| 为探讨耕地质量提升潜力，本文以濮阳县为研究区，根据 2019年度耕地质量等补充完善成果，采用自然等效约束指数模型计算各耕地单元的约束程度，确定主要限制因素并分析耕地质量提升潜力。结果表明:中度限制耕地占耕地总面积的 70.3%，轻度限制耕地占耕地总面积的 29.7%。耕地质量理论提升潜力 0~1等，可提升 1个等别的耕地面积为 22237.10 hm2；现实提升潜力 0~1等，可提升 1个等别的耕地面积为 17873.36 hm2。同时提出了下一步耕地质量提升重点，研究成果为本区耕地整治和提升提供参考。 |
| 英文摘要: |
| To explore the potential for improving cultivated land quality, Puyang County was selected as the re.search area. Based on the 2019 results of cultivated land quality supplementation and improvement, the restrictiondegree of each cultivated land unit was calculated using the natural equivalent restriction index model. This ap.proach helped identify the dominant restrictive factors and analyze the potential for improving cultivated land qual.ity. The results showed that the moderately restricted cultivated land accounted for 70.3% of the total, while slightlyrestricted cultivated land made up 29.7% of the total area. The potential theoretical improvement in cultivated landquality ranges from 0 to 1, which could increase the cultivated land area by one grade to 22237.10 hectares. The ac.tual improvement potential also falls within the 0 to 1 range, which could increase the cultivated land area by onegrade to 17873.36 hectares. Simultaneously, the key points of improving cultivated land quality in the phase are pro.posed, with the research findings serving as a valuable reference for enhancement and promotion efforts in this area. |
