Abstract

Sedimentary characterization of modern floods helps to reconstruct the hydrologic flood process and spot the source area of sediment erosion. It is of great referential value both to the design of flood-control works and the identification of paleo-flood layers. In mid-August 2018, two typhoons battered the Dan River Basin in northern Shandong, leading to flooding disasters. Based on the research of the flooded area, the boreholeDH1 of 21 cm long was obtained from the downstream with well-preserved flood sediments. The analyses on its grain size, loss on ignition, magnetic susceptibility, and sporo-pollen features, show that the sedimentary cycle under flooding is characterized by fine grains in the lower part and coarse grains in the upper part. Modern soil is developed at a depth of 11.5~21.0 cm; a typical flood silt layer is developed at a depth of 0~9.0 cm, which is relatively coarse in grain size, dominated by medium-to-coarse-grained silt, and with a sand content of 14.7% on average; and a fine-grained sedimentary layer is developed at a depth of 9.0~11.5 cm during the initial period of flooding. According to the various traits of sensitive component contents, the flooding process can be divided into two stages: the relatively weak hydrodynamic force at the earlier stage and the significantly accelerated flow velocity at the later stage; The former is characterized by severe vicious flow and deposition of clays under the combined action of natural conditions and human activities, which can be further divided into two sub-sections of the rising water level and the significant acceleration of flow velocity; The latter result in typical silty deposits from flooding. Carbonate, organic matter content, and sporo-pollen abundance all are negatively correlated with grain size, indicating that the weak hydrodynamic environment is conducive to its deposition and accumulation. The sporo-pollen assemblage of the surface soil can better indicate the distribution of vegetation in the study area, and the sporo-pollen assemblage of the silty layer from flooding can better reflect the overall condition of vegetation in the basin, which has revealed that the river flood is much greater than wind in transporting sporo-pollen. In addition, the sporo-pollen assemblage features in the clayey layer from flooding are in good agreement with the distribution of vegetation in the study area, and obviously different from those of the silty layer from flooding, according to which it is speculated that the primary cause of the water level rise during the initial period of flooding lies in precipitation incorporating with local surface runoff; therefore, the sediment and sporo-pollen are derived from within the study area, and meanwhile the influx of tourists in the later period has brought in more sporo-pollen from mountainous vegetation. The sporo-pollen deposition records from borehole DH1 show that the sporo-pollen assemblage features are in good response to the propagation process and hydrodynamic force, and have the potential to identify the source area of sediment erosion. The magnetic susceptibility mainly reflects the intensity of pedogenesis, and its value for both the clayey and silty layers from flooding is steadily low, significantly lower than that for the soil contact layer. Therefore, it can be used as a reliable indicator for identifying flood deposits, but the geospatial scope of their use needs to be further discussed.

46. The Occurrence of Microplastics Pollution in the Surface Water and Sediment of Lake Chenghai in Southwestern China.

Abstract

Microplastics (MPs) in freshwater environments, such as lakes, have become a significant issue in recent years. However, studies on the lakes of the Yunnan Plateau have been limited. To understand the pollution status and sources of MPs in Lake Chenghai (LCH), 36 sampling sites were selected for the surface water and sediment samples. Morphological identification, compositional analysis, abundance measurement, and spatial distribution mapping of the MPs were carried out. We also performed correlation analyses with hydrological parameters and physicochemical indexes of water and sediments. We aimed to uncover the spatial distribution patterns of the MPs in LCH, along with potential sources. Our findings revealed that all samples contained MPs and all of them were fibers. The abundance of MPs ranged from 90 to 770 n/m3 (329.44 rms) in the water and from 10 to 115 n/kg (43.19 rms) in the sediments, with particle sizes of 1-3 mm and less than 1 mm, respectively. Transparent MPs were prevalent, comprising 68% of the MPs found in the water and 63% in the sediments. The primary components of the MPs were polypropylene (PP), polyethylene terephthalate (PET), and man-made fibers (rayon). The spatial distribution showed an increasing concentration of MPs from south to north in the surface water, whereas the opposite trend was found in the sediments. Human activities, prevailing winds, and the river flowing into the lake influenced the spatial distribution pattern of the MPs. The abundance and assemblage characteristics of the MPs were directly correlated with the factors of nitrogen, phosphorus, and particle size in the water and sediments, but the correlation was not significant. The main source of MPs was the production and livelihoods of the neighboring residents, especially the use of fishing gears and nets. Since LCH shows significant pollution from MPs, there is an urgent need to control and manage the watershed in order to reduce the input of MPs in the future. [ABSTRACT FROM AUTHOR]

Abstract

The history of agricultural development is of great importance to understanding the evolution of human societies. In this respect, one important location is the Hei River Basin (HRB), an ecotone in northwestern China where prehistoric patterns of cultivation are known to have changed significantly. To identify the factors behind the subsequent development of agriculture in the HRB in the historical period, a hitherto under-researched topic, we employed paleoclimate records, historical documents, radiocarbon dating, and archaeobotanical analyses from seven ancient cities and one large settlement. The results demonstrated a shift from mixed-crop farming to the cultivation of (mainly) barley and wheat during the Wei, Jin Northern and Southern dynasties, Song-Yuan and early Ming period, with the latter crop increasingly predominant. Technological innovations and increased labour power brought about by external population migration resulting from geopolitical changes in northern China were likely responsible for the shift in crop cultivation in the HRB, rather than climate change. This study provides important archaeobotanical evidence for the agricultural development of the HRB over the historical period and highlights multiple factors that seem to have influenced the evolution of agriculture in the region.
