Study on method of quantitative assessment of fragile environment

The assessment of degree of fragile environment has been improved, but the most of them still remain at the level of qualitative analysis though some have reached the level of quantitative analysis. There are many problems in these existed quantitative assessments yet. Their use may cause the result of little assessment comparison which will limit their usage and extension. In this paper, a set of method on assessment of fragile environment is established. It is a systematic, complete, objective and flexible method of assessment of fragile environment, and can be easily used in practice. At last, its practicality and accuracy are tested by using it to assess fragile degree of environment within 26 provinces in China.
