Abstract: The traditional methods which were used to determine norms for ecological compensation for different kinds of lands usually neglect ecosystem as a whole and are not so applicable in practice because the norms they set are often too high for compensation. In order to determine accurately and objectively norms for ecological compensation for different types of lands, catastrophe progression method was used to analyze and assess service function values of ecosystems, by incorporating research results available. On such a basis, transform factor and equilibrium factor of ecosystem service function values of various types of lands and a model for dynamic accounting of norms for ecological compensation were brought forth based on the catastrophe theory. The model was then applied to calculation of norms for ecological compensation in Jilin Province. According to the calculation, the norm for ecological compensation for farmland, woodland, grassland, wetland, water area and virgin land is 15349, 20185, 16821, 20949, 18268 and 8236 yuan per hm², respectively, in 2012, which is believed to tally quite well with the actual situation of social and economic development in Jilin Province. This example proves that the model is easy to use and quite high in reliability and universal applicability.
