Abstract
A groundwater function evaluation systems and associated model was applied to Pingtan Island in China, to support future development, use and protection of groundwater. Groundwater function was assigned to resource, ecology and geological environmental functions, and then further sub-divided, based on hydrogeological conditions, development status, planning and Chine policy requirements. At the same time, it is the first time to try to apply the technical requirements for the division of groundwater resources in island areas. According to the planning and utilization of groundwater resources in Pingtan Island, established a second-level system of shallow groundwater function zoning. Then, by comparing the strong and weak relationships among the groundwater resource function, ecology function, and geological environment function, developed a scoring system of the shallow groundwater function zoning. The division of shallow groundwater function zones in Pingtan Island was finally carried out. The zoning result will play an essential role in the future development, utilization, and protection of groundwater in Pingtan Island. At the same time, it provides the first example for the application of groundwater function zoning in island areas and improves the theoretical results of groundwater function zoning.
Highlights
Groundwater resource refers to the amount of underground water that can meet the needs of human production and life in a period and can be replenished and restored every year [1]
In 2006, the Ministry of Land and Resources compiled “Groundwater function evaluation and technical zoning requirements” According to the technical requirements, the functional zoning is mainly applicable to the Quaternary groundwater system in Northwest China, North China, and Northeast China
According to the unit data and weight of each element index corresponding to the three attribute indexes, the resource function evaluation was completed through the spatial analysis function of ArcGIS
Summary
Groundwater resource refers to the amount of underground water that can meet the needs of human production and life in a period and can be replenished and restored every year [1]. It is an important part of water resources. Groundwater resources play an essential role in human production and living, ecological environment and geological environment. Utilization of groundwater resources, there are some problems such as groundwater level decline, seawater intrusion and land subsidence [2]. The excessive exploitation and utilization of groundwater seriously affects the groundwater function and threatens the long-term development of society and the economy
