“…It spans four countries including China, Kazakhstan, Kyrgyzstan, and Uzbekistan in the east-west direction. It stretches around 2500 km length with an average width of 250-350 km (Hu, 2004, Chen et al, 2014Wang et al, 2011). The 15 East Tianshan Mountains is called the Chinese Tianshan Mountains (CTM) which extends over 1700 km in Xinjiang Province, China (Figure 1).…”

Abstract. The Chinese Tianshan Mountains has a complex ecological environment system. It not only has a large number of desert oases, but also gave birth to a large number of glaciers. The arid climate and the shortage of water resources are the important factors to restrict the socio-economic development in this area. This study presents a unique high-resolution (1 km, 6-hourly) air temperature data set for the Chinese Tianshan Mountains (41.1814-45.9945 °N, 77.3484-96.9989 °E) from 20 1979 to 2016 based on a robust statistical downscaling framework. The data set was validated by 24 meteorological stations at daily scale. Compared with original ERA-Interim temperature, the Nash-Sutcliffe efficiency coefficient increased from 0.90 to 0.94 over all test sites. Around 24% of root-mean-square error was reduced from 3.75 to 2.85 °C. A skill score based on the probability density function, which was used to validate the reliability of the new data set for capturing the distributions, enhanced from 0.86 to 0.91 for all test sites. We conclude that the new high-resolution data set is reliable for 25 climate change investigation over the Chinese Tianshan Mountains. This data set would be helpful for the potential users for better local climate monitoring, modelling and environmental studies in the Chinese Tianshan Mountains. The data set presented in this article is published in Network Common Data Form (NetCDF) at doi: 10.1594/PANGAEA.887700. The data set includes 288 nc files and one user guidance in txt file.

“…The mean annual precipitation was 600-1,400 mm per year and most of the precipitation falls in the form of rain during the four-month period from June through September, i.e., the flood season of the river basin. 32 Monthly variations in the water discharge of the Huai River main channel show an appreciable seasonal variability, with low discharges in dry season (October-May) and high values in wet season (JuneSeptember). The average discharge in July in Bengbu accounts for about 30 % of annual discharge.…”

The causal research design method is most effective in establishing the cause-andeffect associations especially when carrying out findings concerning specific variations on water resources availability and development in relation to several other River Basin operating factors such as human activities, climatic conditions and Land-use. The paper takes advantage of specific scenarios to reveal the trends of relationships between factors measured. It is feasible to analyze the effect and cause for wide range of processes in relation to trends. There are higher levels of internal validity associated with research design method because of systematic subject selection. Present study examines the effects of climate change factors on the processes and relative needs for water uses in domestic, production and eco-water consumption is central to the allocation and conservation of water resources in systems of ecology and economy in arid Northeast of China. The population growth requires adequate supply of water especially during shortages arising melt-water from ice and glacier, abnormal rainfall, and flood disasters. The Soil and Water Assessment Tool (SWAT) has deployed prominently for modelling the physical distribution of hydrology of Huai River Basin to ascertain the influence of land use and climate changes independently. However, its inadequate data causes equivocal and inconsistency results derived from statistical analysis; seemingly poor control measures in the basin; method's cause-effect nature; and restriction to small and headwater basins. The watershed method revealed the effects of climatic conditions and human activities on water resources. However, it is limited by the constant variation to land use patterns usually smaller in large catchments than in small watersheds. There are two small neighbouring watersheds could have same climatic input but not in the case of larger catchments. To solve those problems researchers and stakeholders must find a long-term solution by identifying the affected areas. This paper presents the overview of water resources problem of the basin for future study, plan, and work. Keywords: The effects of human activities, climatic conditions and land-use factors on water resources development in huai river basin northeast china 108Copyright: ©2018 Othman Ali et al.The processes of hydrology are majorly caused by climate and land use. There is ever increasing rate of human advancements giving rise to intense changes universally both in climatic conditions and forms of land-use in catchments. In general, the effects of these changes on environment and ecological advancement are receiving extensive attention.12-15 On a catchment scale, the effects of these processes of hydrology including infiltration, groundwater recharge and runoff continue to adversely take tolls in the sense of balance of water resources' demand and supply and quality of water; thereby causing imbalances in environment, ecosystems, and economy at large. The direct consequences of land use change are ra...

“…The Tianshan Mountain area within China has 7,934 glaciers, and is one of the main distribution areas of alpine mountain glaciers in the world (Liu et al, 2015). Many scientists have analyzed the relationship between climate change and glacier retreat, based on topographic and remote sensing data (Aizen et al, 2007;Kutuzov and Shahgedanova, 2009;Wang et al, 2011). It has been established that the retreat of alpine mountain glaciers was serious over the last 40 years (Bolch, 2007;Kong and Pang, 2012).…”

Inland lakes and alpine glaciers are important constituents of water resources in arid and semiarid regions. Understanding their variations is critical for both an accurate evaluation of the dynamic changes of water resources and the retrieval of climatic information. On the basis of earlier researches, this study investigated the growth of the Sayram Lake and the retreat of its water-supplying glaciers in the Tianshan Mountains using long-term sequenced remote sensing images. Our results show that over the past 40 years, the surface area and the water level of the lake has increased by 12.0±0.3 km 2 and 2.8 m, respectively, and the area of its water-supplying glaciers has decreased continuously since the early 1970s with a total reduction of about -2.13±0.03 km 2 . Our study has indicative significance to the research of regional climate change.
