| 摘 要： | 农田土壤肥力受自然因素和人为因素的双重影响 ,对其进行客观的综合评价显得非常困难 ,为了在对农田土壤肥力综合评价过程中尽量避免主观性 ,减少人为因素 ,人们更多地采用一些数学方法参与到评价过程中 ,进行数值化综合评价。本文就目前流行的有关土壤肥力综合评价的方法进行了介绍和比较 ,并对其取样技术、评价指标最小数据集的选择以及数值化综合评价方法进行了详细介绍。随着GPS、GIS技术的发展 ,土壤肥力质量评价系统会日臻完善 ,为土壤资源的合理利用提供依据。

| Abstract: | It seems very difficult to assess the farmland fertility quality generally and objectively, because of influences from both natural and human factors. In order to avoid the subjectivity in the evaluation processes, some mathematical methods were introduced to this field in recent years, with which the numerical evaluation can be conducted. This paper introduced and compared several evaluation methods of farmland fertility. At the same time, it has introduced the sampling techniques, minimum database systems of evaluation indicators, and numerical methods of integrated evaluation in detail. With the development of GPS and GIS, the evaluation methods of soil fertility quality will be more perfect, which provide theoretical basis for the rational use of soil resources. |
