【摘要】 把影响农用土地环境质量的所有环境要素综合起来,分解量化指标,重建评价体系,提出宏观指标分等、微观指标定级的新观点,并就县市级农用土地环境质量进行全要素整合评价和等级评定进行了探讨。结果表明,保证评价精度和把握等级评定的关键步骤是正确选择和划分评价单元;土地农业综合生产能力和清洁度指标是农用土地环境质量的综合反映和集中体现,是所有被整合调查要素和评价因素中最重要的两个刚性指标,在评价中必须加大权重;全要素整合评价可以弥补农业或土地部门多指标评价的不足,能够比较全面和客观地反映农用土地环境质量状况。农用土地环境质量的全要素整合评价为新一轮土地利用规划修编、基本农田保护区准确划定、农用土地分等定级和建设用地的区划调整以及土地基准定价能提供有力技术支持。更多还原

【Abstract】 All environmental factors influencing agricultural land environment quality were integrated,quantitative indicators were separated,evaluation system was reconstructed,and the viewpoint of macro index for classifying and micro index for grading was put forward.Agricultural land environment quality in county was graded and classified with all factors evaluation integrated.The results showed that the key steps for improving accuracy and ensuring grade estimation were to select and divide evaluation units;soil overall agricultural productivity and cleanliness embodied agricultural land environment quality,were the most important indexes in all the factors integrated,and the weighing of the two factors should be increased;all factors evaluation integrated could fill the shortcoming of agricultural multi-index evaluation and reveal agricultural land environment quality fully and objectively.All factors evaluation integrated for agricultural land environment quality could provide support for revising the plan of land use,dividing conservation zone of basic farmland correctly,classifying and grading agricultural land,adjusting construction land and putting a basing-point pricing.更多还原
