To elucidate soil and water conservation benefits of Phyllostachys nigra

simulated rainfalls were carried out in both Phyllostachys nigra forest and slope farmland

and the average sediment concentration and contents of nitrogen and phosphorus were determined. The resulted show that in Phyllostachys nigra forest

the runoff coefficient was 0. 096

with average sediment concentration of 0.26 ~

average content of nitrogen of 0. 152 rag/L

and average content of phosphorus of 0. 453 mg/L. In contrast

slope farmland had a runoff coefficient of 0. 299

with average sediment concentration of 0.99%

nitrogen content of 0. 198 6 mg/L

and phosphorus content of 0. 530 4 mg/L. The findings implies that Phyllostachys nigra forest ex-hibited clearly better benefits in regard to water and soil conservation than slope farmland.
