Abstract: Catastrophe progression method was used to evaluate the comprehensive benefits of soil and water conservation in Changting from 1999 to 2011. This paper developed a comprehensive evaluation system with 11 factors selected from 3 aspects: ecological benefits, economic benefits and social benefits. The results indicated that Changting had remarkable achievements in soil and water conservation after 1999, all the benefits were increased with time, the catastrophe membership function values complied with the order as ecological benefits >economic benefits > social benefits, the benefit increase amplitude were decreased with time, and growing steadily since 2008. All these indicating that the system had a coordinated development trend. The conclusion is consistent with the field survey; the results prove that the catastrophe progression method is perfect in performance. It provides a new idea to evaluate the comprehensive benefits of soil and water conservation for other regions.
