The results indicate that with the increase of pumping flow, the absolute values of pumping and recharging drawdown increase linearly, but the pumping temperature decreases. To the aquifer prone to heat transfixion, smaller temperature difference of pumping and recharging and larger pumping flow should be adopted under the permission conditions.
