With the rapid economic and social development, it is asked for higher request of flood control and drought relief, the most strict water resources management of hydrology, water conservation and other aspects. However， as the base of hydrological business，Hydrologic Survey still has many incompatible that can not follow the development of economic society and hydrological cause. According to reasonable division patrol measuring area, a reasonable combination of human and material resources, to strengthen the management of hydrological base, vigorously promote hydrologic is earnestly practice "hydrology" development concept, the full implementation of the Ministry of water resources on the deepening of the reform and development of water conservancy decision to deploy, the inevitable requirement to improve the monitoring capacity of the water, there are easier for the hydrologic work based on water conservancy, serve the society. In this paper, according to the basic situation of Hydrology in Ji'an, further demonstrates the necessity and feasibility of hydrological survey, the hydrological survey area is divided into preliminary exploration of the inspection organization and management model.
