SUMMARY

Sustainability of the geological environment of Hà Nội City and its change
during the urbanization process

Trần Văn Hoàng, Bùi Thị Bảo Anh

 

Geological environment consists of the highest part of the lithosphere with basic properties, such as deformity, heterogeneity, symmetry, auto-adjustment, sustainability, etc...

Based on componential factors the Hà nội City has been divided into three I, II, and III subareas corresponding to geological environments having the high, middle and low sustainability. Basing on concrete data on the lowering level of groundwater table in the last years and the rate of land subsidence caused by the withdrawal of groundwater in the subareas I, II, III, the authors set up different stages of change in the sustainability of these subareas.
