摘要:
 基于GIS技术，根据印台区耕地第2次土壤普查资料和“测土配方施肥”采样调查分析结果，利用县域耕地资源管理信息系统，对铜川市印台区耕地地力进行了定量评价分级。结果表明，印台区总耕地面积为19 177.85 hm2，占总土地面积的31.50%；其中一级地、二级地、三级地、四级地和五级地的面积分别为3 692.66、4 991.53、2 644.04、6 568.90 hm2和1 280.72 hm2，质量较低的四、五级地占地比例很高，达40%以上；地力水平整体处于国家标准的中等偏下等级。影响耕地地力水平的主要限制因子是地形起伏较大、地块分布散碎，缺乏灌溉条件和基础设施较差；今后应加强有限耕地资源的保护，大力开展土地整理，兴建水利工程，完善基础设施建设，建成一定数量的高标准基本农田。
Abstract:
 The farmland productivity in Yintai District was assessed and classified based on "county arable land management information system", information collected in the second national soil survey, and the analysis results from the balanced fertilization on soil testing. The results showed that the total cultivated area of Yintai district was 19 177.85 hm2, accounting for 31.50% of the total land area. The areas of the 1st, 2nd, 3rd, 4th and 5th grade cultivated land were 3 692.66, 4 991.53, 2 644.04, 6 568.90 and 1 280.72 hm2, respectively. The 4th and 5th grade cultivated land with poor quality accounted a large proportion (over 40%). Soil fertility quality in the whole district was in lower-middle level according to national standard. The main limiting factors influencing the soil fertility were the undulating terrain, scattered land distribution, lack of irrigation condition, and poor infrastructure. Related countermeasures were proposed, such as to strengthen the protection of limited land resources, vigorously carry out land consolidation and the construction of water conservancy projects, improve infrastructure construction, and build basic farmland with high standard.
