北京地面沉降与地下水开采时空演变对比
Contrastive analysis of spatial-temporal evolution between land subsidence and groundwater exploitation in Beijing
摘要
Abstract
Regional land subsidence is one of the city diseases which many cities in the world must be facing.Excessive exploitation of groundwater is the most common reason for urban land subsidence.Land subsidence is particularly significant due to groundwater exploitation in Beijing.Based on a method combining qualitative and quantitative analysis,a contrastive analysis of spatial-temporal evolution between land subsidence and groundwater exploitation during 60 years was carried out in the paper in order to understand the new characteristics of land subsidence distribution with new conditions of groundwater exploitation and promote implementation of Beijing Land Subsidence Control Program (2013-2020).The results showed that it was quite consistent in the temporal patterns of formation and development between land subsidence and groundwater exploitation;the spatial-temporal distribution of land subsidence center area was highly correlated with the changes of groundwater depression cone;the primary subsidence layers gradually shifted to deeper formation (with depth more than 100 m) along with the increase of the mining depth of groundwater.These findings will provide the basis for decision-making of land subsidence control.关键词
