Abstract:
... River valleys are considered natural corridors for migration of plant species; however, there is a lack of studies confirming higher colonisation rates of plant species in these areas. We compare plant species richness between ancient and recent forests (developed during and after the nineteenth century) and those located in a river valley with those located outside the river valley. We hypothesis ...

Abstract:
... In 2020 summer, the excessive rainfall over the Yangtze and Huaihe River valley (YHRV) broke the record held since 1961, and the induced flood disasters caused huge losses. The record-breaking rainfall was primarily attributed to the abnormally strong western Pacific subtropical high (WPSH), characterized by a westward expansion to southern China. The extreme northern India Ocean (NIO) warming and ...

... The rural revitalization strategy is a key strategic deployment to resolve the “San Nong” (Agriculture, Rural Areas, and Farmers) issue and attain agricultural and rural modernization in the new era. The strategy has practical significance in determining the differentiation principle of rural areas, identifying their development types, and elucidating the goal orientation of rural revitalization. ...

Abstract:
... Previous works extensively investigated the influences of the winter–spring Tibetan Plateau snow cover (TP, TPSC) on climate variability over the East Asia. The present work documents an interdecadal-changed impact of distinct spring TPSC anomaly (TPSCA) patterns on spring precipitation over eastern China (SPEC) around the early 1990s. It is found that the connection between the eastern and wester ...

... In the present study, inner Kumaun Himalayan region between village Jauljibi and Dobaat along the Kali river has been studied to understand the causes and the distribution of landslides in the area. Various geomorphic indices such as longitudinal and topographic swath profile, stream length gradient index, steepness index, and valley floor width to valley height ratio have been extracted for inter ...

... This paper provides an important archive of the largest paleoflood event along the Gold Gorge of the upper Hanjiang River, with a review of regional extraordinary flood magnitudes using historical, gauged, and paleoflood datasets. Paleoflood slackwater deposit (SWD) was identified using the sedimentological criteria and high-resolution physicochemical indexes. End-member model demonstrates the pal ...

Abstract:
... Urbanization provides benefit to modern civilization, while it also creates a series of ecological issues at different scales. The study of landscape pattern and connectivity change caused by urban agglomeration is the hotspot of regional ecological security research. In this study, morphological spatial pattern analysis (MSPA) and Patch Importance Index (dPC) were used to evaluate landscape heter ...

Aiming at the extensive management problems in ecological operation and ecological irrigation, this paper proposed a novel ecological irrigation method—ecological infiltration irrigation (EII), and established a multi-scale ecological operation model of reservoir group coupled with EII for the irrigation and restoration of river valley grasslands. Firstly, the ecological available water supplies i ...

As a part of “The Vltava River” project, it was necessary to create a visualisation of the historic Vltava River valley before the construction of the so-called Vltava Cascade (nine dams built in the Vltava River basin between 1930 and 1992). Vectorisations of the Imperial Obligatory Imprints of the Stable Cadastre, and a terrain model created from contour lines from the State Map 1:5000-Derived ( ...

Abstract:
... Numerous damming landslides have occurred at the southeastern margin of the Tibetan Plateau due to intense tectonic activities, strong river erosion, and extreme climate change. A Late Pleistocene paleo-landslide damming event has been detected in the Induba area in the upstream reaches of the Jinsha River, preserving various river-blocking phenomena, such as landslide dammed deposits and fluvial ...

Situated in the Salawusu River Valley in the southeast of China’s Mu Us Desert, the Milanggouwan stratigraphical section MGS1 has recorded 11 sedimentary cycles, consisting of alternations between dune sands and fluvial or lacustrine facies. This paper analyzed the distribution of grain-size and Zr/Rb ratios in the MGS1, which is located in the arid and semi-arid areas of North China, and grain-si ...

Abstract:
... The contribution of early human activity to the increase in atmospheric CH₄ content during the middle to late-Holocene is still debated. The quantitative reconstruction of past changes in land use by early rice agriculture is a key to resolving the issue, because large uncertainties still exist in current prehistoric land use estimates, owing to a lack of direct records. In this study, we used the ...

... Located in the transitional region between northern and southern China, the middle Han River valley is of pivotal significance for current debates on rice domestication and the formation of mixed farming in early China. Based on phytoliths and macro-plant remains from 10 sites, along with radiocarbon dating, this study has narrowed the 2000-year gap in early rice utilization by 700 years in the mi ...

... BACKGROUND AND OBJECTIVES: In China, breeders overlook changes in grain quality traits of starch, protein, and fat content that occur concurrently in normal maize (Zea mays L.). Here, we collected data for 436 single‐cross normal maize varieties released since the 1960s and 258 landraces from China's three main agroecological regions to investigate how grain quality traits have changed over time. ...

... In the rich of archaeological sites dated from the late Palaeolithic to the Modern Period region of the Serteyka River, deposits of an extensive accumulative fan were studied in detail. In the lower sector of the present-day Serteyka River valley, the strict chronology and depositional conditions of an extensive accumulative fan deposits were studied in detail. An important part of the project has ...
... Assessment of genotoxicity of aquatic ecosystems is of great importance for environmental management and assessment of water ecological quality as well as health safety. Data on the genotoxicity of water in rivers of such a large region as Siberia are almost absent. Researchers do not pay enough attention to river floodplains, but such studies are important for assessing the ecological condition o ...

... Paleolithic rock paintings are known from many parts of the world, including Africa, Australia, Europe and Island Southeast Asia. However, no Paleolithic rock paintings have yet been confirmed in the East Asia mainland, partly due to the lack of suitable dating materials. The rock paintings distributed at more than 70 sites in the Jinsha River valley, Yunnan Province, southwestern China, include t ...

To minimise the impact of slope instability on vital transport infrastructure, as well as on terrestrial and aquatic ecosystems, public safety, communities, local heritage, and the economy, and to better inform decision making, ...
... In the northwest Indo-Gangetic plains, the linkage of the Ghaggar-Hakra paleochannel with the Sarasvati River of early Indian literature and the Harappan (or Indus) civilization poses an important case for understanding drainage reorganization and human-landscape interactions. Among the major paleochannels of the Ghaggar-Hakra, sediment provenance studies on the paleo-Sutlej branch show its connec ...
... Little is known about the impact of long-term intensive irrigated rice cropping on secondary macro and micronutrients in soils and crops. Therefore, the present study analysed the effect of intensive irrigated rice cropping on nutrient concentrations in soils and rice (grain and straw at harvest) in two long-term experiments that were established in 1991 for intensive rice-based irrigated systems ...
