Abstract: Based on the theories of suitability and rangeland type,the models for suitability degree of grassland organism have been built up,using index of rangeland moist degree for a measure of integrative ecological factor.The index of estimating habitat suitability for grassland organism was given.Some new concepts,incuding grassland habitat index,habitat suitability degree,process of habitat suitability degree were put forward.
