Abstract:

The paper quantifies cultivated land resources economic value, social insurance value and ecological service value in Beijing from 1990 to 2005. The results indicate that: (1) The economic value per hectare increased rapidly from 12.57×104 yuan in 1990 to 108.12× 104 yuan in 2005. (2) In Beijing region, the social insurance value supplied by cultivated land resources is low, but the demand for the social insurance value of the rural residents is high. The supply is 49.19 ×104 yuan/hm2 in 1997 and 74.82 ×104 yuan/hm2 in 2005, while the demand is 160.56 ×104 yuan/hm2 in 1990 and 305.48 ×104 yuan/hm2 in 2005. As the most important basic resources for rural population, cultivated land resources have been overexploited, thus the rural social insurance system should be established as soon as possible, shifting land insurance function out. (3) The total ecological service value went up at first, then decreased greatly, being 142.75 ×108 yuan in 1990, 171.21 ×108 yuan in 1994 and 70.87 ×108 yuan in 2005, respectively, which is due to the decrease of cultivated land resources in Beijing region. But the total ecological service value demand and diversification demand increased because of population growth and living standard raising. In order to keep and improve the vegetation cover, the government should make some ecological compensation for the rural residents. Finally, the paper puts forward that in order to preserve cultivated land resources, the interests of every value subject need to be taken into account, especially the farmers' interest, and that the three values of cultivated land resources would be coordinated.
