土壤物理质量指标研究进展及在矿区环境中的应用展望

对土壤物理质量指标在国内外的研究进展进行了系统总结,在矿区环境中的应用进行了展望,构建了矿区环境土壤物理质量指标体系。常规指标的研究集中于耕作或人为干扰对指标影响的定量研究及物理、化学和生物学指标的相互影响。国外提出并应用了许多非常规指标来对土壤物理质量进行评价,结合常规指标,可以对自然或人为扰动情况下,土壤损伤及退化问题进行深入研究。采煤沉陷对土壤物理质量的影响是一个系统和复杂的过程,我国矿区土壤环境的研究,应该基于不同的研究目的,选择正确的常规和非常规指标来对矿区土壤物理质量进行系统的评价、表征及定量化。构建的矿区环境土壤物理质量指标体系,具有一定的参考和应用价值。

A REVIEW OF THE PROGRESS IN THE RESEARCH ON SOIL PHYSICAL QUALITY INDICATOR AND ITS APPLICATION IN THE MINING AREA ENVIRONMENT

In this paper, we summarized research progress of indicator of soil physical quality systematically and its application prospect in mine area environment, and built indicator system of soil physical quality for mine area environment. The main conclusions and suggestions are as following: Much attentions were paid on quantitative research of usual indicators by tillage and human disturbance, and mutual influences among physical, chemical and biological indicators. Scientists overseas introduced and adopted many unusual indicators to evaluate soil physical quality. The unusual indicators, combined with the usual indicators, can be used to conduct deeper research on soil damage and degradation by tillage and human disturbance. Influences on soil physical quality by mining subsidence is a systemic and complicated process, thus, research on soil for mine area environment in China should be based on different purposes to choose the right usual and unusual indicators to systematically evaluate, characterize and quantify soil physical quality in mine area environment. The indicator system of soil physical quality for mine area environment in this paper has certain reference and application values.
