摘要:
[目的] 综合土地利用条件对耕地质量的影响,科学评判"增减挂钩"项目占补耕地数量质量综合平衡情况,为科学推进"增减挂钩"占补平衡工作提供技术支撑。[方法] 以四川省都江堰市为研究区,借鉴已有耕地质量评价相关成果,模拟"增减挂钩"项目,利用新构建的占补耕地数量质量综合平衡关系模型和可实现性预判模型,综合评估了项目耕地占补平衡情况。[结果] 研究区占补耕地数量质量综合平衡判别值(K)为-11.82%,表明模拟项目未实现占补耕地数量质量综合平衡;而占补耕地数量质量综合平衡可实现性预判值(Q)为1.42,说明模拟项目补充耕地数量质量具有达到占用耕地数量质量综合水平的潜力。[结论] 新构建的模型能够实现对"增减挂钩"项目占补耕地数量质量综合平衡情况和可提升潜力的快速分析和判别。

Abstract:
[Objective] The effects of land use conditions on farmland quality, and the balance of quantity and quality of farmland occupied and replenished in increasing urban construction land and reducing rural residential areas project were scientifically evaluated, in order to provide technical support for the scientific promotion of the work.[Methods] Taking Dujianyan City of Sichuan Province as a study area, referring to the existing achievements of cultivated land quality evaluation, the project was simulated. And the balance relationship model and achievability prediction model for the quantity and quality of farmland were contructed and used to evaluate the balance of farmland occupation and compensation.[Results] The balance discriminant value of the quantity and quality of the occupied and replenished farmland in the study area was -11.82%, which indicated that the simulation project had not achieved the balance of the quantity and quality of the farmland. The balance achievability prediction value of the quantity and quality of the occupied and replenished farmland was 1.42, which indicated that the quantity and quality of farmland supplemented by the simulation project had the potential to reach the comprehensive level of the quantity and quality of the occupied farmland.[Conclusion] The models constructed in this paper can realize the rapid analysis and discrimination of the comprehensive balance of the quantity and quality of the farmland and the improvement potential in project of increasing urban construction land and reducing rural residential areas.
