不同模型在土壤质量评价中的应用研究进展

Advances in Application of Models in Soil Quality Evaluation

土壤质量是土壤特性的综合反映,自20世纪70年代土壤质量的概念提出以来,人们通过各种评价模型进行了不同地区、不同类型的土壤质量评价,但目前仍缺乏通用、简便的评价模型。综述了灰关联综合评价模型、属性层次模型、模糊综合评价模型、物元模型、基于RAGA的PPC/PPE模型和辅以GIS的土壤质量综合评价模型在土壤质量评价中的应用及展望。

Soil quality is a comprehensive reflection of soil properties,Since the soil quality concept was put forward in 1970s,soil quality of different type soils in different regions have been evaluated through a variety of evaluation methods,but still lack of universal used soil quantity evaluation models and methods.In this paper,the applications and prospects of grey relevancy comprehensive model,attribute hierarchical model,fuzzy comprehensive model,matter-element model,RAGA-based PP model and GIS model in soil quality evaluation are reviewed.
