- W2387127555 abstract "Using the Minitab software,the paper develops the change characteristics of per capita minimal cultivated land and crop land pressure index based on the dynamics of cultivated land,population and grain in Nanchang Country Jiangxi Province since 1981,and furthermore on the basis of the statistical analysis methods,predicts the cultivated land population grain per capita minimal cultivated land area and crop land pressure index status in the forthcoming 15 years.The results are as follows:total cultivated area and per capita cultivated land area in Nanchang Country have not only been fluctuated apparently since 1981,but also food production and per capita consumption have been increasing by means of the sustaining increase of the productivity of arable land,and per capita minimal cultivated land and crop land pressure index are showing a falling trend.It is found that the total cultivated land in Nanchang County may meet the essential demand for agricultural production and development in the next period of time.However,only depending on increasing investment in agricultural infrastructure and scientific and technological progress so as to continuously improve the productivity of arable land is the fundamental way to reduce pressure on production and to ensure food security." @default.
