填海区土壤质量分析方法探究——以澳门为例
A Study on Soil Quality Analysis Methods in Reclamation Areas—A Case Study of Macao

本研究以澳门填海区为例，探讨填海区土壤质量的分析方法。通过实验，采用1%浓度的酚酞试剂酸碱滴定法测定土壤pH值，并使用灼失量法评估土壤中的有机物含量。研究揭示了澳门填海区土壤的pH值分布及有机物含量特征，为填海区土壤质量评价提供了科学依据。研究结果表明，澳门填海区土壤存在显著的酸碱度差异和有机质缺乏问题，影响土壤的生态功能和建筑稳定性。该研究对未来土壤改良和生态恢复具有指导意义，并为填海区土壤管理提供了技术支持。
In this study, we took the reclamation area of Macao as an example to explore the analysis method of soil quality in the reclamation area. Through experiments, the pH value of soil was determined by acid-based titration of phenolphthalein reagent at a concentration of 1%, and the organic matter content in soil was evaluated by loss on ignition method. This study revealed the pH distribution and organic matter content characteristics of the soil in the reclamation area of Macao and provided a scientific basis for the evaluation of soil quality in the reclamation area. The results showed that there were significant pH differences and organic matter deficiencies in the soil in the reclamation area of Macao, which affected the ecological function and building stability of the soil. This study has a guiding significance for future soil improvement and ecological restoration and provides technical support for soil management in the reclamation area.
