摘  要：
将安阳市土壤图、土地利用现状图叠加确定评价单元,选取土壤条件、土壤养分、立地条件、农田设施水平4个方面共计11个评价指标,计算耕地地力综合指数,然后对耕地地力进行综合评价,以便为今后耕地资源综合利用、质量管理提供决策依据。结果表明,安阳市一至五等地分别占耕地总面积的的27%、44%、22%、4%、3%,一等地主要分布在滑县中部、内黄县北部、安阳县中东部、汤阴县中部以及市辖区东部的平原地区;二等地主要分布在滑县、内黄县、汤阴县、安阳县、市辖区的中东部平原以及林州市中部山间盆地地区;三等地主要分布在滑县南部、内黄县南部、林州市中东部、安阳县西部、市辖区西部、汤阴县的中西部;四、五等地主要分布在林州市的中低山地区及安阳县、汤阴县、市辖区西部的垄岗和丘陵地区。安阳市耕地地力一至五等级依次对应国家耕地地力等级体系中的一、二、三、五、七等级。

摘  要：
The Anyang soil map,present landuse map were overlaid to confirm the evaluation unit. Eleven evaluation indexes were selected from soil condition,soil nutrient,sitecondition,agricultural facilities to calculate farmland productivity comprehensive index,then evaluating the farmland productivity to provide decision-making information for comprehensive utilization and quality management of farmland resources.The results showed that Anyang farmland class ranked from one to five taking up 27%,44%,22%,4%and 3% of the total area. The first class farmland distributed throughout the middle of Huaxian,the north of Neihuang county,the middle east of Anyang county,the middle of Tangyin county,and the east plains of municipal districts. The distribution of the second class was mainly in Huaxian,Neihuang county,Tangyin county,Anyang county,the middle east plain of municipal districts and middle of Linzhou mountain basin area. The third class mainly spreaded across the south of Huaxian,Neihuang county,the middle east of Linzhou city,the west of Anyang country and municipal districts,and the middle west of Tangyin county. The fourth and fifth class farmlands distributed over low-medium highland of Linzhou,Anyang county,Tangyin county,the west mound and hilly area of municipal districts. The one to five class farmland of Anyang city were equivalent to the one,two,three,five,seven class of the state farmland productivity system.
