1我国耕地质量和土壤肥力状况堪忧耕地地力后劲儿不足,土壤养分失衡,生态功能变差,污染日趋加剧,这是我国耕地质量的整体现状。2014年,农业部发布的《关于全国耕地质量等级情况的公报》显示,全国耕地按质量等级由高到低依次划分为1~10等。2012年底评价为1~3等的耕地面积占耕地总面积的27.3%,4~6等的占44.8%,7~10等占27.9%。综合
1 The Situation of Cultivated Land Quality and Soil Fertility in China Is Fragile Due to lack of stamina in farmland, imbalance of soil nutrients, deterioration of ecological functions and increasing pollution, this is the overall status of cultivated land quality in China. In 2014, the “Communique on the Grading of Cultivated Land Quality in China” issued by the Ministry of Agriculture shows that the cultivated land in the whole country is divided into 1 to 10 grades in descending order of quality.
