实现持续发展是十分重要的。本文主要讨论地球进化的阶梯式上升（stepped rise）、循环形式递增（progressive increase of circulation forms）及进化与条件优化相依（correlation between evolution and condition optimization）三定律，以及该三定律与持续发展的关系。

As an organic whole, the earth is not only uninterrupted motion and change, but continual evolution. This evolution has its inherent laws. At present, the modern global system consisting of anthroposphere and global environment is lying in a new catastrophic stage.For this reason,it is very important for overcoming the global problem and achieving sustainable development to research the evolution of modern global system together with the earth's evolution. Three laws of the earth's evolution are discussed here, that is the law of stepped rise,the law of progressive increase of circulation form and the law of correlation between evolution and conditional optimization, and the relationship between three laws of earth's evolution and sustainable development is also discussed.
