[Objective] The aim of this study is to examine the response of hydrological cycle factors to vegetation dynamics and climate change in the inland river basin of Inner Mongolia grassland, which is of important theoretical significance for the ecological protection and regional water resources development and utilization in the inland river basin of Inner Mongolia grassland. [Methods] The inland river basin of Inner Mongolia grassland was taken as the research area. Based on multi-source remote sensing, climate, meteorology, hydrology and other data, the temporal and spatial evolution and driving factors of hydrological cycle elements in the basin were analyzed by trend test, significance test and correlation analysis. [Results] (1) The evapotranspiration of the basin showed a significant upward trend (0.994 mm/a), the precipitation showed a significant downward trend (1.965 mm/a), and the soil moisture showed an increasing trend. (2) The vegetation in the growing season generally showed an increasing trend. The normalized difference vegetation index (NDVI), gross primary productivity (GPP) and leaf area index (LAI) showed a ladder-like spatial distribution pattern of high level in the east and low level in the west, and the temperature showed an overall upward trend. (3) Vegetation change was positively correlated with evapotranspiration (ET) and soil moisture (SSM). There was a significant positive correlation between temperature and evapotranspiration (R= 0.699, p=0.01), and the spatial correlation increased from west to east. There was a negative correlation between temperature and runoff, and a significant negative correlation with soil moisture in the east and west of the basin. [Conclusion] The hydrological cycle variables (precipitation, evapotranspiration, soil moisture, runoff) increased with the increase of vegetation. Precipitation, soil moisture and runoff decreased with the increase of temperature, and evapotranspiration increased with the increase of temperature. [ABSTRACT FROM AUTHOR]

[Objective] The aim of this study is to explore the change mechanism of runoff and sediment in small watershed, improve and optimize the treatment scheme, and achieve high-quality sustainable ecological development of the Loess Plateau. [Methods] The small watershed of Zhifanggou in Ansai was taken as the research object. Mann-Kendall trend approach and Pettitt mutation test were used to analyze the trend of basin rainfall and sediment discharge, and identify the mutation point, and elastic coefficient method was used to carry out the runoff and sediment change attribution analysis to identify the climate change and human activities on runoff and sediment quantity contribution. [Results]（1） Both runoff and sediment transport showed a decreasing trend, in which the decreasing trend of runoff was not significant, but the decreasing trend of sediment transport was extremely significant.（2） With the change of time, the contribution rate of human activities to runoff change increased gradually.（3） The influence degree of human activities on sediment transport gradually increased with time, and finally tended to 96%. [Conclusion] Human activities are the main influencing factors of runoff and sediment transport, and returning farmland to forest is an effective method for soil erosion control in the Loess Plateau.
