Abstract: Based on analysis and evaluation of the agro-resources and classification of land resource zone and type district,the primary potential productivity and population supporting capacity of land resource in Dabie mountainous region in Hubei Province were estimated by using mathematic models such as GM grey system model,exponential regression model and so on.The results show that the future of PSCL in 2000 is not optimistic.According to low population growth scheme the farmers' living standard in this area can only get to the state of warm and well fed type,and main agricultural products will be short except grain and plant oil.Then some eco-economic countermeasures must be taken to harmonize the relationship among land,population and environment.
