摘要：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.

摘要：本论文针对填海区绿地的抗风灾能力评估问题,基于澳门填海区的特殊地理条件,提出了一套综合性的评估方法。研究引入了层次分析法(AHP)、熵权法和模糊综合评价法相结合的数学方法,并结合GIS技术,对填海区绿地的抗风能力进行定量分析。通过层次分析法确定关键指标的相对权重,熵权法修正权重的客观性,最终利用模糊综合评价法对抗风能力进行综合打分,并通过GIS技术进行精细化空间分析。研究结果将为澳门及其他沿海城市的绿地规划和防灾减灾提供科学依据和技术支持,具有广泛的应用价值。In order to evaluate the wind disaster resistance capacity of green space in the reclamation area, this paper proposes a comprehensive evaluation method based on the special geographical conditions of the reclamation area in Macao. In this study, the mathematical method combining analytic hierarchy process (AHP), entropy weight method and fuzzy comprehensive evaluation method was introduced, and GIS technology was combined to quantitatively analyze the wind resistance capacity of green space in the reclamation area. The relative weight of key indicators is determined by the analytic hierarchy process, the objectivity of the weights is corrected by the entropy weight method, and finally the fuzzy comprehensive evaluation method is used to comprehensively score the wind resistance capacity, and the GIS technology is used to carry out refined spatial analysis. The research results will provide scientific basis and technical support for green space planning and disaster prevention and mitigation in Macao and other coastal cities, and have a wide range of application value.
