我国耕地质量总体偏低已成为人们的共识,然而,我国耕地质量变化态势如何,目前没有统一的 认识。目前较为普遍的看法是我国耕地质量总体水平趋于下降,但农田土壤监测结果表明我国耕地土壤肥 力指标总体上呈稳中有升的趋势。分析结果表明:我国耕地质量总体上向好方向发展,但耕地部分质量要 素和局部区域耕地质量恶化问题突出。 |

Abstract: |
It was commonly recognized that cultivated land quality was overall at a low level in China. However, the change trend of cultivated land quality has not gained the common acceptance at present. The general view was that cultivated land quality tended to drop as a whole, but the results from the farmland soils monitoring indicated that the trend of cultivated soil fertility indices was generally improving steadily in China. The results in this paper showed that cultivated land quality turned into promising direction except some of quality indicators and regions. |
