This paper reviews the research progress of hydrological variability caused by intensive human activities in the following three subjects: ①For the responses of hydrological elements to human activities, presently two kinds of approaches, qualitative and quantitative analysis, have been put forward. The complex driving factors of human activities to hydrological change were revealed, and a series of hydrological models for quantitative analysis of hydrological response to human activities were developed. ②Some achievements were found in recognition of changing point for time series of hydrological features by mainly using statistic methods, while some new approaches like difference entropy method were used in recognition of hydrological variability, and spatial variation of hydrological elements  studied though this kind of research was just started. ③Two kinds of methods, item by item investigation and hydrological modeling, were set up for decomposing the influences of climate change and human activities on hydrological variation. Mechanism and models describing the impact of land use and land cover change (LUCC) on hydrological variations were developed  and the contribution of LUCC to hydrological changes in the agricultural areas was studied. Through this review, it was found that there exist some shortcomings in the present research in quantitative analysis of hydrological response to human activities, recognition of hydrological variation, and driving mechanism of LUCC to hydrological changes. Therefore, future research in these aspects should be strengthened.
