英文摘要 | The research region is located in the northeast margin of Tarim, which is characterized by a typical continental arid desert climate, with a scanty rainfall and large difference in temperature between day and night. The research region is relatively stable in geology and exposed to the long-term weathering and serious erosion of seasonal surface water, which lead to the typical landform of "planation surface" and Yadan In order to investigate the long-term stability of superficial facilities in this region, a series of methods have been conducted to study the erosion characteristics of soil and rocks in some representative positions, i.e., soil erosion monitoring in different places, modelling analysis of soil erosion, terrestrial cosmogenic nuclides concentration measurement, denudation amount measurement of stone relics, and estimation of regional strata denudation. The results demonstrate that erosion rate is less than 0.3m/10(4)a for sandstone in flat surface, 0.8 m/10(4)a in seasonal gully. The erosion rate of soil is averagely 0.16 similar to 0.19cm/a for palaeo-lacustrine deposition area since late pleistocene epoch, 0.42cm/a for monitoring platform, 3.97cm/a for erosional depression. The denudation rate is estimated to be 0.9 mm/10(4)a for siliceous stone relics, 9.5 similar to 11.6 mm/10(4)a for sandstone and granite relics, and 4.0mm/a for ancient architecture made of soil in research area. By the method of tectonic trend of missing strata, it is estimated that the erosion rate is less than 0.35 m/10(4)a since the tertiary period when a steady stage of uplift and denudation begin in the research region. |
