The scenic beauty of landscape obtained by testing the public taste, landscape vulnerability and landscape threshold value that is a token of resistance, assimilation and restoration ability to disturbance, and landscape susceptibility expressing the attention extent by public, were then summarized combining the physical circumstance in China, which might be helpful for natural conservation in China.
