| description | <p>Land subsidence, as a surface response to the
development, utilization and evolution of underground space, has become a
global and multidisciplinary complex geological environment problem. Since
the 1960s, land subsidence has been developing rapidly in
the Beijing Plain area. Against the backdrop of the integration of Beijing,
Tianjin and Hebei in addition to “southern water” (South-to-North Water Diversion
Project, SNWDP) entering Beijing, the systematic study of the evolution
mechanism of land subsidence is of great significance for the sustainable development of the
regional economy. Firstly, this study used ENVISAT ASAR and RADARSAT-2 data
to obtain surface deformation information for the Beijing Plain area from
2004 to 2015 and then verified the results. Secondly, the study area was divided
into units using a <span class="inline-formula">960 m×960 m</span> grid, and the ground settlement rate of each
grid unit from 2004 to 2015 was obtained. Finally, the Mann–Kendall test was
performed on the grid to obtain the mutation information for each grid unit.
Combined with hydrogeology and basic geological conditions, we have attempted to
analyze the causes of the mutations in the grid. The results show that 2347
grid cells were mutated in a single year, with most of these distributed
across the Yongding River alluvial fan and the middle and lower parts of
the Chaobai River alluvial fan. A total of 1128 grid cells were
mutated in multiple years, with the majority of these cells mainly distributed across the
upper-middle area of the alluvial fan, near the emergency water source and
at the edge of the groundwater funnel. This study aims to provide favorable
technical support and a scientific basis for urban construction in Beijing.</p> |
