摘　　要：利用模糊物元分析方法对黑龙江八五○农场2204块耕地地力进行了评价和分级,为该地区耕地资源的合理利用和科学管理提供数据支持.选取影响耕地生产力的养分含量、理化指标等作为耕地地力评价的影响因子;依据各评价因子对农作物生长过程的影响特点选择其相应的隶属函数和函数转折点;通过对关联系数的标准化来确定各影响因子的权重;应用模糊物元分析方法求出该地区的全部地块的关联度,在对关联度的直方图分析的基础上将八五○农场耕地分为6个等级,从1级到6级,各级耕地面积占总面积的百分比分别为1.04%、11.71%、47.73%、34.85%、4.76%和0%.地力评价分级结果表明：八五○农场耕地质量在中等偏上,评价结果与耕地实际生产能力基本相符,说明本文提出的方法的有效性和准确性.Fuzzy matter-element analysis was adopted to evaluate and grade the arable soil in Heilongjiang Farm 850, which provides the data support for rational utilization and scientific management of land resource. The soil nutrient content, physicochemical indexes, which influence the land yield, were employed as the influencing factors of land quality evaluation. According to the influence of each factor on the process of the growth of farm crops, the corresponding membership function and its key points were selected for every influencing factor. The weight of each factor was determined by the standardizing of connection coefficient. The fuzzy matter-element analysis was applied to calculated the correlation degrees of 2204 pieces of arable soil, which were classified into 6 levels, from level 1 to level 6, the percentages of farmland in each level account for 1.04%、11.71%、47.73%、34.85%、4.76% and 0 % respectively. The grading results show that quality in farm 850 is above medium level. The evaluated result is consistent with the actual farmland yield, which shows some accuracy and validity of the proposed method in the paper.
