中文摘要：
文章对1985～2006年累计地面沉降量及近几年地面沉降速率进行分析和叠加评价，完成天津市滨海地区地面沉降灾害危险性分区图；以人口密度和单位面积GDP为指标进行易损性分析；从每km^2水准测量km数和地下水压采量占开采量百分比两方面考虑防灾减灾能力；在此基础上，借助GIS空间分析方法，将危险性分区图、易损性分区图和防灾减灾能力分区图进行叠加分析，完成天津市滨海地区地面沉降灾害风险区划图，分为低风险区、较低风险区、中等风险区、较高风险区、高风险区5等。
英文摘要：
Risk assessment and zoning are very important for risk management. Accumulative total subsidence volume and land subsidence velocity were analyzed and superimposed to create the land subsidence disaster evaluation map. Population density and unit area GDP were analyzed in terms of vulnerability mapping. Response and recovery capability of land subsidence disaster was also assessed. Land subsidence disaster risk zonation by means of GIS automatically was overlaid on the three data layers of hazard, vulnerability and response and recovery capability. Then each grid unit with a resolution of 200m × 200m was divided into five categories of the risk： high, slight high, medium, slight low and low. The research can give reference to regional disaster reduction.
