| 摘 要： | 在宜耕性的基础上，为合理提高耕地利用效率、加强生态文明建设和资源可持续利用，以原阳县为例，综合考虑耕地利用效率与宜耕性评价结果，对耕地利用效率进行分区，提出各区域耕地利用效率提升路径。结果表明：从耕地利用效率来看，原阳县耕地利用整体水平不高，其综合效率均值为0.837，纯技术效率和规模效率均有较大的提升空间；从宜耕性评价结果来看，原阳县耕地的适宜宜耕区、基本适宜宜耕区、低适宜宜耕区、流域保护区面积分别占耕地总面积的37.84%、41.36%、19.09%、1.71%，整体宜耕性较强。叠加组合耕地利用效率和宜耕性评价结果，将原阳县耕地利用效率分为保持区、提升区、调整区、保护区。从可持续利用和生态保护角度考虑，结合差异化的整治措施，保持区宜耕性和耕地利用效率均较高，应以维持现有耕地利用效率、延伸耕地的生态和经济价值为重点；提升区宜耕性强、耕地利用效率较低，应通过规模化经营最大限度地提高其有效利用效率；调整区宜耕性差，不宜提升耕地利用效率，应发展生态农业或设施水培农业，在提高耕地经济效益的同时，缓解耕地与生态保护压力；保护区内耕地应逐步退出，充分发挥其湿地功能与生态功能。本研究可为耕地资源的可持续利用提供决策参考。

| Abstract: | In order to reasonably improve the efficiency of cultivated land use, strengthen the construction of ecological civilization and the sustainable use of resources on the basis of cultivated landsuitability, taking Yuanyang County as an example, the cultivated land use efficiency was divided into different regions by comprehensively considering the evaluation results of cultivated land use efficiency and suitability, and the measures for improving the cultivated land use efficiency in each region was proposed. The results showed that from the perspective of cultivated land use efficiency, the average value of cultivated land use comprehensive efficiency in Yuanyang County was 0.837, the overall level was not high, and there was a large space for improvement of pure technical efficiency and scale efficiency. According to the evaluation results of cultivated land suitability, the suitable arable area, basic suitable arable area, low suitable arable area and basin protection area accounted for 37.84%, 41.36%, 19.09% and 1.71% of the total cultivated land in Yuanyang County, respectively, and the arable ability was strong. The cultivated land use efficiency in Yuanyang County was divided into conservation area, promotion area, adjustment area and protection area by superposition of the evaluation results of cultivated land use efficiency and arable land suitability.From the perspective of sustainable utilization and ecological protection, combining with differentiated remediation measures, in the conservation area, maintaining high arable land, arable land use efficiency and extending the ecological and economic value of arable land were the key points.The promotion area had strong arable and low cultivated land use efficiency. It can maximize its effective use efficiency through large-scale operation.In the adjustment area, the suitable tillage was poor, and the utilization efficiency of cultivated land should not be improved. Ecological agriculture or facility hydroponic agriculture should be developed to improve the economic benefits of cultivated land and alleviate the pressure of cultivated land and ecological protection. The cultivated land in the protected area would be withdrawn gradually, and its wetland and ecological functions would be brought into full play. The research results can provide reference for the sustainable utilization of cultivated land resources. |
