摘要: 耕地质量是耕地土壤质量、耕地环境质量、耕地管理质量和耕地经济质量的总和。中国耕地质量总体偏低,中等和低等地共占耕地总面积的2/3以上。中国耕地质量变化态势如何,目前没有统一的认识,较为普遍的看法是中国耕地质量总体水平趋于下降,但农田土壤监测结果表明中国耕地土壤肥力指标总体上呈稳中有升的趋势。论文的分析结果表明,中国耕地质量总体上向好的方向发展,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: Quality of cultivated land can be termed as the summation of such factors as soil quality, environmental quality, management quality and economic quality of the cultivated land. Quality of cultivated land is generally low in China. The area of cultivated land with moderate and low quality accounts for above 2/3 of the total. However, there is no common understanding about how the quality of cultivated land will change among the scientists thought most believe that the quality is generally decreasing. Results from the farmland soil monitoring campaign show that soil fertility of cultivated land is gradually increasing in China as indicators of the fertility present. This confirms the argument that quality of cultivated land as a whole is getting better and better in China though some factors may still be a problem in some parts of China.

Key words: cultivated land, cultivated land quality, China
