Water budget and its variation in Hutuo River basin predicted with the VIP ecohydrological model FARONG HUANG1,2 & XINGGUO MO1 1 Key Laboratory of Water Cycle & Related Land Surface Processes, Institute of Geographical Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing, 100101, China. 2 University of Chinese Academy of Sciences, Beijing, 100049, China [email protected] Abstract Accurate assessment of water budgets is important to water resources management and sustainable development in catchments. Here the VIP (Vegetation Interface Processes) ecohydrological model is used to estimate the water budget and its influence factors in Hutuo River basin, China. The model runs from 1956 to 2010 with a spatial resolution of 1 km, utilizing remotely sensed LAI data of MODIS. During the study period the canopy transpiration takes up 58% of evapotranspiration over the whole catchment and the fractions of soil and interception evaporation are 36% and 6% respectively. The annual evapotranspiration and streamflow are both declining, mainly resulting from the decrease of annual precipitation. Attribution analysis shows that the contributions of climate change and human activities to the decrease of streamflow are 48% and 52%, respectively. Key words streamflow; evapotranspiration; Hai River Basin; VIP model; climate change; human activities 1 INTRODUCTION In the past decades, the surface water of Hai River basin in north China has decreased steadily. It is important to assess the water budget, its long-term variation and impact factors for this area.

Moreover, the monthly and seasonal scale also need to be investigated. In this paper, we investigated the characteristics of changes in annual, seasonal, and monthly hydroclimatic variables, including R, P, T, sunshine duration (SD), relative humidity (RH), and wind speed (WS), between 1956 and 2015 in the Hutuo River basin (HTRB) using the nonparametric Mann-Kendall test, the cumulative anomaly test and the Precipitation-Runoff double cumulative curve method. Additionally, we assessed the contributions of climatic factors to changes in R in the HTRB between 1956 and 2015 using the climate elasticity method. The results indicated that significant downward trends were found for both annual and seasonal R, SD, RH, and WS.

In this paper, hydro-climatic data from four catchments (i.e. Luanhe River catchment, Chaohe River catchment, Hutuo River catchment and Zhanghe River catchment) in the Haihe River basin from 1957 to 2000 were used to quantitatively attribute the hydrological response (i.e. runoff) to climate change and human activities separately. To separate the attributes, the temporal trends of annual precipitation, potential evapotranspiration (PET) and runoff during 1957–2000 were first explored by the Mann–Kendall test. Despite that only Hutuo River catchment was dominated by a significant negative trend in annual precipitation, all four catchments presented significant negative trend in annual runoff varying from À0.859 (Chaohe River) to À1.996 mm aÀ1 (Zhanghe River). Change points in 1977 and 1979 are detected by precipitation–runoff double cumulative curves method and Pettitt’s test for Zhanghe River and the other three rivers, respectively, and are adopted to divide data set into two study periods as the pre-change period and post-change period.

  • On the Road to a Modern City: New Transportation Technology and Urban Transformation of Tianjin, 1860-1937 a Dissertation Submi
    ON THE ROAD TO A MODERN CITY: NEW TRANSPORTATION TECHNOLOGY AND URBAN TRANSFORMATION OF TIANJIN, 1860-1937 A DISSERTATION SUBMITTED TO THE FACULTY OF UNIVERSITY OF MINNESOTA BY Kan Li IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Liping Wang, Ann Waltner June 2020 © Kan Li 2020 Abstract After the northern Chinese city of Tianjin was opened as a treaty port in 1860, the steamship, railroad, and electric tramway were introduced into the city in rapid succession. The adoption of modern transportation technologies enabled Tianjin to occupy a crucial position in the emerging national and global transport and trade networks, Tianjin thus became one of a few cities that made the transition from a traditional commercial city on the Grand Canal to a modern seaport and railroad hub. Instead of taking a city’s modernity for granted, this dissertation examines how the physical forms of modernity came into being in Tianjin by connecting these processes to the adoption of new technologies and the building of national and international networks of transportation. Studying Tianjin from this angle, this dissertation sheds light on why, during the late nineteenth and early twentieth centuries, a select few cities thrived even as China as a whole was struggling economically and politically. While fundamentally transforming Tianjin’s status, these new transport technologies also led to unintended consequences, which revealed the contingencies in modernization and the complexity of the Chinese modernity. In order to make the port of Tianjin a high-capacity, reliable harbor for large steamships, the river connecting Tianjin with the sea was drastically reshaped during the first two decades of the twentieth century.

Overall examination of the context of desertification and defects of desertification-combating programmes is a prerequisite for desertification control, which is now attracting general concern in China. The physiographic circumstances of north China, including the dry, continental, mid-latitude climate, easily erodible soil surface and water shortage, provide the background to desertification. Climatic aridity and the evolution of land use and land management in recent decades have produced great stress on the land. The ineffectiveness of anti-desertification measures ascribed to inadequate scientific involvement in decision-making, neglect of the human dimension and the lack of a well-organized desertification monitoring system are discussed in this paper. Copyright # 2005 John Wiley & Sons, Ltd. key words: desertification; combating desertification; land degradation; water deficiency; sustainability; north China INTRODUCTION Desertification, defined in the Convention to Combat Desertification and Drought in 1994 as ‘Land degradation in arid, semiarid and dry sub-humid areas resulting from various factors including climatic variability and human activities’, began long ago.

To ensure the sustainable management of water resources, it is important to evaluate how dam construction may affect surface runoff. In this study, using Mann–Kendall tests, the double mass curve method, and the Budyko-based elasticity method, the effects of climate change and human activities on annual and seasonal runoff were quantified for the Yellow River basin from 1961–2018; additionally, effects on runoff were assessed after the construction of the Xiaolangdi Dam (XLD, started operation in 2001) on the Yellow River. Both annual and seasonal runoff decreased over time (p < 0.01), due to the Citation: Zhao, Q.; Ding, S.; Ji, X.; combined effects of climate change and human activities.
