Holocene and recent valley-bottom sediment storage decouples natural and anthropogenic hillslope erosion from sediment delivery to streams at time scales of 10 1 –10 4 yr in a third-order Yangtze Rive…
To assess the time scales and relative importance of temporal decoupling between hillslope erosion and the introduction of sediment to streams in a Yangtze River headwater basin, we used multiple techniques to date sediments in alluvial fans and terraces in a third-order stream valley draining a 30-km 2 catchment in SW Sichuan, China. Poorly sorted angular sediments in tributary-junction alluvial fans ranged in age from 11261 BCE to 1844 CE, and …
Implications of the loess record for Holocene climate and human settlement in Heye Catchment, Jiuzhaigou, eastern Tibetan Plateau, Sichuan, China
We examine the Holocene loess record in the Heye Catchment on the margins of the Tibetan Plateau (TP) and China Loess Plateau (CLP) to determine: the region to which the Heye Catchment climate is more similar; temporal change in wind strength; and modification of the loess record by mass wasting and human activity. Luminescence and radiocarbon dating demonstrate loess deposited in two periods: >11–8.6 ka and
Agricultural land use doubled sediment loads in western China's rivers
Unintended Side Effects of Conservation
Toward the goals of returning the landscape of Jiuzhaigou National Nature Reserve to a perceived “natural” state and protecting the environment, the Reserve in 1998–2002 implemented forest preservation policies that included restrictions on forestry, agriculture, and animal herding practiced by resident Tibetans. To document the effects of these land use changes on landscape diversity and on human vulnerability to natural hazards, we mapped and c…
Forest is Forest and Meadows are Meadows
Present-day landscapes are shaped by historical forces that combine natural change (generated by climate, geological processes etc.) with anthropogenic change (locally generated in interaction with larger political and economic forces). In the Jiuzhaigou region of Northern Sichuan, humans have shaped landscapes to their needs for at least 3,500 years. In recent centuries, landscape change has probably accelerated, particularly in response to chan…
Early evidence for the use of wheat and barley as staple crops on the margins of the Tibetan Plateau
Significance Adapting agricultural systems to the high-altitude environment of the Tibetan Plateau has long been considered a major challenge for farmers. It has been asserted previously that the ecological characteristics of wheat and barley delayed their spread into East Asia. We argue instead that the ability of these crops to tolerate frost and their low heat requirements facilitated their spread into the high-altitude margins of western Chin…
Traditional Livelihoods, Conservation and Meadow Ecology in Jiuzhaigou National Park, Sichuan, China
The Question of Communist Land Degradation
Chinese Communist Party doctrine promotes the Confucian belief that the environment should be subjugated to man's will, and modern policies have been identified as compounding environmental degradation caused by historical agricultural practices. In this context, social scientists report massive increases in erosion throughout China, an assertion variously supported and questioned by daily sediment yield data in the Yellow and Yangtze River basin…
