艺术家常天鹄在风景这个题材上的艺术探索与吴冠中完全相反，他的“碳排景观”直面社会问题。常天鹄更注重心理刻画，更注重人文思想在风景中的确立。

　　In artistic explorations on the subject of landscape painting, Chang Tianhu is completely in opposition to Wu Guanzhong. His "carbon emission scenery" focused on social problem. Chang Tianhu pays more attention to psychological characterization and the establishment of humanistic ideas in landscape.
