Title: Analysis of Food Production and Cropland Pressure Changes in Hongsibu of Ningxia Under the Background of Ecological Immigration
Abstract: The concepts and calculation models of minimum area per capita of cultivated land and the pressure index on cultivated land were used to quantitatively analyse the dynamics of the food production and cropland pressure from 2000 to 2010 in Hongsibu.And then the changes of the grain production,cultivated land,population,and cultivated land pressure index for the next 15 years were predicted.The results of the study showed that: the pressure index of cultivated land from 2003 to 2010 was less than 1,there was no pressure of cultivated land,and comprehensive production capacity of the cultivated land was higher.But the prediction of cultivated land pressure index value showed that the trend of the cultivated land production capacity after the year of 2010 declined,cultivated land pressure index was gradually increasing with the passage of time,so,there were regional food security hidden danger.It was very important to strengthen the protection of cultivated land and grain production,it was only through the increase of investment and the progress of science-technology to raise cropland productivity so that the pressure on cropland would be reduced and the grain production was guaranteed.
