Abstract

The natural groundwater recharge in Asia is estimated to be 4 677.74×109 m3/a. However, it features extremely uneven spatial-temporal distribution. Groundwater is distributed in various natural and geological environments, and it is liable to be affected by numerous factors and possesses different properties. Moreover, groundwater faces complex ecological problems. This paper gains a complete understanding of groundwater in Asia in terms of the structure of aquifer systems, the processes of groundwater cycle, and the spatial variation laws of surface ecosystems. Based on this, it proposes the ecological function zoning scheme of groundwater in Asia, aiming to provide guidance for the utilization of regional water resources and the planning for economic and social development, coordinate the relationship between social and economic development and water resource protection, and improve the ecological functions of groundwater. Furthermore, this paper analyzes the problems with regional groundwater management in Asia and puts forward countermeasures and suggestions, thus providing a theoretical basis for the sustainable development and utilization of regional groundwater and environmental protection.
