The key to the study of the resources abundance lies in finding out the comparable calculation units and calculation methods for estimating various resources.This paper discusses the method of estimating the amounts of resources in farming, animal husbandry, forestry and fishery on the basis of the net production value, and estimates the average abundance of agricultural resources on the basis of the average value of 1993～1995 in different regions of ChinaIn this paper,the author assumes that the average abundance of China is one, and estimates the average abundance ratios of different regions. On the basis of the above estimation, the efficient areas of agricultural resources in different regions of China are estimated.
