Investigation of soil erosion on terraced fields near Yanting, Sichuan Province, China, using caesium-137


, : Investigation of soil erosion on terraced fields near Yanting, Sichuan Province, China, using caesium-137. Erosion, debris flow and environment in mountain regions: proceedings of the International Symposium held at Chengdu, China, 5-9 July 1992: 155-168

Much of the agricultural land in the Central Hills area of the Sichuan Basin is at risk from soil erosion by water. An investigation of rates and patterns of soil erosion on agricultural land near Yanting was undertaken using the caesium-137 technique. Erosion of the upper parts of sloping fields was found to be severe, with annual rates of the order of 20 to 50 t/ha.

Antibodies to glutamate (Glu) were used to study the effects of reduced afferent input on excitatory neurons in the somatic sensory cortex of adult monkeys. In each monkey, immunocytochemical staining was compared to thionin and cytochrome oxidase...
