| 摘要: |
| 为满足当前耕地质量评价和管理需要，合理确定耕地质量的内涵，利用文献综述法和总结归纳法，从时间角度，梳理国内外耕地质量内涵的发展。结果表明：1）国内外耕地质量内涵从单一的适宜性评价阶段发展到生产力、生态、健康等多维度的综合性评价阶段，是不断变化发展的过程；2）目前，由于国家和公众对粮食安全、生态安全、耕地健康以及景观多样性的需求，决定了当前耕地质量内涵必须从耕地生产特性、生态特性、健康特性和景观特性等角度定义。研究认为，未来的耕地质量评价工作，需综合考虑耕地的生产、生态、健康及景观等方面，在耕地质量评价单元、评价尺度、评价方法、评价指标选取等方面进行深化研究，从而为耕地三位一体保护提供一定理论支撑。 |

| Abstract: |
| In order to meet the current arable land quality assessment and management needs,determine the connotation of arable land quality reasonably,a literature review method and summary induction method are used from the perspective of time,to sort out the development of domestic and foreign arable land quality evaluation connotation in this study.The research results show that:1)The connotation of arable quality at home and abroad ranges from single suitability evaluation to productivity,ecology,health,and other dimensions of arable land quality assessment.2)At present,due to nation and public needs for food security,ecological security,arable health,and landscape diversity,determined that the current connotation of arable land quality must be defined from the perspectives of arable land production characteristics,ecological characteristics,health characteristics and landscape characteristics.The study recommends that the future assessment of arable land quality should comprehensively consider the comprehensive characteristics of arable such as production,ecology,health,and landscape,and people should further research on the quality evaluation unit,evaluation scale,evaluation method and evaluation index selection of arable land,thus providing theoretical support for the management of arable land trinity. |
