Abstract: The spatio-temporal variation of precipitation under global warming had been a research hotspot. Snowfall is an important part of precipitation, and its variabilities and trends in different regions have received great attention. In this paper, the Haihe River Basin is used as a case, and we employ the K-means clustering method to divide the basin into four sub-regions. The double temperature threshold method in the form of the exponential equation is used in this study to identify precipitation phase states, based on daily temperature, snowfall, and precipitation data from 43 meteorological stations in and around the Haihe River Basin from 1960 to 1979. Then, daily snowfall data from 1960 to 2016 are established, and the spatial and temporal variation of snowfall in the Haihe River Basin are analyzed according to the snowfall levels as determined by the national meteorological department. The results evalueted in four different zones show that (1) the snowfall at each meteorological station can be effectively estimated at an annual scale through the exponential equation, for which the correlation coefficient of each division is above 0.95, and the relative error is Citation: Wu, X.; Li, S.; Liu, B.; Xu, D. -
Society Interactions: Water Control Projects in Qing China, 1750–1850
‘Public Interest’ as a Basis for Early Modern State– Society Interactions: Water Control Projects in Qing China, 1750–1850 WENKAI HE Division of Social Science Hong Kong University of Science and Technology Clear Water Bay, Kowloon, Hong Kong Email: [email protected] ABSTRACT The safeguarding of public interest was an important means to legitimate state power in the period between 1720 and 1850 in Qing China. Social his- torians have highlighted the vital importance of autonomous management and financing to water control on the part of local gentry in localities in China. However, there were limits to the capacity of social actors for self-financing and self-management in cross-regional water control projects, especially when considering the rivalry of interests between upstream and downstream areas, between people living along the opposite banks of major rivers, and between commercial transportation and irrigation needs. This paper examines the po- litical process by which the Qing state behaved as an ‘impartial’ guardian of the public interest in both financing and settling cross-regional conflicts of interest over water. By examining cases of petitions involved in such hydraulic projects, this paper also shows how collusion between local gentry and govern- ment officials often sacrificed the public interest and how this problem could not be corrected by the political participation of a wider range of social actors. KEY WORDS Qing China, public interest, water control, public finance, petition INTRODUCTION Large-scale water management projects are important infrastructural facili- ties which contribute significantly to public goods in a society. But they often cause serious conflicts of interest. -

Assessment of River Habitat Quality in the Hai River Basin, Northern China
Int. J. Environ. Res.

Academic Editor: Paul B. Tchounwou Received: 9 July 2015 / Accepted: 24 August 2015 / Published: 17 September 2015 Abstract: We applied a river habitat quality (RHQ) assessment method to the Hai River Basin (HRB); an important economic centre in China; to obtain baseline information for water quality improvement; river rehabilitation; and watershed management. The results of the assessment showed that the river habitat in the HRB is seriously degraded. Specifically; 42.41% of the sites; accounting for a river length of 3.31 × 104 km; were designated poor and bad. Habitat in the plain areas is seriously deteriorated; and nearly 50% of the sites; accounting for a river length of 1.65 × 104 km; had either poor or bad habitats. River habitat degradation was attributable to the limited width of the riparian zone (≤5 m); lower coverage of riparian vegetation (≤40%); artificial land use patterns (public and industrial land); frequent occurrence of farming on the river banks and high volumes of solid waste (nearly 10 m3); single flow channels; and rare aquatic plants (≤1 category). -

Ecological variables Macroinvertebrate over multi-spatial scales and macroinvertebrate community data were collected in June (normal flow season) Community structure and September (high flow season) of 2017 in the Weihe River Basin (WRB). A total of 14,377 individuals were Ecological factors identified, which were classified into 7 classes, 18 orders and 59 families. Macroinvertebrate community The Weihe River Basin composition, density, biomass, the values of Pielou evenness index (E), Simpson diversity index (λ) were sig- nificantly different between normal flow season and high flow season. The dominant species (Tubificidae, Chironomidae and Baetidae) were the same in both seasons. The highest richness, abundance, density and biomass occurred at a stream bed depth of 0–10 cm. The results of canonical correspondence analyses (CCA) showed that ecological factors explained the major variation in macroinvertebrate community composition. -

These anomalies are likely influencing vegetation dynamics and ecosystem stability. This paper aims to have a comprehensive understanding of vegetation growth response towards the precipitation pattern in the Huang-Huai-Hai River Basin. The study used NDVI (Normalized Difference Vegetation Index) data and mapped precipitation datasets from 1982 to 2011. NDVI and precipitation show a similar spatial distribution: they decrease from the southeast coast to the northwest inland. -
