Analysis of Cultivated Land and Food Security Based on Cropland Pressure Index in Fujian Province
Based on the cultivated land pressure index, the population, cultivated land and grain change of Fujian Province were analyzed from 1978 to 2015, and the trend of grain and cultivated land in Fujian Province from 2016 to 2030 was forecasted.The results showed that cultivated land area, grain sown area and grain yield of Fujian Province decreased from 1978 to 2015, and the population increased year by year, which resulted in the gap between grain supply and demand in Fujian Province.It was predicted that the population of Fujian Province would continue to increase from 2016 to 2030.However, the total area of cultivated land and total grain output would continue to decrease steadily, resulting in the increase of the minimum per capita arable land area and the cultivated land pressure index in Fujian Province.Therefore, the future load of cultivated land in Fujian is more serious and the food security situation severe.According to these,the countermeasures were put forward to reduce the pressure of cultivated land in Fujian Province,to ensure the safety of regional grain production and to promote the sustainable development of the region.
