Grain Security of Xinjiang Based on Cropland Pressure Index

【 Objective 】 To study the changing tendency of cultivated land and grain yield in Xinjiang in the past 64 years and forecast the food security situation in Xinjiang in the next 10 years according to the characteristics of cultivated land pressure index, and corresponding countermeasures to ensure grain security in Xinjiang will be put forward.【 Method 】The minimum per capita arable land area and the cultivated land pressure index model and the GM (1,1) gray prediction model were used to quantitatively analyze the food safety level in Xinjiang.【 Result 】The minimum per capita arable land area and cultivated land pressure index of Xinjiang increased from 1949 to 2012, and the cultivated land pressure index in the next 10 years would be greater than 1 and showed a significant growth trend.【 Conclusion 】Xinjiang's food security is unsafe and the future food security situation will become more and more serious. In view of this situation, it is proposed to develop water-saving agriculture, increase agricultural science and technology investment and maintain the amount of cultivated land to ensure food security.
