| Some Opinions on the Groundwater Exploitation for Agricultural Production in Northern China |
| Large-area land and abundant photo-thermal resources constitute favorable factors for agricultural production in northern China. However, due to complicated natural conditions, the shortage of water resources restricts the agricultural development. Groundwater has many advantages over surface water: because of its large storage, it remains available in dry seasons or drought conditions;it is cheaper to develop; as it is unpolluted, its treatment is relatively easy;it can be pumped on a stage-by-stage basis where needed;and it is less affected by catastrophic events. It can thus be seen that groundwater is an important water resource for agricultural production in northern China. In this paper, the potential of groundwater resource in the main plains and basins is evaluated. Based on the viewpoint of sustainable utilization of groundwater resource, this paper deals with the problems in groundwater exploitation for agricultural production. Considering the specific conditions in the groundwater over-exploitation areas, the paper also puts forward the countermeasures in such groundwater areas as over-exploitation areas, grave over-exploitation areas, approximate balance areas and considerable potential areas. |
