| 摘 要： | 研究目的:探寻农用地自然质量分等和耕地地力评级结果间的差异与联系.实现其成果的衔接研究方法:模糊综合指数评判法、聚类分析法、层次分析法、GIS叠加分析法、转移矩阵分析、拟合分析。研究结果:(1)农用地自然质量分等和耕地地力评价结果之间等、级变化差异程度不同,同一评价单元农用地自然质量等较多高于耕地地力评价级;(2)平原区等与级结果的差异程度远大于丘陵区;(3)建立了不同指标区农用地自然质量指数与耕地地力评价指数之间的衔接模型,丘陵区衔接模型的线性相关程度明显高于平原区。研究结论:利用衔接模型,可以在农用地自然质量分等和耕地地力评级结果间进行转换,实现了两者在同一指标区的相互衔接检验和不同指标区之间的统一可比性。
