| 摘 要： | 地面沉降易损性为承灾体易于受到地面沉降的破坏与损害的程度.根据易损性指标的科学性、可操作性以及可定量化等基本选取依据和地面沉降的损失特征,选择单位面积GDP、建筑密度、人口密度、耕地密度和沉降速率五个易损性指标,另外选取一个修正性指标抗损失能力对易损评价结果进行修正.利用贡献率方法确定了各指标的权重.地面沉降易损性定量...

| Abstract: | The vulnerability of land subsidence refers to the sensitivity of hazard bearing body to the damage of land subsidence.On the basis of the scientific features,the maneuverability,and the quantification of vulnerability indexes and on the loss features from land subsidence,the five vulnerability indexes such as the GDP per unit area,building density,population density,plowland density and subsidence rate are selected,and the vulnerability assessment is modified by choosing the index of anti-loss capability.T... |
