摘要: 笔者运用耕地压力指数模型和灰色系统理论GM(1,1)模型,对吉林省2003—2012 年间的耕地利用压力指数时空分异特征进行分析,并对其动态变化和未来发展趋势进行了预测。研究结果显示:随着时间的推移,加之国家放开“二胎政策”人口不断在增加,未来人口会出现增加趋势,即使在规定未来十年内人们的人均食物需求量也会不增加的基础上,最小人均耕地面积的增加幅度越来越小,以及大量耕地向建设用地转换,使得耕地压力指数有过大的趋向,而且2017—2027 年吉林省的耕地压力指数处于上升的趋向,即使耕地压力不是很明显,但仍不可忽视。过大的趋向,而且2017-2027年吉林省的耕地压力指数处于上升的趋向,即使耕地压力不是很明显,但仍不可忽视。

Abstract: This paper uses cultivated land pressure index model and the gray system theories GM (1, 1) model, the cultivated land using of Jilin province during 2003-2012 time and space differentiation characteristics were analyzed, and the pressure index and its dynamic change and trend prediction about the future.The results showed that: Jilin province cultivated land with the passage of time, and let go of the "two-child policy" in the population increasing, the future trend of the population will be increased, even if people in the future ten years per capita food demand will not increase, on the basis of the minimum area of cultivated land per capita increase rate tends to small, and a large number of cultivated land to construction land conversion, cultivated land pressure index has a tendency to be too large, and cultivated land pressure index of Jilin province in 2017-2027 in a rising trend, even if the cultivated land pressure is not very obvious, but still can not be ignored.
