土壤质量评价方法述评

Review on methods of soil quality evaluation

为全面总结土壤质量评价方法的研究进展,从指数法、模型法及GIS的参与等方面综述当前一些定量评价土壤质量的方法。指数法计算方法较简单、实用;模型法具有较强的逻辑性和系统性;应用GIS评价土壤质量客观且潜力大,对土壤进行时空动态监测以实现土壤持续经营管理。在土壤质量评价工作中将定量与定性评价结合起来,选择适宜的土壤质量评价指标,不断完善现有的评价方法,发挥信息技术的优势,为合理开发利用土壤提供依据。

In order to sum up the development of soil quality evaluation methods completely, some quantitative evaluation methods within recent years were summarized, including index method, model method, and method of Geographic Information System （GIS） and so on. Index method was relatively simple and practicable, and model method had obvious lagicality and system. The evaluation method based on GIS was objective, and had greater potential capacity, and soil could be managed continuously with the dynamic monitoring method. In the future, to provide the basis for reasonable development and use of soil, the quantitative estimation and qualitative estimation should be combined in appraise of soil quality, the feasible indexes of soil quality should be selected, the existing appraised methods should be consummated constantly, and the predominance of information technique should be brought into play.
