摘要

实施退耕还林工程以来,安塞县耕地面积、总播种面积和人均耕地面积均有所减少。但是,由于采取了调整种植结构、加大投入、改进技术等有利措施,粮食单产和粮食总产量有增加的趋势。人均粮食没有太大变化,仍保持在350公斤以上(即温饱水平),人均耕地面积仍高于人均耕地面积。由此可见,退耕还林工程并未对安塞县的粮食安全造成负面影响。

Effects of the Grain for Green Project on Grain Production in Ansai County
There has been a decrease in area of arable land,total sown area and area of arable land per capita since the implementation of grain for green project in Ansai County. However, the grain yield per unit area and the total grain output have tended to increase owing to favorable measures taken, such as adjustment of planting structure, increase of investment and improvement of technologies. No great changes have occurred to the food per capita, which remains to be above 350 kg (namely the subsistence level), and the area of arable land per capital is still higher than the area of cultivated land per capita in China. Thus, no negative impacts have been imposed upon food security of Ansai County by the grain for green project.
