| 摘 要： | 耕作便利是表征农田综合质量的重要因素。为准确反映现代农业发展对耕作便利条件的要求，基于农业机械效率视角界定农田耕作便利度，进而构建定量综合评价模型，并在华北平原项目区开展实证分析。结果表明：新界定的耕作便利度强化了农业机械耕作效率的影响，包括田间作业效率和机械通行效率两方面。明确了机械化耕作背景下的连片度、耕作距离和田间道路通达度3个关键指标的内涵与快速获取方法，为准确评价耕作便利度奠定了基础。耕作便利度评价结果显示：研究区82.41%的耕地处于非常便利和比较便利的级别，平均地块面积大，集中连片且交通便利，是发展高效农业、推广机械化耕作的适宜区域；一般便利和不便利级别的田块平均面积较小，分布分散且远离居民点，机械耕作效率较低，不利于发挥规模效益。该研究可为耕地质量评价、高标准农田建设项目选址等提供技术支持。

| Abstract: | Farming convenience degree (FCD) is an important feature of cultivated land. In order to accurately characterize all requirements of modern agriculture for FCD, the definition and its meaning of FCD were introduced. Then, a systematic and comprehensive evaluation model was constructed and applied in a project area of Dingzhou City in Hebei Province. The results showed that the newly defined FCD put farming efficiency on an importance place, which consisted of field work efficiency and traffic efficiency. Three key indexes were thoroughly studied, including connective degree, field road accessibility and farming distance. Their meaning and acquisition method offered the foundation to obtain FCD accurately. The evaluation results showed that the FCD condition of farmland in the study area was good overall. Based on the comprehensive evaluation score, the farm units were divided into four levels. Among that, totally 82.41% of all farmland area was at the level of very convenient or more convenient. These kinds of units mainly had the feature of convergent distribution and large average land area, and also distributed in the area close to roads. It was the appropriate area for developing high-efficiency agriculture and spreading mechanized farming. On the contrary, it was difficult to exert scale benefit and mechanical tillage for farmland of the grades like general convenient and not convenient, because of their small units and scattered distribution. The research can provide technical support and method reference for the project selection and performance evaluation for well-facilitated farmland as well as the evaluation of cultivated land quality. |
