- Abstract:
- First, the pressure index on arable land was calculated based on the data of arable land, grain and population of Tangshan city from 1984 to 2008. Then, the causes of dynamic change of pressure index on arable land were analyzed. The results are as follows: (1) Total arable land and its per capita volume has continued to decrease; (2) Total grain output and per capita output show the trend of first increased and then decreased; (3) Affected by the trends of total grain output and per capita output, minimum arable land acreage per capita and pressure index on arable land show the similar trends. In the end, the control strategy which was maintaining a certain amount of arable land area and cultivate high-yielding crop was discussed in order to ease the arable land pressure.
