Some considerations about the dynamic balance of the total cultivated land quantity in China.

Keeping the dynamic balance of the total cultivated land quantity in China is not only necessary for national grain security and the fundamental transformation of land use patterns, but also beneficial to macrocontrol of national economic development. The realistic possibility of maintaining the dynamic balance is discussed from five aspects:increasing utilization efficiency of the existing urban land; compacting rural community distribution. consolidating existing cultivated land; reclamating waste land. and exploiting virgin land suitable for agriculture use. Four strategies about realizing the dynamic balance are proposed:strictly controling the total land supply for building; speeding up to establish market system for cultivated land protection; prohibiting changing cultivated land into garden plot or fish pond arbitrarily, strenghtening the examining and approving management of agriculture construction appropriating cultivated land.
