- Abstract:
- Artemisia ordosica is one of the dominant plant species in Ordos Plateau. However, The minimum sampling area (MSA) for A.ordosica community had been never studied, And the sampling areas in previous studies on A.ordosica community were ununiform. The representation of samling was higher with the increase of sampling area, But it also increased the workload of community investigation. Here MSA for A.ordosica community in Ordos Plateau were studied by fitting 10 community species-area relationship equations. The results showed that the MSA for A.ordosica community including 60%, 70%, 75%, 80%, 85% and 90% of community species were about 4.77~6.34 m2, 10.45~12.62 m2, 15.48~18.52 m2, 20.20~26.50 m2, 25.95~37.12 m2 and 34.06~50.99 m2, Respectively; And there was no significant change of vegetation cover when sampling area is greater than 4 m×4 m. Therefore, Considering the result of species-area curve and the change of vegetation cover, We figured out that the MSA for A.ordosica community in Ordos Plateau is 16 m2(4 m×4 m).
