“…This result is consistent with previous findings based on observations in highlatitude regions (Walvoord and Striegl, 2007;St. Jacques and Sauchyn, 2009;Ye et al, 2009) and in northeastern China (Liu et al, 2003). However, those studies did not consider spatial variability.…”

“…Several studies reported that permafrost thawing might enhance base flow in the arctic and the subarctic (Walvoord and Striegl, 2007;St. Jacques and Sauchyn, 2009;Ye et al, 2009), as well as in northeastern China (Liu et al, 2003;Duan et al, 2017). A few studies reported that permafrost thawing might reduce river runoff (here, runoff is defined as all liquid water flowing out of the study area), especially on the Qinghai-Tibetan Plateau (QTP) (e.g., Qiu, 2012;Jin et al, 2009).…”

“…Consequently, regional patterns and long-term trends are not typically captured. Longterm meteorological and hydrological observations are available in many areas, but they do not provide information on soil freezing and thawing processes (McClelland et al, 2004;Liu et al, 2003;Niu et al, 2011). Therefore, previous observation-based studies have not provided a sufficient understanding of the long-term changes in frozen soils and their impact on regional hydrology (Woo et al, 2008).…”

Abstract. Frozen ground has an important role in regional hydrological cycles and ecosystems, particularly on the Qinghai-Tibetan Plateau (QTP), which is characterized by high elevations and a dry climate. This study modified a distributed, physically based hydrological model and applied it to simulate long-term changes in frozen ground its the effects on hydrology in the upper Heihe basin, northeastern QTP. The model was validated against data obtained from multiple ground-based observations. Based on model simulations, we analyzed spatiotemporal changes in frozen soils and their effects on hydrology. Our results show that the area with permafrost shrank by 8.8 % (approximately 500 km 2 ), predominantly in areas with elevations between 3500 and 3900 m. The maximum depth of seasonally frozen ground decreased at a rate of approximately 0.032 m decade −1 , and the active layer thickness over the permafrost increased by approximately 0.043 m decade −1 . Runoff increased significantly during the cold season (November-March) due to an increase in liquid soil moisture caused by rising soil temperatures. Areas in which permafrost changed into seasonally frozen ground at high elevations showed especially large increases in runoff. Annual runoff increased due to increased precipitation, the base flow increased due to changes in frozen soils, and the actual evapotranspiration increased significantly due to increased precipitation and soil warming. The groundwater storage showed an increasing trend, indicating that a reduction in permafrost extent enhanced the groundwater recharge.

“…However, frozen soil experienced a significant degradation trend coupled with a significant climate warming [47,48]. Due to warmer temperature, the increase in active layer thickness of permafrost has two effects on hydrological processes as well as the response of streamflow to climate change: (1) more water for evaporation and hence fewer water yield for streamflow; and (2) more water storage in the soil layers and less surface streamflow generation.…”

Assessment of the response of streamflow to future climate change in headwater areas is of a particular importance for sustainable water resources management in a large river basin. In this study, we investigated multiscale variation in hydroclimatic variables including streamflow, temperature, precipitation, and evapotranspiration in the Headwater Areas of the Nenjiang River Basin (HANR) in China's far northeast, which are sensitive to climate change. We analyzed 50-year-long records of the hydroclimatic variables using the ensemble empirical mode decomposition (EEMD) method to identify their inherent changing patterns and trends at the inter-annual and inter-decadal scales. We found that all these hydroclimatic variables showed a clear nonlinear process. At the inter-annual and inter-decadal scales, streamflow had a similar periodic changing pattern and transition years to that of precipitation; however, within a period, streamflow showed a close association with temperature and evapotranspiration. The findings indicate that the response of streamflow in headwater regions to climate change is a nonlinear dynamic process dictated by precipitation at the decadal scale and modified by temperature and evapotranspiration within a decade.

“…Significant climate change would greatly affect the agro-ecosystem and its management in the region. Therefore, historical climate reconstruction of the area would be critical for the understanding of the ecosystem sustainability of the future (Liu et al 2003;Jiang et al 2009). Fossil pollen and sediment cores from local lakes demonstrated a long-term warming trend which started many thousands of years ago (Tareq et al 2006;Makohonienko et al 2008;Stebich et al 2009).…”

At the treeline, tree growth rate is known to be very sensitive to climate change. Width of tree rings is often used to estimate climatic conditions when direct measures of temperature and precipitation at the site are unavailable. In this study, tree ring data and available site-specific climatic data were analysed and correlated to reconstruct historical temperature changes from 1849 to 2008 at the Changbai Mountain treeline. One hundred and seventy-five Betula ermanii trees were selected from seven plots at the upper treeline area on the north-facing slopes of the Changbai Mountains. Two hundred and ninety-one tree ring cores were extracted from these trees to develop the B. ermanii chronology. The tree ring width index was found to be significantly related (R 2 = 0.43, p < 0.01) to the mean annual temperature at the Tianchi weather station nearby during the period of 1953-2008. A transfer function was developed from the relationship to reconstruct the mean annual temperature from 1849 to 1952, for which a climatic record at Tianchi were unavailable. The results suggest a wavelike temperature increase with alternations between rapid warming and gentle cooling periods at the Changbai Mountains treeline for the 160 years. In Northeast China, the temperature has increased 0.07°C per decade with significant fluctuation (p < 0.05, SD = 0.64) according to the extrapolated data. The extrapolation is based on the relationship between the Tianchi station and the other 164 weather stations throughout the Northeast. Temperature increase would significantly affect the sustainability of the alpine ecosystems in the Changbai Mountains as well as the agro-ecosystem management of the Northeast China Plain, a designated farmland area for crop production by the Chinese government.
