| 摘要: |
| 基于耕地系统内部的要素-过程-功能分析，建立“需求-功能-维度”的耕地健康评价理论框架，构建评价指标体系，运用综合指数法、“1+X”累加模型、最小因子法测算耕地健康状况，并以大兴区为例进行验证。结果表明:1)明晰了耕地健康的内涵并从生产能力、耕地弹性、生产环境和产品品质4 个维度构建了耕地健康评价指标体系；2)大兴区耕地图斑的生产能力、耕地弹性和生产环境指数分别为1 135.81~2 807.23、63.95~94.67、0.40~1.00，产品品质指数为100；3)区域内耕地健康等级包括健康、亚健康和病态3种，无不健康耕地，各级别耕地面积分别为4 726.51、19 333.12、16 754.94 hm2，耕地健康评价结果地域分异明显。本研究建立的耕地健康评价指标体系能够较好的反应区域实际情况，可为耕地资源可持续利用提供依据。 |

| Abstract: |
| Based on the factor-process-function analysis within the cultivated land system, the framework of the cultivated land health of demand-function-dimension was established and a cultivated land health evaluation index system was built. The comprehensive index method, “1+X” accumulation model and the minimum factor method were applied to evaluate the health status of cultivated land by taking Daxing District as an example for verification. The results indicated that: Firstly, the connotation of cultivated land health was put forward and the cultivated land health evaluation index system was constructed from four dimensions, e. g. potential productivity, cultivated land resilience, production environment and product quality. Secondly, the potential productivity, cultivated land resilience and production environment index of cultivated land in Daxing District ranged from 1 135. 81 to 2 807. 23, 63. 95 to 94. 67 and 0. 40 to 1. 0, respectively. The product quality index of the four dimensions were 100. Lastly, the cultivated land health grades included healthy, sub-healthy and morbidity in the region and no unhealthy cultivated land. Moreover, the cultivated land areas at above three levels were 4 726. 51, 19 333. 12 and 16 754. 94 hm2, respectively. The cultivated land health evaluation results were proved the different across regions. In conclusion, the cultivated land health evaluation index system established in this study can better reflect the actual situation of the region and provide references for the sustainable utilization of cultivated land resources. |
