Interactive Effects of Moss-Dominated Crusts and Artemisia ordosica on Wind Erosion and Soil Moisture in Mu Us Sandland, China

Table 4

Annual wind erosion of moss-dominated crusts alone plots (MDCs), bare sand plots (BS), Artemisia ordosica alone plots (AO), and Artemisia ordosica combined with moss-dominated crusts plots (AO + MDCs) in 2011.

Treatment plot	Annual wind erosion (t·ha^−1·a^−1)	Efficiency of reducing wind erosion (%)	Contribution of MDCs to reducing annual wind erosion (%)
MDCs	51.5±7.0^bc	90.6±3.2^a	90.6±3.2^a
BS	592.5±132.5^a	0.0^c
AO + MDCs	18.5±10.0^b	96.3±2.5^a	21.3±7.5^b
AO	135±26.0^c	75.0±10.0^b

Note: different letters in the same column indicate significant differences at 5% probability level.
Efficiency of reducing wind erosion = (1 − annual wind erosion in current treatment/annual wind erosion in BS) × 100.
Contribution of MDCs to reducing wind erosion = ((1 − annual wind erosion in current treatment with MDCs/BS) − (1 − annual wind erosion in current treatment without MDCs/BS)) × 100.
