The amount is typically calculated as the surface infiltration supply (including natural supply and production supply). Therefore, the exploitation of groundwater resources should generally not exceed the make-up volume, otherwise it will cause environmental damage and deteriorate ecological conditions. The evaluation problem of the resources should be said, and the resources correspond to the development degree of the human society, so that the evaluation of the groundwater resources with the dynamic renewable characteristic should be carried out at different periods of social development, and scientific basis is provided for the national development planning in time.
