| 摘 要： | 土壤质量评价与监测是评价土壤退化的重要工作,也是重新设计持续性的土壤管理系统的基础。目前缺乏统一的评价指标以及将各项土壤性质与土壤管理措施结合起来的评价方法。本文首先提出了选择红壤质量评价指标的原则,并从化学、物理学和生物学三个方面初步探讨了评价红壤质量动态变化可资采用的指标体系,综述了国内在南方丘陵区红壤质量演化的研究中应用的指标;最后从土地评价方法中选择了可用于红壤质量评价的方法,并简要综述了国际上最新的土壤质量评价方法。

| Abstract: | Being important for evaluation of soil degradation, monitoring and assessment of soil quality is a sound basis for updating the designs of sustained soil management system. But now there is a lack of uniform indexes for evaluating soil quality changes, and the methods to integrate the main soil properties with soil management practice are also meager for the same purpose. In this paper, principles of selecting indexes for red soil quality evaluation are put forward firstly. And then an index system applicable to evaluating dynamic changes in red soil quality is approached from chemical, physical and biological aspects. Indexes used to conduct research on evaluation of red soil quality in hilly region of South China are reviewed. Besides, the methods from land assessment are chosen for evaluation of red soil quality, and some new methods for soil quality assessment in the world are outlined, too. |
