To study the farmers' income as affected by the areal change of cultivated land resources in the poverty areas around Beijing and Tianjin Cities, statistical data of seven poverty-stricken counties in Baoding City from 1997 to 2011 were used to verify the relationship between the two. The seven counties were zoned to be three regions using cluster analysis method, the relationship between cultivated land resources and farmers' income was analyzed, and the regional differences were studied using panel data model. Results indicate that in the three regions(mountainous area, Beijing's surrounding area and Beijing's nearby area), there exists a long-term equilibrium relationship between the cultivated land area and the rural per capita net income. In the mountainous area, the rural per capita net income and cultivated land area are positively correlated, while in the Beijing's surrounding area and Beijing's nearby area, negatively correlated. Moreover, the relationship between the two indicators is different within every region, and there are also differences in the growth rate of rural per capita net income in different areas. The positive or negative relationship between the amount of cultivated land and farmers' income are closely related to farmers' income source and income structure, and also related to regional resource endowments, geographic conditions and socio-economic conditions.
