摘  要:
以《全国耕地类型区、耕地地力等级划分》为参照标准 ,根据河南省实际 ,将全省划分为豫东、北平原潮土耕地类型区 ,豫南湖积平原砂姜黑土耕地类型区 ,豫西、北山地丘陵褐土、红粘土耕地类型区 ,豫南低山、丘陵黄褐土耕地类型区 ,豫南稻田耕地类型区等五个耕地类型区。在此基础上 ,以土种为单元 ,采用限制因素法和综合归纳法 ,对耕地地力因素进行系统分析和评比 ,评价河南省各土种耕地地力等级。评价结果为 :一等耕地 1 0 .5 5万hm2 ;二等耕地 1 0 3.85万hm2 ;三等耕地 1 37.1 3万hm2 ;四等到十等为中低产田 ,共 5 5 6.60万hm2 ,占全省耕地总面积的 68.88%。

摘  要:
According to the classification of type regions and fertility of cultivated land in China and the fact of Henan province, five cultivated type regions were classified. On the basis of these type regions, taking local soil type as unit and applying the method of limited factor and synthesized induction,the grades of cultivated land fertility of Henan province were appraised through systemic analysis and comparison,on the indexes of cultivated land fertility were gained. The results are the following:the first grade covers 0.11 million ha; the second 1.04 million ha; the third 1.37 million ha; the rest are medium-low yield field and covers 5.56 million ha which is 68.88% of total cultivated land area in Henan province.
