摘要
耕地分等定级实质上是对耕地质量的评价,客观的评价是以构建科学的评价模型为基础的。通过对近年来耕地分等定级评价模型与方法的较系统分析和比较,试图在分析各种模型特点和精度的基础上,提出各模型的适应范围与条件,从而为模型的进一步拓展和应用提供一定的理论依据,同时也期望能更好的指导耕地分等定级实践。
The cultivated land classification and gradation is virtually an evaluation of the quality of the land, in which the impersonal appraisal is the foundation. By analyzing and comparing the appraisal models and methods used in recent years, this paper attempts to recommend the range and conditions of the models according to the characteristics and precision of the models, thus providing some theoretical basis for thr further development and application of the models.
