- W2370296666 abstract "This paper,helped by Excel software and based on the analysis of dynamic fluctuation of cropland,population and grain output since Henan Province opened to the outside world,analyzes variant characteristics of minimum cropland acreage per capita and pressure index on cropland.Adopting the predictive theory,it also makes a prediction of its population,grain output and minimum cropland acreage per capita and pressure index on cropland in the coming 15 years with the following research result: since 1978,although cropland acreage per capita has been on the decrease against the boost of cropland productivity,grain output and per capita quota has been on the increase,with the tendency of decrease in minimum cropland acreage per capita and pressure index on cropland.The coming 15 years will see a continuous decrease in minimum cropland acreage per capita and pressure index on cropland.Hence,it is the only fundamental channel to rely on increasing investment and scientific advancement,boost cropland productivity,alleviate cropland pressure and guarantee grain production." @default.
