| 中文摘要: |
| 为科学评价耕地资源，实现耕地的有效管理，提高土地利用效率，通过文献法对耕地质量和产能的评价指标进行梳理，利用地理探测器进行指标筛选，采用特尔斐法确定指标权重，应用加权求和法对指标系数进行修正，利用连乘积法计算耕地质量与产能指数，系统科学地构建耕地质量和产能评价体系。结果表明，宾阳县耕地质量整体情况良好，等别为优等和良等的耕地面积占99.95%，东北部耕地等别略低于西南部，其等别差异主要原因为土地利用方式不同和土壤健康状况的差异。耕地产能等别中旱地等别主要集中在11等，水田等别主要集中在7等，呈现中部高四周低的分布规律，中心城镇地势平坦、管理水平高是造成耕地产能等别差异的主要原因。研究表明，应用本研究构建的指标体系得到的宾阳县耕地质量评价结果能够很好地反映耕地实际质量状况，说明评价指标体系合理，适用性较强。 |

| In order to scientifically evaluate and classify cultivated land resources, realize effective management of cultivated land, and improve land use efficiency, the evaluation indexes of cultivated land quality and productivity were sorted out through literature method. In this study, the indicators were screened by geographical monitor, index confirmation and weighted summation were modified by Delphi method. The cultivated land quality and productivity index were calculated by using the method of continuous product, and the cultivated land quality and productivity evaluation system was constructed systematically and scientifically. The results showed 99.95% of the cultivated land in Binyang County was excellent or good, which was slightly lower in the Northeast than in the southwest; Among the cultivated land productivity grades, the dry land grade was mainly concentrated in the 11th grade, and the paddy field grade was mainly concentrated in the 7th grade, showing a distribution pattern of middle high and low around. The flat terrain and high management level of central cities and towns are the main reasons for the differences in cultivated land productivity grades. The results of cultivated land quality evaluation in Binyang County show obvious regularity, which can well reflect the actual quality of cultivated land, indicating that the evaluation index system is reasonable and applicable. |
