土壤紧压导致绿化树生长不良的间接诊断原理与实例

The theory and examples of indirect diagnosis on unhealthy growth of greening trees caused by soil compaction

在城市中,土壤紧压是导致绿化树生长不良的重要原因,但现场环境和成本因素限制了利用植物和土壤的理化指标来直接诊断两者的关系。文章总结土壤紧压间接诊断的原理,并结合实例进行分析。

Soil compaction is an important cause of unhealthy growth of greening trees in urban area. It can be diagnosed directly by assessing physical and chemical indices of soil and trees, but special environment and high cost restrict its application. This paper puts forward an indirect diagnosing method. At first, the occurrence of soil compaction is determined by observation on vehicle transportation, then other pathogens are elinimated by reasoning. Finally, two cases were used to illustrate how to apply this method in practice.
