An inspection system, combined by three non-parametric tests and fuzzy recognition, is introduced to investigate the hydrological variation trends. Based on the meteorological & hydrological data and land use at 9 reservoir-controlled basins in Northeast China, the trend analyses were performed concerning the variation of inflow and its driving factors (i. e. precipitation, annual precipitation distribution, evaporation and land use). According to the results, the reservoir basins studied are classified into three types. One type of basins, mainly influenced by climate, includes Tang River, Biliu River, Guanyinge and Shenwo reservoir basins. The second type takes land use as its significant driving factor, including Naodehai and Fengman reservoir basins. The third type has good natural conditions, consists of Baishan, Huanren and Dahuofang reservoir basins. Furthermore, on the basis of the above conclusions, the recommendations for research direction and reservoir management in future are put forward, which will promote further analyses of hydrological change in reservoir-controlled basins, Northeast China.
