- 摘要:
- 为保持现有耕地质量等级成果现势性，本文分析了年度内土地变更引起耕地质量变化的情况和原因，探讨了耕地质量更新评价方法和思路。以土地整理和评价理论方法为指导，运用农用地等别评定方法，修正方法中的土地利用、土地经济等相关系数，对质量变更的耕地进行评价。根据耕地变更不同的原因建立对应的耕地质量等级更新方法。以武汉市汉南区为实证研究，在汉南区2010年耕地质量等级调查与评价成果的基础上，对汉南区2012年的耕地质量等级做了年度更新。实证研究结果显示：汉南区年度内减少耕地233.85 hm2；新增耕地49.08 hm2，主要为二、三等地；质量变化耕地1 669.29 hm2，质量均有所提升。实证研究验证了更新方法的可行性，对全国全面进行耕地质量等级年度更新工作提供了理论和实践依据。
- Abstract:
- For the purpose of maintaining the present situation of existing cultivated quality grading achievement, this paper analyzed the cases and reasons of cultivated land quality changes. It also discussed the methods and ideas of updating cultivated land quality evaluation. This paper used the agricultural land evaluation method to evaluate the quality-changing cultivated land with modifying the coefficient of land utilization and land economic under the guidance of land consolidation and evaluation theory. It built the corresponding cultivated land grade updating methods based on the different reasons of cultivated land changes. Then it completed the annual updates of cultivated land quality evaluations in Hannan of Wuhan City in 2012 based on the cultivated land quality investigation and evaluation results as a solid evidence in Hannan in 2010. This study stated that Hanan existing cultivated land decreased by 233.85 hectares in that year. The 49.08 hectares of newly reclaimed cultivated land were classified as the second or third level. The quality of the 1 669.29 hectares of cultivated land had been improved. This study confirmed the feasibility of the updating method and also provided theoretical and practical basis for national annual update of cultivated land quality grades.
