Preliminary study on sediment resources utilization in irrigation districts along the lower Yellow River;

Furthermore,from such aspects as sediment source,coast landform and morphology, longshore sediment transport in the sea area is qualitatively analyzed.

Based on the research findings of predecessors,the sediment source and movement trends of offshore sediment are analyzed and the valuations to sediment conditions of habour construction are given,from field geomorphic survey and grain size analysis of bed material on surface layer in offshore zone of planned coal harbor project.

Gully erosion and mass movement products, sloping cultivated land and grass land were the major sediment sources in all the gullies of the Xiaojiang River basin.

The authors analyze the surface sediment diameter characteristics in the east of Haikou Bay using EOF method,and draw some conclusion on the sediment sources and main hydrodynamics factors which control the sediment transport in the east of Haikou Bay.

Several methods for estimating sediment yield and identifying sediment sources are introduced, compared and evaluated.

In this paper, the fundamental principium and applications of using 238 U and 232 Th decay series radionuclides to research sediment sources,erosion and deposition were reviewed.

This paper analyzed the feature of water and sand resources of the Yellow River between Huayuankou and Jiahetan and the state of field water supply and requirement in irrigation regions along the Yellow River.

As important research on sustainable development of fragile ecosystem, resources management of desertification land attracts people s attention gradually.

Analysis in resources industrilization of desertification land of Heilongjiang Province;
