Abstract:

The relation between the increasing land demand and the security of cultivated land resources is inconsonant. And the inconsonance is always the core problem to be solved in the land use planning. It is valuable to logically predict the quantity of cultivated land resources which could be transformed into land for non-agricultural purpose of a region. Taking grain productivity as a point of penetration, this paper built the model for measuring cultivated land that could be transformed into land for non-agricultural usage (MMCLNT) based on production capacity. Taking Lulong County as an example, the applicability of this model is verified. The study results indicated that: 1)The transferring quantity lies between a data interval, the value depends upon the quality of cultivated land that could be transformed for non-agricultural purpose. 2)Taking Lulong County as an example, the quantity of cultivated land that could be non-agriculturally transformed is 851.87-1547.86 hm2 from now on to the year 2020. Taking grain productivity as a point of penetration, the quantitative analysis about the cultivated land that could be non-agriculturally transformed provides a new method to harmonize the relationship between the land use planning and economic and social development.

Key words: land resources management, MMCLNT, cultivated land could be non-agriculturally transformed, Lulong County
