南通城市土地抗震适宜性评价及区划方法研究

Study on Seismic Suitability Evaluation and Zoning Method of Urban Land in Nantong

随着南通市城市建设进入快车道,提高城市的防灾减灾能力将直接影响到城市的可持续发展,对南通市城市土地进行抗震适宜性评价和区划意义重大。文章利用GIS的空间数据插值功能,将南通城市土地适宜性评价指标进行量化。利用matlab数据分析得到各评价指标权重,通过建立Logistic回归模型,计算得到该区域地震灾害概率,实现量化评价城市土地抗震适宜性的目的。

As the construction of Nantong city enters the fast lane,improving the disaster prevention and reduction ability of the city will directly affect the sustainable development of the city.In this paper,the spatial data interpolation function of GIS is used to quantify the evaluation index of urban land suitability in Nantong.The weights of each evaluation index were obtained through matlab data analysis.The probability of earthquake disaster in this region was calculated through the establishment of Logistic regression model,so as to achieve the purpose of quantitative evaluation of the seismic suitability of urban land.
