The relation between preventing or controlling flood and drought resistant is analyzed. In order to thoroughly overcome ravages of a constantly escalating drought, it is a important measure to augment groundwater by reverse dredge theory and reverse dredge engineering, traditional engineering join force with reverse dredge engineering, safely regulate water resource in land spatial field and let land have sufficient water resource in every season. It can not only free from drought of the Haihe basin and others basin, but also broke bottleneck restrict of water resource in agriculture and industry.
