摘　　要：耕地作为植物生长的载体,是重要的农业生产资料。随着社会进程的不断推进,耕地质量的重要性日益凸显。提升耕地质量对增强耕地生产力,保障国家粮食安全具有重要意义。本研究在总结前人研究的基础上,对耕地质量的内涵进行了归纳总结,即耕地质量可概括为耕地环境、耕地土壤属性、耕地管理水平等因素共同作用下所呈现出来的耕地综合产出能力。耕地土壤属性是耕地质量最直观的表现,一直是研究的重点;本研究选择土壤类型、土壤质地、土壤肥力和耕层结构等土壤属性作为表征耕地质量的重要指标,概述了其对耕地生产力所产生的影响效应。以期为耕地质量综合性和系统性研究提供指引。As the carrier of plant growth,cultivated land is an important means of agricultural production.With the progress of the society,the role of cultivated land quality becomes increasingly prominent.Improving the quality of cultivated land is of great significance to enhance the cultivated land productivity and ensure the national food security.Based on previous studies,this paper summarized the definition of cultivated land quality,which could be understood as the comprehensive productivity of cultivated land under the combined action of cultivated land environment,cultivated land soil property,cultivated land management level and other factors.Soil property of cultivated land is the most intuitive expression of cultivated land quality and has been the focus of the research.In this paper,soil properties such as soil type,soil texture,soil fertility and plough layer structure were selected as major indexes,and their effects on cultivated land productivity were summarized.At present,the research on cultivated land quality is in the preliminary stage,and a comprehensive and systematic research should be the direction in the future.
