Groundwater Function Zoning for Groundwater Management Based on RSF, EEF, and GEF in the Plain of the Central Plains Urban Agglomeration, China

Groundwater function zoning is an important means to ensure that groundwater plays its various functions, which can provide a scientific basis for the protection and development of resources. Water resources are scarce in Central Plains Urban Agglomeration (CPUA), so it great significance evaluate vulnerability zone this area. In study, resource supply (RSF), eco-environment (EEF), geo-environment (GEF) were analyzed using analytic hierarchy process (AHP), maximum method, dominant mark as divide shallow plain CPUA. The results show reservation areas (32.0%) distributed from Luoning County Yanjin County, Changyuan Xinzheng near mountainous south geological-disaster-prone (29.5%) Ruyang Luohe City, Weihui Jiyuan Xingyang Changge Yuanyang Kaifeng City. utilization (6.4%) ecologically vulnerable (7.5%) east City northeast Xinxiang conservation (24.6%) Wuyang north Xuchang order better manage groundwater, study evaluates DRASTIC model makes single indicator sensitivity analysis. accuracies indicators D, A, I particularly evaluation. According land use types, some suggestions put forward. research reference management CPUA other areas.
