Survey Details |
|
2.1
Dates of erosion monitoring survey: |
1990-1994 |
|
2.1
Water/wind erosion? |
Water |
|
2.3
Area monitored: |
16
km2 |
|
2.4
Character of area: |
Red
soil and purple soil; cultivated land; barren land; subtropical
monsoon climate |
|
2.5
Frequency of monitoring: |
Varied
depending on the times of rain |
|
2.6
What fraction of fields in the monitored area were included
in the survey? |
Only
fields that eroded |
|
2.7
How were estimates of erosion made? |
Measurement
of volume of runoff, soil loss |
|
2.8
Were air photographs used? |
Available
for some years but not relied upon |
|
2.9
For each erosion site, information recorded: |
Location
(Xingguo County, Jiangxi Province). Contributing area (km2-from
map). Slope length (m-from map). Gradient (deg-from clinometer).
Slope shape (convex etc.-from map). Erosion form (interrill,
rill and gully erosion). Volume soil moved (ton). Crop type
(some rice). Management factors (mostly barren land). Soil type
(red soil, etc.). |
|
|
2.10
Data obtained from elsewhere: |
Rainfall
responsible for erosion. Soil samples taken and analysed |
|
2.11
Data calculated from above information: |
Erosion
rate (ton/ha). Timing of erosion (date) |
|
2.12
Meterological station density and type: |
One
manual daily raingauges in area. One automatic gauge |
|
2.13
Length of record of meterological data: |
Start
of daily recording ranges from 1984 to 1994 |
