摘要: 要实现基本农田科学划定与管理,土地质量评价科技成果是其重要的技术支撑之一。在掌握鄯善县农用地分等成果中耕地的盐渍化程度、灌溉保证率、自然等别等信息基础上,借助GIS技术,筛选出优质耕地,与现状基本农田图斑进行叠加分析。结果显示,现状基本农田中存在着“保劣不保优”的现象,尚有部分质量较好的耕地可划入基本农田。实例研究表明,将农用地分等成果应用于基本农田划定工作可以简单、有效地为划定提供参考和依据,使基本农田划定更为科学合理。

Abstract: In order to realize the scientific definition and management of prime farmland, using outcome of land assessment is one of important technology support. On the basis of master the farmland information about the degree of salinity, probability of irrigation, natural quality grade and so on in the outcome of land quality assessment, to filter out high-quality farmland and conduct an overlay analysis with the existing prime farmland polygon with the help of GIS technology. The results showed that: a phenomenon that there were some low-quality land in the prime farmland and some high grade land could become prime farmland. This case study showed that using outcome of land quality assessment to confirm quantity of prime farmland could provide references and bases simply and effectively, and make it more scientific and rational.
