Magnitude of Annual Soil Loss from a Hilly Cultivated Slope in Northern Vietnam and Evaluation of Factors Controlling Water Erosion
Annual Soil Loss a Hilly Cultivated Slope Northern Vietnam Water Erosion
2009/12/2
A soil erosion experiment was conducted in northern Vietnam over three rainy seasons to clarify the magnitude of soil loss and factors controlling water erosion. The plot had a low (8%) or medium (14....
The Relationship between Slope Position and Stand Structure of an Old Chamaecyparis obtusa Plantation in Northern Kyoto Prefecture,Japan
L-function old-aged forest plantation slope thinning
2009/8/24
We analyzed the size and spatial distribution of trees in relation to slope position in a 90-year-old Chamaecyparis obtusa plantation, which has never been thinned. The study plot was on a steep slope...
