Abstract Climate change and intensified human activities are regarded as the two driving factors for most river systems having lost their connection with the Tarim River. The Hotan River is the second largest headstream of the Tarim River; therefore, it is important to determine the causes of its reduction in streamflow supply. Based on an analysis of changes in hydro-meteorological regime and the effects of direct human activities on streamflow, their contributions to the decrease in streamflow in different periods (natural period, 1964–1988; transition period, 1989–2002; post-transition period, 2003–2012) from the Hotan River to the Tarim River were quantified based on a double-mass curve of inflow and outflow in the Hotan River Basin. The results indicate that climatic changes reduced streamflow during the transition period yet increased streamflow during the post-transition period. Human activities reduced output by 73% in the transition period and by 127% in the post-transition period, which was significantly stronger than the contribution from the climate. Thus, human activities appear to be the main driving factor for the drop in streamflow from the Hotan River into the Tarim River. These results can be used as a reference for water resource planning and management.

Impacts Of Climate Change

The impacts of climate change on annual runoff were analyzed using hydrologic and meteorological data collected by 8 meteorological stations and 15 hydrological stations in the headstream of the Tarim River Watershed from 1957 to 2005. The long-term trend of climate change and hydrological variations were determined by parametric and non-parametric tests. The results show that the increasing scale of precipitation is less than the scale of rising temperature. The change and response of hydrological process have their own spatial characteristics in the tributaries of a headstream. Precipitation and temperature do not increase simultaneously in the hydro- and meteo-stations located in the headstream. The temperature and runoff displayed certain relations, and a relationship also existed between precipitation and runoff. The annual runoff of the Aksu and Kaidu rivers was consistent with an increasing trend in temperature and precipitation during the past 50 years; temperature increases have a greater effect on annual runoff. These results suggest that with the increase of temperature in the Tarim River Watershed, the glacier in the headstreams would melt gradually which results in runoff increase in several headstreams. However, glacier meltwater would be exhausted due to continual glacier shrinkage, and the increased trend of runoff in the headstreams would also slow or lessen. Thus, regional water resources shortage problems are still serious and have become a major feature in the Tarim River Watershed.
