| 摘 要： | 耕地利用与保护需要对耕地质量进行多维管理,多维耕地质量评价是耕地资源管理的重要依据,而县级尺度耕地质量评价是中国耕地质量管理的基础。根据耕地质量内涵,构建反映不同质量维度耕地质量的方法,是客观评价耕地多重质量的必然要求。本文以“需求-质量维度-指标-限制系数-耕地质量”理论框架为基础,构建了基于土壤、生态、环境和管理四个质量维度的县域耕地质量指标体系。利用多源多尺度数据,采用限制系数逐级修正的方法,以北京市大兴区为例进行了耕地质量评价方法的研究,并将评价结果与相关方法进行了对比分析。研究结果表明：①大兴区耕地质量处于中等偏上水平,环境质量是制约耕地质量提升的主要因素;②本研究考虑了耕地的环境质量,因此评价结果与基础地力评价和农用地质量分等成果有一定差异;③构建的耕地质量评价指标体系融合了现有的农用地质量分等指标、耕地地力指标、土壤环境指标等,具有较强的包容性和开放性;④根据非加和及限制因子原理,采用限制系数逐级修正的方法,客观反映了县域耕地质量差异。该评价方法不仅可以评价耕地质量,还可定量评价分维度质量,是对已有成果评价方法的有效补充,可以为中国耕地资源“数量、质量、生态”三位一体的管理需求提供有效支撑。 |

| Abstract: | Cultivated land use and protection require multidimensional management of cultivated land quality. As the quality evaluation of cultivated land at the county level is the basis of quality management of cultivated land in China, we built a comprehensive quality indicator system at the county level under the multidimension of cultivated land quality including soil, ecology, environmental and management quality based on the theoretical framework of ‘demand - quality dimension - indicator - limiting coefficient - comprehensive quality of cultivated land’. This research was carried out in Daxing District of Beijing using multi-source and multi-scale data and step by step modification by limit coefficient. We found that the quality of cultivated land in Daxing District was in the middle level, while environmental quality was the main dimension restricting the promotion of cultivated land quality. The result is different from the achievement of cultivated land productivity evaluation and agricultural land utilization classification since the environmental quality of cultivated land was considered n in our evaluation. The cultivated land quality evaluation index system integrated indicators of agricultural land quality, cultivated land productivity and soil environment which has strong inclusiveness and openness. The differences in county cultivated land quality were objectively reflected in the evaluation result via step by step modification through limit coefficients according to non-additive and limiting factors. Cultivated land quality evaluation in this study is an effective supplement to the existing evaluation achievement and could support China's trinity management strategy of cultivated land as it not only properly evaluates the comprehensive quality of cultivated land but also quantitatively evaluates sub-dimension quality. |
