1) Cultivated Land Area Decrease
耕地面积减少
1.
The rates of GDP Growth, Population Growth and Cultivated Land Area Decrease were selected as the three main indicators for analyzing in this paper.
本文选择GDP增长率、人口增长率和耕地面积减少率为主要分析指标,详细讨论了1978~1996年广东省经济增长、人口增加和耕地面积减少之间的关系。
2) Reduction rate of the cultivated area
耕地面积减少率
3) farmland decrease
耕地减少
1.
The purpose of the paper is to overall coordination the relationship between economic development and farmland decrease.
引入区位熵评价方法,对县域内不同地区经济发展对耕地减少的影响程度进行差异分析,探讨从空间角度统筹协调各地区经济发展与耕地减少的关系。
4) Cultivated land
耕地面积
1.
With the combination of GIS technology and remotely sensed data,cultivated land changing trend in regional scale can be easily traced and inventoried in time.
结果表明,在过去50多年里,三江平原耕地面积发生了显著变化。
2.
In Beijing, the cultivated land area has decreased from 456,040 ha in 1981 to 287,633 ha in 2001.
80年代年以来 ,北京市土地利用结构发生了巨大的变化 ,突出表现在耕地面积大量减少。
5) farmland area
耕地面积
1.
It reveals that the difference of the two kinds of farmland area estimates was mainly caused by the difference in the caliber of their measurement units and the difference in the coverage of the data applied in both kinds of estimation.
深入分析耕地面积详查数据与统计数据的来源和计量单位口径以及数据覆盖范围,建立了详查口径耕地面积与统计口径耕地面积的关系方程。
6) cultivated land area
耕地面积
1.
The results showed that: the cultivated land area,the total output and the quantity per capita of grain had been increasing,the pressure index of cultivated land had trended to decrease obviously between 1981 and 2006;but in the comin.
研究结果显示:1978-2006年,内蒙古耕地面积、粮食产量和人均占有量都有所增加,耕地压力指数呈现明显降低的趋势;但未来近十年内,耕地压力指数会增大,到2017年,耕地压力指数将达到1,之后耕地压力指数进一步增大,遭遇耕地危机,严重影响粮食生产的发展。
2.
The conclusions are as follows:① The pressure index in cultivated land in Shaanxi province is gradually increased,cultivated land pressure is mounting,because the cultivated land is greatly reduced and the population increases gradually;② The cultivated land area ch.
结果表明:虽然粮食单产和复种指数不断提高,但是由于耕地面积大量持续减少、人口的不断增多,1978~2005年陕西省耕地压力指数较高,耕地压力较大,并且呈上升趋势;2005年区间耕地压力差异不显著,但区间1996~2005年耕地压力变化差异明显,陕北高原区>秦巴山区>关中平原区。

The surveys and prediction of cultivated land area provide an effective way for cultivated land protection.
耕地保护事关一个地区粮食战略安全问题,而耕地面积的测算与预测为耕地保护提供了决策支撑。
