摘　　要：基本农田划定应以科学的土地质量分级为基础,而农用地分等工作是从耕地生产能力出发划定出区域的耕地质量的差异。所以,该文以北京市房山区为研究对象,依据农用地利用等别成果,借助聚类分析和地理信息系统手段,提出了基于农用地利用等别划定基本农田保护区的方法和手段。研究结果表明:房山区现有的基本农田布局中的耕地质量差异大,涵盖了从7等到21等的各等别的耕地,部分等别高的耕地划到一般农田;依据农用地利用等别划定的基本农田保护区中,平原区耕地利用等别集中在18到21等,山区集中在10到18等,基本农田总面积数增加3520.52hm2,按照各等别对应的标准粮计算基本农田的生产能力提高44749t,而且平原区和山区的耕地生产能力差异很大。可见,利用农用地利用等别的成果进行基本农田划定,以优先划定高等别的耕地资源为基础将基本农田划定与耕地生产能力保护紧密结合,为区县尺度的基本农田划定提供了科学依据。Scientific classification of land quality is the foundation of planning the prime farmland protection zone, and classification of farmland is one kind of farmland quality valuation method, reflecting the difference of land quality through setting farmland natural quality grade, utilization grade and economy grade. So the results can be used in the planning of prime farmland protection zone. In this paper, we take the Fangshan district in Beijing as a example, choose the farmland utilization grade as the main index, and have attempted to planning the prime farmland protection zone applying cluster analysis and GIS technology. The results show that land quality of the prime farmland is large difference in Fangshan district at present, covered from grade 7 to grade 21, and some high-grade cultivated land has been planned as general farmland. The prime farmland planned based on utilized grade covered from grade 18 to grade 21 in the plain area, from grade 10 to grade 18 in the mountain area. Comparing with the situation now, the total area of the prime farmland would increase 3520.52 hm^2, the prime farmland productivity could increase 44749 t according the relationship between utilized grade and standard food output. The study shows that the farmland utilization grade can be used in planning the prime farmland protection zone.
