The properties of soil and water loss and organic carbon loss from red soil small watershed under different land use patterns were studied in Zhejing province. The results showed that runoff
sediment and loss of organic carbon concentrated in May
June and August when runoff accounted for 68.78%~73.08% of total loss in a year and both sediment and organic carbon accounted for more than 90% of total loss in a year. The amount of runoff and sediment in bed load form mainly were highest in catchment 5 with less covering vegetation and without soil conserving practice
next extensive farming catchment 1 with less comprehensive measurements for soil conservation
intensive farming catchment 2 and catchment 4 with comprehensive measurements for soil conservation
catchment 3 with vegetation conservation. The amount of loss of organic carbon was highest in catchment 1
next catchment 2
catchment 4
catchment 5 and catchment 3. The amount of organic carbon loss in runoff was equal to that in bed load. From the view of natural resource protection
vegetation conservation practice was the best way to control soil and organic carbon loss. From the point of agricultural production
soil conservation farming practices was the best way both for soil conservation and agricultural production.
