摘要

识别洪水易发地区的风险对于支持风险管理决策是必要的。本研究旨在建立Pontianak市洪水灾害易损性模型。该模型基于生物物理因素的评分和加权。采用层次分析法和逻辑公式建立模型。结果表明,采用层次分析法确定Pontianak市洪水易损性的模型准确率为80%。使用逻辑公式确定洪水易损性等级的模型准确率为84%。模型1的Kappa精度值为76.7%。洪水易损性模型说明,Pontianak市大部分地区的洪水易损性水平非常高,为31,440,568.8 m2,占总研究面积108,003,319.8 m2的29.11%。脆弱区面积为29945485.7 m2,占总面积的27.73%;欠安全区面积为22126936.3 m2,占总面积的20.49%;安全区面积为24490328.7 m2,占总面积的22.67%。本研究有助于政府在未来制定有关洪水管理和城市发展的政策,并努力减轻洪水。Doi: 10.28991/CEJ-2023-09-04-02全文:PDF

Spatial Modeling of Flood-Vulnerability as Basic Data for Flood Mitigation
Identifying risks in flood-prone areas is necessary to support risk management decisions. This research was conducted to establish a vulnerability model of flood hazards in the city of Pontianak. The model was based on the scoring and weighting of biophysical factors. The AHP method and logical formulations were used to establish the model. The result showed that the accuracy of the model used by AHP to determine the vulnerability of floods was 80% in Pontianak City. The accuracy of the model using logical formulations to determine the vulnerability level of a flood was 84%. The Kappa accuracy value in model 1 is 76.7%. The model of flood vulnerability explains that most of Pontianak City has a very high level of flood vulnerability, which is 31,440,568.8 m2 or 29.11% of the total research area of 108,003,319.8 m2. The vulnerable area is 29,945,485.7 m2 or 27.73%, and the less safe area is 22,126,936.3 m2 or 20.49%, with the safe area being 24,490,328.7 m2or 22.67% of the total area. This research contributes to the government to establish policies regarding flood management and urban development in the future, and as an effort to mitigate against flooding. Doi: 10.28991/CEJ-2023-09-04-02 Full Text: PDF
