Experimental Study on Soil and Water Conservation Effects of Different Grasslands with Simulated Rainfall in Yili River Valley
[Objective] The reduction effects of runoff and sediment in 3 different grasslands runoff plots were observed under certain rainfall condition in Yili river valley
to provide references for soil and water conservation in the area.[Methods] Method of field artificial rainfall was used.[Results] (1) The occurrences of initial runoff the several grasslands ranked as:Pod quinoa > Yili Artemisia > Bermuda grass > bare land; (2) The runoff of rate ranked as:bare land > Yili Artemisia > Bermuda grass > Pod quinoa; (3) The sediment concentration ranked as:bare land > Yili Artemisia > Bermuda grass > Pod quinoa; (4) The values of flow reduction factor of Pod quinoa
Bermuda grass and Yili Artemisia were 0.02~0.11
0.21~0.58 and 0.14~0.87. The values of sediment reduction factor of Bermuda grass
Pod quinoa and Yili Artemisia were 0.16~0.76
0~0.42 and 0.42~0.88.[Conclusion] Pod quinoa got the best benefit for soil and water conservation
